b) Availability Zones
c) Regions

Answer 8

b) Availability Zones

This is the definition of Availability Zones.

Question 9

Which of the following is NOT one of the Five Characteristics of Cloud Computing?

a) Rapid elasticity and scalability
b) Multi-tenancy and resource pooling
c) Dedicated Support Agent to help you deploy applications
d) On-demand self-service

Answer 9

c) Dedicated Support Agent to help you deploy applications

This is not one of the Five Characteristics of Cloud Computing. In the cloud, everything is self-service.

Question 10

Which are the 3 pricing fundamentals of the AWS Cloud?

a) Compute, Storage, and Data transfer in the AWS Cloud
b) Compute, Networking, and Data transfer out of the AWS Cloud
c) Compute, Storage, and Data transfer out of the AWS Cloud
d) Storage, Functions, and Data transfer in the AWS Cloud

Answer 10

c) Compute, Storage, and Data transfer out of the AWS Cloud

Compute, Storage, and data transfer out of the AWS Cloud are the 3 pricing fundamentals of the AWS Cloud.

Question 11

Which of the following is NOT an advantage of Cloud Computing?

a) Trade capital expense (CAPEX) for the operational expense (OPEX)
b) Train your employees less
c) Go global in minutes
d) Stop spending money running and maintaining data centers

Answer 11

b) Train your employess less

You must train your employees more so they can use the cloud effectively.

Question 12

AWS Regions are composed of?

a) Two or more Edge Locations
b) One or more discrete data centers
c) Two or more availability zones

Answer 12

c) Two or more availability zones

AWS Regions consist of multiple, isolated, and physically separate Availability Zones within a geographic area.

Question 13

Which of the following services has a global scope?

a) EC2
b) IAM
c) Lambda
d) Rekognition

Answer 13

b) IAM

IAM is a global service (encompasses all regions).

Question 14

What defines the distribution of responsibilities for security in the AWS Cloud?

a) AWS Pricing Fundamentals
b) The Shared Responsibility Model
c) AWS Acceptable Use Policy
d) The AWS Management Console

Answer 14

b) The Shared Responsibility Model

The Shared Responsibility Model defines who is responsible for what in the AWS Cloud.

Question 15

A company would like to benefit from the advantages of the Public Cloud but would like to keep sensitive assets in its own infrastructure. Which deployment model should the company use?

a) Private Cloud
b) Public Cloud
c) Hybrid Cloud

Answer 15

Using a Hybrid Cloud deployment model allows you to benefit from the flexibility, scalability and on-demand storage access while keeping security and performance of your own infrastructure.

c) Hybrid Cloud

Question 16

What is NOT authorized to do on AWS according to the AWS Acceptable Use Policy?

a) Building a gaming application
b) Deploying a web site
c) Run analytics on stolen content
d) Backup your data

Answer 16

c) Run analytics on stolen content

You can run analytics on AWS, but you cannot run analytics on fraudulent content. Refer to the AWS Acceptable Use Policy to see what is not authorized to do on AWS.

Question 17

What are the 5 characteristics of Cloud Computing?

Answer 17

1. Is fully on-demand self service: users can provision resources and use them without human interaction from the service provider
2. Broad network access: resources are available over the network, and can be accessed by diverse client platforms.
3. Multi-tenancy and resource pooling: Multiple customers can share the same infrastructure and applications with security and privacy; multiple customers are serviced from the same physical resources.
4. Rapid elasticity and scalability: Automatically and quckly acquire and dispose resources when needed; quickly and easily scale based on demand.
5. Measured service: usage is measured, users pay for what they have used.

Question 18

Mention the 6 advantages of Cloud Computing:

Answer 18

• Trade capital expense (CAPEX) for Operational Expense (OPEX): Pay On-Demand as customer don’t own hardware; Reduced Total Cost of Ownership and Operational Expense.
• Benefit from massive economies of scale: prices are reduced as AWS is more efficient due to large scale.
• Stop guessing capacity: Scale based on actual measured usage.
