  • What is the difference between a heuristic and a machine learning algorithm? What is the difference between a heuristic and a machine learning algorithm? - What is the difference between a heuristic and a machine learning algorithm? Machine learning algorithms and heuristics are two distinct approaches to problem solving - while both can often yield successful outcomes, they differ in a few key ways. Machine learning algorithms rely heavily on data input, meaning that the more data the algorithm receives, the more it can understand and learn about a specific situation or problem. Heuristics on the other hand use sets of rules and experience to address more complex problems - this approach often results in quicker problem solving due to less ‘thinking’ required on behalf of the algorithm. To sum it up, algorithms are best utilized by AI systems when large amounts of data is available, whereas heuristics prove most effective when context knowledge is at play. It's all a matter of which approach works best for your particular problem!

  • US mid-terms elections 2022 voter participation Can AI predicts US Mid-Terms 2022 Election Winners? - Can AI predicts US Mid-Terms 2022 Election Winners? As the race for the US Mid-Terms in 2022 heats up, many are wondering if AI will be able to predict the winners. While AI has become quite adept at analyzing data and making predictions, US elections are notoriously unpredictable. In 2018, for example, the Democrats unexpectedly lost control of the House, despite predictions that they would maintain a majority. And in 2020, Donald Trump shocked the world by winning reelection, despite most polls showing he would lose. So can AI really predict who will win in 2022? The answer is maybe. AI will be able to take into account a wide range of factors, from poll numbers to fundraising totals to social media buzz. But ultimately, US elections are still largely determined by factors that are impossible to predict, such as which candidate gets the most votes on Election Day. As a result, predicting the US Mid-Term winners in 2022 is still very much a guessing game.

  • How to find common elements in two unsorted arrays with sizes n and m avoiding double for loop? Blog Introduction: In this blog post, we will be discussing how to find common elements in two unsorted arrays with sizes n and m avoiding double for loop. We will be discussing various methods that can be used to solve this problem and comparing the time complexity of each method. Blog Body: Method 1: Linear Search The first method we will discuss is linear search. This method involves iterating through both arrays and comparing each element. If the element is found in both arrays, it is added to the result array. The time complexity of this method is O(nm), where n is the size of the first array and m is the size of the second array. Method 2: HashMap Method The second method we will discuss is the HashMap method. This method involves creating a HashMap of all the elements in the first array. Then, we iterate through the second array and check if the elements are present in the HashMap. If they are, we add them to the result array. The time complexity of this method is O(n+m), where n is the size of the first array and m is the size of the second array. Method 3: Sort andCompare Method The third method we will discuss is the Sort and Compare Method. This method involves sorting both arrays using any sorting algorithm like merge sort or quick sort. Once both arrays are sorted, we compare each element of both arrays one by one until we find a match. If a match is found, we add it to our result array. The time complexity of this method is O(nlogn+mlogm), where n is the size of the first array and m is the size of the second array. Conclusion: In this blog post, we discussed how to find common elements in two unsorted arrays with sizes n and m avoiding double for loop. We discussed three different methods that can be used to solve this problem and compared their time complexities. We hope that this blog post was helpful in understanding how to solve this problem.  How to find common elements in two unsorted arrays with sizes n and m avoiding double for loop? - How to find common elements in two unsorted arrays with sizes n and m avoiding double for loop? One of the most straight forward ways to find common elements in two arrays is by using a double for loop. This approach is simple to understand and implement but it is not very efficient. The time complexity of this algorithm is O(n*m) where n and m are the size of the two arrays respectively. The reason for this is because we are looping through both arrays completely which takes a lot of time. Furthermore, this approach also uses a lot of extra space because we are storing the common elements in a new list.

  • Proxy vs VPN What’s the difference between a proxy and a VPN and why is one security stronger than the other? Which security feature is stronger and why? - What's the difference between a proxy and a VPN and why is one security stronger than the other? Which security feature is stronger and why? In the digital age, proxy servers and VPNs have become increasingly popular as people strive to protect their online privacy and security. But what exactly are these two devices, and how do they differ? A proxy server is a computer that acts as an intermediary between your device and the internet. When you connect to the internet through a proxy, your data is routed through the proxy server before it reaches its destination. This allows you to mask your IP address and remain anonymous online. VPNs, on the other hand, encrypt your data before it leaves your device. This creates a private tunnel that cannot be accessed by anyone except for you and the VPN server. As a result, VPNs offer a higher level of security than proxy servers. However, proxy servers are typically faster and more reliable than VPNs, making them a good choice for online activities that don't require a high level of security, such as web browsing or streaming video.

