Sample Quiz:

Practice Quiz 1:

A finance company is storing paid invoices in an Amazon S3 bucket. After the invoices are uploaded, an AWS Lambda function uses Amazon Textract to process the PDF data and persist the data to Amazon DynamoDB. Currently, the Lambda execution role has the following S3 permission:

{

    “Version”: “2012-10-17”,

    “Statement”: [

        {

            “Sid”: “ExampleStmt”,

            “Action”: [“s3:*”],

            “Effect”: “Allow”,

            “Resource”: [“*”]

        }

    ]

}

The company wants to correct the role permissions specific to Amazon S3 according to security best practices.

Which solution will meet these requirements?

• Append “s3:GetObject” to the Action. Append the bucket name to the Resource.

• Modify the Action to be “s3:GetObjectAttributes.” Modify the Resource to be only the bucket name.

• Append “s3:GetObject” to the Action. Modify the Resource to be only the bucket ARN.

• Modify the Action to be: “s3:GetObject.” Modify the Resource to be only the bucket ARN.

Practice Quiz 1 – Correct Answer: D. 

According to the principle of least privilege, permissions should apply only to what is necessary. The Lambda function needs only the permissions to get the object. Therefore, this solution has the most appropriate modifications.

Practice Quiz 2:

A data engineer is designing an application that will transform data in containers managed by Amazon Elastic Kubernetes Service (Amazon EKS). The containers run on Amazon EC2 nodes. Each containerized application will transform independent datasets and then store the data in a data lake. Data does not need to be shared to other containers. The data engineer must decide where to store data before transformation is complete.

Which solution will meet these requirements with the LOWEST latency?

• Containers should use an ephemeral volume provided by the node’s RAM.

• Containers should establish a connection to Amazon DynamoDB Accelerator (DAX) within the application code.

• Containers should use a PersistentVolume object provided by an NFS storage.

• Containers should establish a connection to Amazon MemoryDB for Redis within the application code.

Practice Quiz 2 – Correct Answer: A. 

Amazon EKS is a container orchestrator that provides Kubernetes as a managed service. Containers run in pods. Pods run on nodes. Nodes can be EC2 instances, or nodes can use AWS Fargate. Ephemeral volumes exist with the pod’s lifecycle. Ephemeral volumes can access drives or memory that is local to the node. The data does not need to be shared, and the node provides storage. Therefore, this solution will have lower latency than storage that is external to the node.
