Question 1: Microsoft Office 365 is an example of which cloud deployment model?

A. PaaS

B. IaaS

C. CASB

D. SaaS

Answer1:

Notes:

Software as a service (SaaS) allows users to connect to and use cloud-based apps over the internet. Common examples are email, calendar, and office tools, such as Microsoft Office 365.

Reference1: SAAS

Question 2: You have an on-premises application that processes incoming Simple Message Submission Service (SMSS) queue messages and records the data to a log file. You migrate this application to an Azure function app. What kind of cloud service would this be considered?

A. Software-as-a-Service (SaaS)

B. Infrastructure-as-a-Service (IaaS)

C. Serverless

D. Platform-as-a-Service (PaaS)

Answer2:

Notes2:

Serverless computing is the abstraction of servers, infrastructure, and operating systems. When you build serverless apps, you don’t need to provision and manage any servers, so you don't have to worry about infrastructure. Serverless computing is driven by the reaction to events and triggers happening in near-real time in the cloud.

Reference2: Platform-as-a-Service (PaaS)

Question 3: Define “economy of scale”.

A. Spending money on products or services now and being billed for them now. You can deduct this expense from your tax bill in the same year.

B. Spending money on physical infrastructure up front, and then deducting that expense from your tax bill over time.

C. Prices for individual resources and services are provided so you can predict how much you will spend in a given billing period based on your expected usage.

D. The ability to do things more efficiently or at a lower cost per unit when operating at a larger scale.

Answer 3:

Notes 3:

Cloud providers such as Microsoft, Google, and Amazon are large businesses that leverage the benefits of economies of scale and then pass the savings on to their customers.

Reference3: Cloud: Economies at scale

Question 4: Which of the following are characteristic of private clouds?

A. Lower costs

B. High scalability

C. Improved security

D. Limited flexibility

Answer 4:

B and C

Notes 4:

Private clouds still afford the scalability and efficiency of a public cloud. Resources are purchased and available to meet your business needs.

Video for reference: The Private Cloud Model

Because resources are not shared with others, private clouds provide higher levels of control and security.

Reference 4: The private cloud model

Question 5: Which of the following Azure solutions allows you to geographically cache and distribute high-bandwidth content, such as streaming videos, to users in different parts of the world?

Question 7: Select the concept that is defined as ensuring that servers are available if a single data center goes offline.

A. Scalability

B. Fault tolerance

C. Elasticity

D. Agility

Answer 7:

Notes 7:

Fault tolerance is the property that enables a system to continue operating properly in the event of the failure of one or more of its components. In Azure, it refers to ensuring that a portion of the production systems are available online (via a failover cluster, available set, or available zone) if a subset of the system components (or an entire data center) goes offline.

Reference 7: Fault Tolerance

Question 8: In regards to comparing Public Cloud and Private Cloud, which of these best describe the characteristics of a Public Cloud?

A. No-upfront costs

B. More control over the security

C. Less reliability

D. Less maintenance

Answer 8:

A and D

Notes 8

The public cloud provides a pay-as-you-go pricing model which can lead to lower costs than those in private cloud solutions where capital expenditures are high.

The public cloud provides agility to provision and de-provision resources quickly with far less maintenance than that of private cloud solutions.

Reference 8: Pay as you go

Question 9: Which of the following are considered capital expenditures (CapEx)?

A. Storage area network

B. Cloud-based virtual machine

C. Office 365 licenses

D. Hyper-V host server

Answer 9:

A and D

Notes 9:

Storage costs are typically considered CapEx and include storage hardware components and the cost of supporting them. Depending on the application and level of fault tolerance, centralized storage can be expensive.

Server costs are considered CapEx and include all server hardware components and the cost of supporting them. When purchasing servers, make sure to design for fault tolerance and redundancy (e.g., server clustering, redundant power supplies, and uninterruptible power supplies). When a server needs to be replaced or added to a data center, you need to pay for the computer. This can affect your immediate cash flow because you must pay for the server up front.