  • Summary of Machine Learning and Artificial Intelligence Capabilities What is Problem Formulation in Machine Learning and Top 4 examples of Problem Formulation in Machine Learning? - What is Problem Formulation in Machine Learning and Top 4 examples of Problem Formulation in Machine Learning? Problem formulation is an essential part of the machine learning pipeline. Machine learning problems can be classified into four types: regression, classification, clustering, and ranking. Each type of problem has its own set of challenges and requires a different approach. For example, regression problems involve predicting a continuous value, such as the price of a stock, while classification problems involve predicting a discrete label, such as whether an email is spam or not. Clustering problems involve grouping data points into clusters, while ranking problems involve ordering data points from most to least similar. In each case, the goal is to find a model that can generalize from the training data to the test data. The choice of model will depend on the type of problem and the nature of the data. For instance, linear models are often used for regression problems, while decision trees are often used for classification problems. The challenge in machine learning is to find a model that performs well on the training data but also generalizes well to unseen data. This is where problem formulation comes in. By carefully defining the problem and choosing an appropriate model, we can increase the chances of finding a solution that works well in practice.

  • Google PageRank How does using a VPN or Proxy or TOR or private browsing protects your online activity? - How does using a VPN or Proxy or TOR or private browsing protects your online activity? There are several ways that using a virtual private network (VPN), proxy, TOR, or private browsing can protect your online activity: VPN: A VPN encrypts your internet connection and routes your traffic through a secure server, making it harder for others to track your online activity. This can protect you from hackers, government surveillance, and other types of online threats. Proxy: A proxy acts as an intermediary between your device and the internet. When you use a proxy, your internet traffic is routed through the proxy server, which can mask your IP address and make it harder for others to track your online activity. TOR: The TOR network is a decentralized network of servers that routes your internet traffic through multiple servers to obscure your IP address and location. This can make it more difficult for others to track your online activity. Private browsing: Private browsing mode, also known as "incognito mode," is a feature that is available in most modern web browsers. When you use private browsing, your web browser does not store any information about your browsing activity, including cookies, history, or cache. This can make it harder for others to track your online activity. Overall, using a VPN, proxy, TOR, or private browsing can help protect your online activity by making it harder for others to track your internet usage and by providing an additional layer of security. However, it is important to note that these tools are not foolproof and cannot completely guarantee your online privacy. It is always a good idea to be aware of your online activity and take steps to protect your personal information.

AWS Certified Developer – Associate Practice Questions And Answers Dump

Q0: Your application reads commands from an SQS queue and sends them to web services hosted by your
partners. When a partner’s endpoint goes down, your application continually returns their commands to the queue. The repeated attempts to deliver these commands use up resources. Commands that can’t be delivered must not be lost.
How can you accommodate the partners’ broken web services without wasting your resources?

  • A. Create a delay queue and set DelaySeconds to 30 seconds
  • B. Requeue the message with a VisibilityTimeout of 30 seconds.
  • C. Create a dead letter queue and set the Maximum Receives to 3.
  • D. Requeue the message with a DelaySeconds of 30 seconds.


C. After a message is taken from the queue and returned for the maximum number of retries, it is
automatically sent to a dead letter queue, if one has been configured. It stays there until you retrieve it for forensic purposes.

Reference: Amazon SQS Dead-Letter Queues

Q1: A developer is writing an application that will store data in a DynamoDB table. The ratio of reads operations to write operations will be 1000 to 1, with the same data being accessed frequently.
What should the Developer enable on the DynamoDB table to optimize performance and minimize costs?

