AWS All Chapters - All Review Questions
1. Which of the following describes a physical location around the world where AWS
clusters data centers?
A. Endpoint
B. Collection
C. Fleet
D. Region - ANSWER1. D. A region is a named set of AWS resources in the same
geographical area. A region comprises at least two Availability Zones. Endpoint,
Collection, and Fleet do not describe a physical location around the world where AWS
clusters data centers.
2. Each AWS region is composed of two or more locations that offer organizations the
ability to operate production systems that are more highly available, fault tolerant, and
scalable than would be possible using a single data center. What are these locations
called?
A. Availability Zones
B. Replication areas
C. Geographic districts
D. Compute centers - ANSWER2. A. An Availability Zone is a distinct location within a
region that is insulated from failures in other Availability Zones and provides
inexpensive, low-latency network connectivity to other Availability Zones in the same
region. Replication areas, geographic districts, and compute centers are not terms used
to describe AWS data center locations.
3. What is the deployment term for an environment that extends an existing on-
premises infrastructure into the cloud to connect cloud resources to internal systems?
A. All-in deployment
B. Hybrid deployment
C. On-premises deployment
D. Scatter deployment - ANSWER3. B. A hybrid deployment is a way to connect
infrastructure and applications between cloud-based resources and existing resources
that are not located in the cloud. An all-in deployment refers to an environment that
exclusively runs in the cloud. An on-premises deployment refers to an environment that
runs exclusively in an organization's data center.
4. Which AWS Cloud service allows organizations to gain system-wide visibility into
resource utilization, application performance, and operational health?
A. AWS Identity and Access Management (IAM)
B. Amazon Simple Notification Service (Amazon SNS)
C. Amazon CloudWatch
D. AWS CloudFormation - ANSWER4. C. Amazon CloudWatch is a monitoring service
for AWS Cloud resources and the applications organizations run on AWS. It allows
organizations to collect and track metrics, collect and monitor log files, and set alarms.
,AWS IAM, Amazon SNS, and AWS CloudFormation do not provide visibility into
resource utilization, application performance, and the operational health of your AWS
resources.
5. Which of the following AWS Cloud services is a fully managed NoSQL database
service?
A. Amazon Simple Queue Service (Amazon SQS)
B. Amazon DynamoDB
C. Amazon ElastiCache
D. Amazon Relational Database Service (Amazon RDS) - ANSWER5. B. Amazon
DynamoDB is a fully managed, fast, and flexible NoSQL database service for all
applications that need consistent, single-digit millisecond latency at any scale. Amazon
SQS, Amazon ElastiCache, and Amazon RDS do not provide a NoSQL database
service. Amazon SQS is a managed message queuing service. Amazon ElastiCache is
a service that provides in-memory cache in the cloud. Finally, Amazon RDS provides
managed relational databases.
6. Your company experiences fluctuations in traffic patterns to their e-commerce
website based on flash sales. What service can help your company dynamically match
the required compute capacity to the spike in traffic during flash sales?
A. Auto Scaling
B. Amazon Glacier
C. Amazon Simple Notification Service (Amazon SNS)
D. Amazon Virtual Private Cloud (Amazon VPC) - ANSWER6. A. Auto Scaling helps
maintain application availability and allows organizations to scale Amazon Elastic
Compute Cloud (Amazon EC2) capacity up or down automatically according to
conditions defined for the particular workload. Not only can it be used to help ensure
that the desired number of Amazon EC2 instances are running, but it also allows
resources to scale in and out to match the demands of dynamic workloads. Amazon
Glacier, Amazon SNS, and Amazon VPC do not provide services to scale compute
capacity automatically.
7. Your company provides an online photo sharing service. The development team is
looking for ways to deliver image files with the lowest latency to end users so the
website content is delivered with the best possible performance. What service can help
speed up distribution of these image files to end users around the world?
A. Amazon Elastic Compute Cloud (Amazon EC2)
B. Amazon Route 53
C. AWS Storage Gateway
D. Amazon CloudFront - ANSWER7. D. Amazon CloudFront is a web service that
provides a CDN to speed up distribution of your static and dynamic web content—for
example, .html, .css, .php, image, and media files—to end users. Amazon CloudFront
delivers content through a worldwide network of edge locations. Amazon EC2, Amazon
Route 53, and AWS Storage Gateway do not provide CDN services that are required to
meet the needs for the photo sharing service.
,8. Your company runs an Amazon Elastic Compute Cloud (Amazon EC2) instance
periodically to perform a batch processing job on a large and growing filesystem. At the
end of the batch job, you shut down the Amazon EC2 instance to save money but need
to persist the filesystem on the Amazon EC2 instance from the previous batch runs.
What AWS Cloud service can you leverage to meet these requirements?
A. Amazon Elastic Block Store (Amazon EBS)
B. Amazon DynamoDB
C. Amazon Glacier
D. AWS CloudFormation - ANSWER8. A. Amazon EBS provides persistent block-level
storage volumes for use with Amazon EC2 instances on the AWS Cloud. Amazon
DynamoDB, Amazon Glacier, and AWS CloudFormation do not provide persistent
block-level storage for Amazon EC2 instances. Amazon DynamoDB provides managed
NoSQL databases. Amazon Glacier provides lowcost archival storage. AWS
CloudFormation gives developers and systems administrators an easy way to create
and manage a collection of related AWS resources.
9. What AWS Cloud service provides a logically isolated section of the AWS Cloud
where organizations can launch AWS resources in a virtual network that they define?
A. Amazon Simple Workflow Service (Amazon SWF)
B. Amazon Route 53
C. Amazon Virtual Private Cloud (Amazon VPC)
D. AWS CloudFormation - ANSWER9. C. Amazon VPC lets organizations provision a
logically isolated section of the AWS Cloud where they can launch AWS resources in a
virtual network that they define. Amazon SWF, Amazon Route 53, and AWS
CloudFormation do not provide a virtual network. Amazon SWF helps developers build,
run, and scale background jobs that have parallel or sequential steps. Amazon Route
53 provides a highly available and scalable cloud Domain Name System (DNS) web
service. Amazon CloudFormation gives developers and systems administrators an easy
way to create and manage a collection of related AWS resources.
10. Your company provides a mobile voting application for a popular TV show, and 5 to
25 million viewers all vote in a 15-second timespan. What mechanism can you use to
decouple the voting application from your back-end services that tally the votes?
A. AWS CloudTrail
B. Amazon Simple Queue Service (Amazon SQS)
C. Amazon Redshift
D. Amazon Simple Notification Service (Amazon SNS) - ANSWER10. B. Amazon SQS
is a fast, reliable, scalable, fully managed message queuing service that allows
organizations to decouple the components of a cloud application. With Amazon SQS,
organizations can transmit any volume of data, at any level of throughput, without losing
messages or requiring other services to be always available. AWS CloudTrail records
AWS API calls, and Amazon Redshift is a data warehouse, neither of which would be
useful as an architecture component for decoupling components. Amazon SNS
provides a messaging bus complement to Amazon SQS; however, it doesn't provide the
decoupling of components necessary for this scenario.

pre-allocated.
