AWS Cloud Practitioner CLF-C02 Exam
Readiness Practice Test 2026–2027 |
Comprehensive Question Bank, Answers
& Detailed Rationales
1. A company wants to deploy an application on AWS without purchasing or
maintaining physical servers. Which cloud computing benefit does this
primarily demonstrate?
A. Global reach
B. Elasticity
C. Economies of scale
D. Agility
**Answer: ** Agility
Rationale: Agility is the ability to quickly provision and use IT resources as
business requirements change. AWS allows organizations to obtain
infrastructure and services without the lengthy procurement process associated
with physical hardware.
, 2. A workload experiences unpredictable traffic spikes. The company wants
resources to increase when demand rises and decrease when demand falls.
Which AWS concept best addresses this requirement?
A. High availability
B. Elasticity
C. Fault isolation
D. Durability
**Answer: ** Elasticity
Rationale: Elasticity allows resources to dynamically scale according to
workload demand. This helps avoid paying for excessive capacity during low-
demand periods while maintaining performance during spikes.
3. Which AWS service provides resizable compute capacity in the cloud?
A. Amazon S3
B. Amazon EC2
C. Amazon DynamoDB
D. AWS Lambda
**Answer: ** Amazon EC2
Rationale: Amazon EC2 provides virtual servers with configurable compute,
memory, storage, and networking characteristics. Customers can select instance
types appropriate for their workloads.
4. A developer wants to run code in response to events without provisioning
or managing servers. Which service is most appropriate?
A. Amazon EC2
B. Amazon ECS
,C. AWS Lambda
D. Amazon Lightsail
**Answer: ** AWS Lambda
Rationale: AWS Lambda is a serverless compute service that executes code in
response to events. AWS manages the underlying servers and automatically
handles the required compute capacity.
5. A company needs object storage for images, videos, backups, and static
website assets. Which AWS service should it choose?
A. Amazon EBS
B. Amazon S3
C. Amazon EFS
D. Amazon FSx
**Answer: ** Amazon S3
Rationale: Amazon S3 is an object storage service designed for highly durable
storage of objects such as documents, images, videos, backups, and application
data.
6. Which characteristic most accurately distinguishes Amazon S3 from
Amazon EBS?
A. S3 is object storage, while EBS provides block storage
B. S3 is compute storage, while EBS is object storage
C. S3 is exclusively for databases, while EBS is for archives
D. S3 can only be accessed from on-premises environments
**Answer: ** S3 is object storage, while EBS provides block storage
, Rationale: Amazon S3 stores data as objects within buckets, whereas Amazon
EBS provides persistent block storage volumes that can be attached to Amazon
EC2 instances.
7. An organization needs a shared file system that multiple Linux EC2
instances can access concurrently. Which service is most appropriate?
A. Amazon EBS
B. Amazon S3 Glacier
C. Amazon EFS
D. Amazon DynamoDB
**Answer: ** Amazon EFS
Rationale: Amazon Elastic File System (EFS) provides managed file storage that
can be mounted concurrently by multiple compute resources, making it
appropriate for shared Linux file-system workloads.
8. Which AWS database service is a managed relational database service?
A. Amazon DynamoDB
B. Amazon RDS
C. Amazon S3
D. Amazon ElastiCache
**Answer: ** Amazon RDS
Rationale: Amazon Relational Database Service (RDS) simplifies the deployment,
operation, and scaling of supported relational database engines while AWS
manages many underlying administrative tasks.