  • A. Amazon DynamoDB auto scaling
  • B. Amazon DynamoDB cross-region replication
  • C. Amazon DynamoDB Streams
  • D. Amazon DynamoDB Accelerator


D. The AWS Documentation mentions the following:

DAX is a DynamoDB-compatible caching service that enables you to benefit from fast in-memory performance for demanding applications. DAX addresses three core scenarios

  1. As an in-memory cache, DAX reduces the response times of eventually-consistent read workloads by an order of magnitude, from single-digit milliseconds to microseconds.
  2. DAX reduces operational and application complexity by providing a managed service that is API-compatible with Amazon DynamoDB, and thus requires only minimal functional changes to use with an existing application.
  3. For read-heavy or bursty workloads, DAX provides increased throughput and potential operational cost savings by reducing the need to over-provision read capacity units. This is especially beneficial for applications that require repeated reads for individual keys.

Reference: AWS DAX

Q2: You are creating a DynamoDB table with the following attributes:

  • PurchaseOrderNumber (partition key)
  • CustomerID
  • PurchaseDate
  • TotalPurchaseValue

One of your applications must retrieve items from the table to calculate the total value of purchases for a
particular customer over a date range. What secondary index do you need to add to the table?

  • A. Local secondary index with a partition key of CustomerID and sort key of PurchaseDate; project the
    TotalPurchaseValue attribute
  • B. Local secondary index with a partition key of PurchaseDate and sort key of CustomerID; project the
    TotalPurchaseValue attribute
  • C. Global secondary index with a partition key of CustomerID and sort key of PurchaseDate; project the
    TotalPurchaseValue attribute
  • D. Global secondary index with a partition key of PurchaseDate and sort key of CustomerID; project the
    TotalPurchaseValue attribute


C. The query is for a particular CustomerID, so a Global Secondary Index is needed for a different partition
key. To retrieve only the desired date range, the PurchaseDate must be the sort key. Projecting the
TotalPurchaseValue into the index provides all the data needed to satisfy the use case.

Reference: AWS DynamoDB Global Secondary Indexes

Difference between local and global indexes in DynamoDB

  • Global secondary index — an index with a hash and range key that can be different from those on the table. A global secondary index is considered “global” because queries on the index can span all of the data in a table, across all partitions.
  • Local secondary index — an index that has the same hash key as the table, but a different range key. A local secondary index is “local” in the sense that every partition of a local secondary index is scoped to a table partition that has the same hash key.
  • Local Secondary Indexes still rely on the original Hash Key. When you supply a table with hash+range, think about the LSI as hash+range1, hash+range2.. hash+range6. You get 5 more range attributes to query on. Also, there is only one provisioned throughput.
  • Global Secondary Indexes defines a new paradigm – different hash/range keys per index.
    This breaks the original usage of one hash key per table. This is also why when defining GSI you are required to add a provisioned throughput per index and pay for it.
  • Local Secondary Indexes can only be created when you are creating the table, there is no way to add Local Secondary Index to an existing table, also once you create the index you cannot delete it.
  • Global Secondary Indexes can be created when you create the table and added to an existing table, deleting an existing Global Secondary Index is also allowed.

Throughput :

  • Local Secondary Indexes consume throughput from the table. When you query records via the local index, the operation consumes read capacity units from the table. When you perform a write operation (create, update, delete) in a table that has a local index, there will be two write operations, one for the table another for the index. Both operations will consume write capacity units from the table.
  • Global Secondary Indexes have their own provisioned throughput, when you query the index the operation will consume read capacity from the index, when you perform a write operation (create, update, delete) in a table that has a global index, there will be two write operations, one for the table another for the index*.

Q7: You are attempting to SSH into an EC2 instance that is located in a public subnet. However, you are currently receiving a timeout error trying to connect. What could be a possible cause of this connection issue?

  • A. The security group associated with the EC2 instance has an inbound rule that allows SSH traffic, but does not have an outbound rule that allows SSH traffic.
  • B. The security group associated with the EC2 instance has an inbound rule that allows SSH traffic AND has an outbound rule that explicitly denies SSH traffic.
  • C. The security group associated with the EC2 instance has an inbound rule that allows SSH traffic AND the associated NACL has both an inbound and outbound rule that allows SSH traffic.
  • D. The security group associated with the EC2 instance does not have an inbound rule that allows SSH traffic AND the associated NACL does not have an outbound rule that allows SSH traffic.


D. Security groups are stateful, so you do NOT have to have an explicit outbound rule for return requests. However, NACLs are stateless so you MUST have an explicit outbound rule configured for return request.

