AWS All Chapters - All Review Questions
And Answers 2025
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 - Answer - 1. 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 - Answer - 2. 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 - Answer - 3. 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 - Answer - 4. 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) - Answer - 5. 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) - Answer - 6. 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 - Answer - 7. 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 - Answer - 8. 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 - Answer - 9. 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) - Answer - 10. 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.
1. In what ways does Amazon Simple Storage Service (Amazon S3) object storage differ from block and
file storage? (Choose 2 answers)
A. Amazon S3 stores data in fixed size blocks.
B. Objects are identified by a numbered address.
C. Objects can be any size.
D. Objects contain both data and metadata.
E. Objects are stored in buckets. - Answer - 1. D, E. Objects are stored in buckets, and objects contain
both data and metadata.
2. Which of the following are not appropriates use cases for Amazon Simple Storage Service (Amazon
S3)? (Choose 2 answers)
A. Storing web content
B. Storing a file system mounted to an Amazon Elastic Compute Cloud (Amazon EC2) instance