Q8: You have instances inside private subnets and a properly configured bastion host instance in a public subnet. None of the instances in the private subnets have a public or Elastic IP address. How can you connect an instance in the private subnet to the open internet to download system updates?

  • A. Create and assign EIP to each instance
  • B. Create and attach a second IGW to the VPC.
  • C. Create and utilize a NAT Gateway
  • D. Connect to a VPN


C. You can use a network address translation (NAT) gateway in a public subnet in your VPC to enable instances in the private subnet to initiate outbound traffic to the Internet, but prevent the instances from receiving inbound traffic initiated by someone on the Internet.

Reference: AWS Network Address Translation Gateway


Top

Q9: What feature of VPC networking should you utilize if you want to create “elasticity” in your application’s architecture?

  • A. Security Groups
  • B. Route Tables
  • C. Elastic Load Balancer
  • D. Auto Scaling


D. Auto scaling is designed specifically with elasticity in mind. Auto scaling allows for the increase and decrease of compute power based on demand, thus creating elasticity in the architecture.

Q14: What is one key difference between an Amazon EBS-backed and an instance-store backed instance?

  • A. Autoscaling requires using Amazon EBS-backed instances
  • B. Virtual Private Cloud requires EBS backed instances
  • C. Amazon EBS-backed instances can be stopped and restarted without losing data
  • D. Instance-store backed instances can be stopped and restarted without losing data


C. Instance-store backed images use “ephemeral” storage (temporary). The storage is only available during the life of an instance. Rebooting an instance will allow ephemeral data stay persistent. However, stopping and starting an instance will remove all ephemeral storage.

Q15: After having created a new Linux instance on Amazon EC2, and downloaded the .pem file (called Toto.pem) you try and SSH into your IP address (54.1.132.33) using the following command.
ssh -i my_key.pem ec2-user@52.2.222.22
However you receive the following error.
@@@@@@@@ WARNING: UNPROTECTED PRIVATE KEY FILE! @ @@@@@@@@@@@@@@@@@@@
What is the most probable reason for this and how can you fix it?

  • A. You do not have root access on your terminal and need to use the sudo option for this to work.
  • B. You do not have enough permissions to perform the operation.
  • C. Your key file is encrypted. You need to use the -u option for unencrypted not the -i option.
  • D. Your key file must not be publicly viewable for SSH to work. You need to modify your .pem file to limit permissions.


D. You need to run something like: chmod 400 my_key.pem

Q16: You have an EBS root device on /dev/sda1 on one of your EC2 instances. You are having trouble with this particular instance and you need to either Stop/Start, Reboot or Terminate the instance but you do NOT want to lose any data that you have stored on /dev/sda1. However, you are unsure if changing the instance state in any of the aforementioned ways will cause you to lose data stored on the EBS volume. Which of the below statements best describes the effect each change of instance state would have on the data you have stored on /dev/sda1?

  • A. Whether you stop/start, reboot or terminate the instance it does not matter because data on an EBS volume is not ephemeral and the data will not be lost regardless of what method is used.
  • B. If you stop/start the instance the data will not be lost. However if you either terminate or reboot the instance the data will be lost.
  • C. Whether you stop/start, reboot or terminate the instance it does not matter because data on an EBS volume is ephemeral and it will be lost no matter what method is used.
  • D. The data will be lost if you terminate the instance, however the data will remain on /dev/sda1 if you reboot or stop/start the instance because data on an EBS volume is not ephemeral.


D. The question states that an EBS-backed root device is mounted at /dev/sda1, and EBS volumes maintain information regardless of the instance state. If it was instance store, this would be a different answer.

Q22: What should the Developer enable on the DynamoDB table to optimize performance and minimize costs?

  • A. Amazon DynamoDB auto scaling
  • B. Amazon DynamoDB cross-region replication
  • C. Amazon DynamoDB Streams
  • D. Amazon DynamoDB Accelerator


D. DAX is a DynamoDB-compatible caching service that enables you to benefit from fast in-memory performance for demanding applications. DAX addresses three core scenarios:

  1. As an in-memory cache, DAX reduces the response times of eventually-consistent read workloads by an order of magnitude, from single-digit milliseconds to microseconds.
  2. DAX reduces operational and application complexity by providing a managed service that is API-compatible with Amazon DynamoDB, and thus requires only minimal functional changes to use with an existing application.
  3. For read-heavy or bursty workloads, DAX provides increased throughput and potential operational cost savings by reducing the need to over-provision read capacity units. This is especially beneficial for applications that require repeated reads for individual keys.

Q23: A Developer has been asked to create an AWS Elastic Beanstalk environment for a production web application which needs to handle thousands of requests. Currently the dev environment is running on a t1 micro instance. How can the Developer change the EC2 instance type to m4.large?

  • A. Use CloudFormation to migrate the Amazon EC2 instance type of the environment from t1 micro to m4.large.
  • B. Create a saved configuration file in Amazon S3 with the instance type as m4.large and use the same during environment creation.
  • C. Change the instance type to m4.large in the configuration details page of the Create New Environment page.
  • D. Change the instance type value for the environment to m4.large by using update autoscaling group CLI command.


B. The Elastic Beanstalk console and EB CLI set configuration options when you create an environment. You can also set configuration options in saved configurations and configuration files. If the same option is set in multiple locations, the value used is determined by the order of precedence.
Configuration option settings can be composed in text format and saved prior to environment creation, applied during environment creation using any supported client, and added, modified or removed after environment creation.
During environment creation, configuration options are applied from multiple sources with the following precedence, from highest to lowest:

  • Settings applied directly to the environment – Settings specified during a create environment or update environment operation on the Elastic Beanstalk API by any client, including the AWS Management Console, EB CLI, AWS CLI, and SDKs. The AWS Management Console and EB CLI also applyrecommended values for some options that apply at this level unless overridden.
  • Saved Configurations
    Settings for any options that are not applied directly to the
    environment are loaded from a saved configuration, if specified.
  • Configuration Files (.ebextensions)– Settings for any options that are not applied directly to the
    environment, and also not specified in a saved configuration, are loaded from configuration files in the .ebextensions folder at the root of the application source bundle.        

    Configuration files are executed in alphabetical order. For example,.ebextensions/01run.configis executed before.ebextensions/02do.config.

  • Default Values– If a configuration option has a default value, it only applies when the option is not set at any of the above levels.

If the same configuration option is defined in more than one location, the setting with the highest precedence is applied. When a setting is applied from a saved configuration or settings applied directly to the environment, the setting is stored as part of the environment’s configuration. These settings can be removed with the AWS CLI or with the EB CLI
.
Settings in configuration files are not applied
directly to the environment and cannot be removed without modifying the configuration files and deploying a new application version.
If a setting applied with one of the other methods is removed, the same setting will be loaded from configuration files in the source bundle.

Q28: You’ve written an application that uploads objects onto an S3 bucket. The size of the object varies between 200 – 500 MB. You’ve seen that the application sometimes takes a longer than expected time to upload the object. You want to improve the performance of the application. Which of the following would you consider?

  • A. Create multiple threads and upload the objects in the multiple threads
  • B. Write the items in batches for better performance
  • C. Use the Multipart upload API
  • D. Enable versioning on the Bucket


C. All other options are invalid since the best way to handle large object uploads to the S3 service is to use the Multipart upload API. The Multipart upload API enables you to upload large objects in parts. You can use this API to upload new large objects or make a copy of an existing object. Multipart uploading is a three-step process: You initiate the upload, you upload the object parts, and after you have uploaded all the parts, you complete the multipart upload. Upon receiving the complete multipart upload request, Amazon S3 constructs the object from the uploaded parts, and you can then access the object just as you would any other object in your bucket.

Q29: A security system monitors 600 cameras, saving image metadata every 1 minute to an Amazon DynamoDb table. Each sample involves 1kb of data, and the data writes are evenly distributed over time. How much write throughput is required for the target table?

  • A. 6000
  • B. 10
  • C. 3600
  • D. 600


B. When you mention the write capacity of a table in Dynamo DB, you mention it as the number of 1KB writes per second. So in the above question, since the write is happening every minute, we need to divide the value of 600 by 60, to get the number of KB writes per second. This gives a value of 10.

You can specify the Write capacity in the Capacity tab of the DynamoDB table.

Q31: An organization is using an Amazon ElastiCache cluster in front of their Amazon RDS instance. The organization would like the Developer to implement logic into the code so that the cluster only retrieves data from RDS when there is a cache miss. What strategy can the Developer implement to achieve this?

  • A. Lazy loading
  • B. Write-through
  • C. Error retries
  • D. Exponential backoff

Answer:


Answer – A
Whenever your application requests data, it first makes the request to the ElastiCache cache. If the data exists in the cache and is current, ElastiCache returns the data to your application. If the data does not exist in the cache, or the data in the cache has expired, your application requests data from your data store which returns the data to your application. Your application then writes the data received from the store to the cache so it can be more quickly retrieved next time it is requested. All other options are incorrect.

Q32: A developer is writing an application that will run on Ec2 instances and read messages from SQS queue. The messages will arrive every 15-60 seconds. How should the Developer efficiently query the queue for new messages?

  • A. Use long polling
  • B. Set a custom visibility timeout
  • C. Use short polling
  • D. Implement exponential backoff


Answer – A Long polling will help insure that the applications make less requests for messages in a shorter period of time. This is more cost effective. Since the messages are only going to be available after 15 seconds and we don’t know exacly when they would be available, it is better to use Long Polling.

Q38: A developer is making use of AWS services to develop an application. He has been asked to develop the application in a manner to compensate any network delays. Which of the following two mechanisms should he implement in the application?

  • A. Multiple SQS queues
  • B. Exponential backoff algorithm
  • C. Retries in your application code
  • D. Consider using the Java sdk.


Answer- B. and C.
In addition to simple retries, each AWS SDK implements exponential backoff algorithm for better flow control. The idea behind exponential backoff is to use progressively longer waits between retries for consecutive error responses. You should implement a maximum delay interval, as well as a maximum number of retries. The maximum delay interval and maximum number of retries are not necessarily fixed values, and should be set based on the operation being performed, as well as other local factors, such as network latency.

Q39: An application is being developed that is going to write data to a DynamoDB table. You have to setup the read and write throughput for the table. Data is going to be read at the rate of 300 items every 30 seconds. Each item is of size 6KB. The reads can be eventual consistent reads. What should be the read capacity that needs to be set on the table?

  • A. 10
  • B. 20
  • C. 6
  • D. 30


Answer – A

Since there are 300 items read every 30 seconds , that means there are (300/30) = 10 items read every second.
Since each item is 6KB in size , that means , 2 reads will be required for each item.
So we have total of 2*10 = 20 reads for the number of items per second
Since eventual consistency is required , we can divide the number of reads(20) by 2 , and in the end we get the Read Capacity of 10.

Q41: A static web site has been hosted on a bucket and is now being accessed by users. One of the web pages javascript section has been changed to access data which is hosted in another S3 bucket. Now that same web page is no longer loading in the browser. Which of the following can help alleviate the error?

  • A. Enable versioning for the underlying S3 bucket.
  • B. Enable Replication so that the objects get replicated to the other bucket
  • C. Enable CORS for the bucket
  • D. Change the Bucket policy for the bucket to allow access from the other bucket


Answer – C

Cross-origin resource sharing (CORS) defines a way for client web applications that are loaded in one domain to interact with resources in a different domain. With CORS support, you can build rich client-side web applications with Amazon S3 and selectively allow cross-origin access to your Amazon S3 resources.

Cross-Origin Resource Sharing: Use-case Scenarios The following are example scenarios for using CORS:

  Scenario 1: Suppose that you are hosting a website in an Amazon S3 bucket named website as described in Hosting a Static Website on Amazon S3. Your users load the website endpoint http://website.s3-website-us-east-1.amazonaws.com. Now you want to use JavaScript on the webpages that are stored in this bucket to be able to make authenticated GET and PUT requests against the same bucket by using the Amazon S3 API endpoint for the bucket, website.s3.amazonaws.com. A browser would normally block JavaScript from allowing those requests, but with CORS you can congure your bucket to explicitly enable cross-origin requests from website.s3-website-us-east-1.amazonaws.com.

Scenario 2: Suppose that you want to host a web font from your S3 bucket. Again, browsers require a CORS check (also called a preight check) for loading web fonts. You would congure the bucket that is hosting the web font to allow any origin to make these requests.

Q42: Your mobile application includes a photo-sharing service that is expecting tens of thousands of users at launch. You will leverage Amazon Simple Storage Service (S3) for storage of the user Images, and you must decide how to authenticate and authorize your users for access to these images. You also need to manage the storage of these images. Which two of the following approaches should you use? Choose two answers from the options below

  • A. Create an Amazon S3 bucket per user, and use your application to generate the S3 URL for the appropriate content.
  • B. Use AWS Identity and Access Management (IAM) user accounts as your application-level user database, and offload the burden of authentication from your application code.
  • C. Authenticate your users at the application level, and use AWS Security Token Service (STS)to grant token-based authorization to S3 objects.
  • D. Authenticate your users at the application level, and send an SMS token message to the user. Create an Amazon S3 bucket with the same name as the SMS message token, and move the user’s objects to that bucket.


Answer- C
The AWS Security Token Service (STS) is a web service that enables you to request temporary, limited-privilege credentials for AWS Identity and Access Management (IAM) users or for users that you authenticate (federated users). The token can then be used to grant access to the objects in S3.
You can then provides access to the objects based on the key values generated via the user id.

Which of the below feature should be used when developing such a solution?

  • A. AWS DynamoDB Encryption
  • B. AWS DynamoDB Streams
  • C. AWS DynamoDB Accelerator
  • D. AWSTable Accelerator


Answer – B
DynamoDB Streams Use Cases and Design Patterns This post describes some common use cases you might encounter, along with their design options and solutions, when migrating data from relational data stores to Amazon DynamoDB. We will consider how to manage the following scenarios:

  • How do you set up a relationship across multiple tables in which, based on the value of an item from one table, you update the item in a second table?
  • How do you trigger an event based on a particular transaction?
  • How do you audit or archive transactions?
  • How do you replicate data across multiple tables (similar to that of materialized views/streams/replication in relational data stores)?

Relational databases provide native support for transactions, triggers, auditing, and replication. Typically, a transaction in a database refers to performing create, read, update, and delete (CRUD) operations against multiple tables in a block. A transaction can have only two states—success or failure. In other words, there is no partial completion. As a NoSQL database, DynamoDB is not designed to support transactions. Although client-side libraries are available to mimic the transaction capabilities, they are not scalable and cost-effective. For example, the Java Transaction Library for DynamoDB creates 7N+4 additional writes for every write operation. This is partly because the library holds metadata to manage the transactions to ensure that it’s consistent and can be rolled back before commit. You can use DynamoDB Streams to address all these use cases. DynamoDB Streams is a powerful service that you can combine with other AWS services to solve many similar problems. When enabled, DynamoDB Streams captures a time-ordered sequence of item-level modifications in a DynamoDB table and durably stores the information for up to 24 hours. Applications can access a series of stream records, which contain an item change, from a DynamoDB stream in near real time. AWS maintains separate endpoints for DynamoDB and DynamoDB Streams. To work with database tables and indexes, your application must access a DynamoDB endpoint. To read and process DynamoDB Streams records, your application must access a DynamoDB Streams endpoint in the same Region. All of the other options are incorrect since none of these would meet the core requirement.

Q46: An application has been making use of AWS DynamoDB for its back-end data store. The size of the table has now grown to 20 GB , and the scans on the table are causing throttling errors. Which of the following should now be implemented to avoid such errors?

  • A. Large Page size
  • B. Reduced page size
  • C. Parallel Scans
  • D. Sequential scans

Answer – B
When you scan your table in Amazon DynamoDB, you should follow the DynamoDB best practices for avoiding sudden bursts of read activity. You can use the following technique to minimize the impact of a scan on a table’s provisioned throughput. Reduce page size Because a Scan operation reads an entire page (by default, 1 MB), you can reduce the impact of the scan operation by setting a smaller page size. The Scan operation provides a Limit parameter that you can use to set the page size for your request. Each Query or Scan request that has a smaller page size uses fewer read operations and creates a “pause” between each request. For example, suppose that each item is 4 KB and you set the page size to 40 items. A Query request would then consume only 20 eventually consistent read operations or 40 strongly consistent read operations. A larger number of smaller Query or Scan operations would allow your other critical requests to succeed without throttling.

Q49: Your company has developed a web application and is hosting it in an Amazon S3 bucket configured for static website hosting. The users can log in to this app using their Google/Facebook login accounts. The application is using the AWS SDK for JavaScript in the browser to access data stored in an Amazon DynamoDB table. How can you ensure that API keys for access to your data in DynamoDB are kept secure?

  • A. Create an Amazon S3 role in IAM with access to the specific DynamoDB tables, and assign it to the bucket hosting your website
  • B. Configure S3 bucket tags with your AWS access keys for your bucket hosing your website so that the application can query them for access.
  • C. Configure a web identity federation role within IAM to enable access to the correct DynamoDB resources and retrieve temporary credentials
  • D. Store AWS keys in global variables within your application and configure the application to use these credentials when making requests.


Answer – C
With web identity federation, you don’t need to create custom sign-in code or manage your own user identities. Instead, users of your app can sign in using a well-known identity provider (IdP) —such as Login with Amazon, Facebook, Google, or any other OpenID Connect (OIDC)-compatible IdP, receive an authentication token, and then exchange that token for temporary security credentials in AWS that map to an IAM role with permissions to use the resources in your AWS account. Using an IdP helps you keep your AWS account secure, because you don’t have to embed and distribute long-term security credentials with your application. Option A is invalid since Roles cannot be assigned to S3 buckets Options B and D are invalid since the AWS Access keys should not be used

Amazon Cognito Streams gives developers control and insight into their data stored in Amazon Cognito. Developers can now configure a Kinesis stream to receive events as data is updated and synchronized. Amazon Cognito can push each dataset change to a Kinesis stream you own in real time. All other options are invalid since you should use Cognito Streams

Q51: You’ve developed a set of scripts using AWS Lambda. These scripts need to access EC2 Instances in a VPC. Which of the following needs to be done to ensure that the AWS Lambda function can access the resources in the VPC. Choose 2 answers from the options given below

  • A. Ensure that the subnet ID’s are mentioned when configuring the Lambda function
  • B. Ensure that the NACL ID’s are mentioned when configuring the Lambda function
  • C. Ensure that the Security Group ID’s are mentioned when configuring the Lambda function
  • D. Ensure that the VPC Flow Log ID’s are mentioned when configuring the Lambda function


Answer: A and C.
AWS Lambda runs your function code securely within a VPC by default. However, to enable your Lambda function to access resources inside your private VPC, you must provide additional VPCspecific configuration information that includes VPC subnet IDs and security group IDs. AWS Lambda uses this information to set up elastic network interfaces (ENIs) that enable your function to connect securely to other resources within your private VPC.

Q52: You’ve currently been tasked to migrate an existing on-premise environment into Elastic Beanstalk. The application does not make use of Docker containers. You also can’t see any relevant environments in the beanstalk service that would be suitable to host your application. What should you consider doing in this case?

  • A. Migrate your application to using Docker containers and then migrate the app to the Elastic Beanstalk environment.
  • B. Consider using Cloudformation to deploy your environment to Elastic Beanstalk
  • C. Consider using Packer to create a custom platform
  • D. Consider deploying your application using the Elastic Container Service


Answer – C
Elastic Beanstalk supports custom platforms. A custom platform is a more advanced customization than a Custom Image in several ways. A custom platform lets you develop an entire new platform from scratch, customizing the operating system, additional software, and scripts that Elastic Beanstalk runs on platform instances. This flexibility allows you to build a platform for an application that uses a language or other infrastructure software, for which Elastic Beanstalk doesn’t provide a platform out of the box. Compare that to custom images, where you modify an AMI for use with an existing Elastic Beanstalk platform, and Elastic Beanstalk still provides the platform scripts and controls the platform’s software stack. In addition, with custom platforms you use an automated, scripted way to create and maintain your customization, whereas with custom images you make the changes manually over a running instance. To create a custom platform, you build an Amazon Machine Image (AMI) from one of the supported operating systems—Ubuntu, RHEL, or Amazon Linux (see the flavor entry in Platform.yaml File Format for the exact version numbers)—and add further customizations. You create your own Elastic Beanstalk platform using Packer, which is an open-source tool for creating machine images for many platforms, including AMIs for use with Amazon EC2. An Elastic Beanstalk platform comprises an AMI configured to run a set of software that supports an application, and metadata that can include custom configuration options and default configuration option settings.
