AWS CLF-C02 Sample Questions with Explanations

These original sample questions are designed to help you check how the exam topics appear in decision-style prompts. They are not taken from the live exam.

Use these sample questions as a guided self-assessment for AWS Certified Cloud Practitioner (CLF-C02) topics such as cloud value, shared responsibility, core services, security, pricing, billing, support, and governance. The prompts stay foundational but still require careful classification.

CLF-C02 foundational sample questions

Work through each prompt before opening the explanation. CLF-C02 questions usually reward the answer that identifies the AWS category and the responsibility boundary before choosing a service name.

Question 1

Topic: Shared responsibility boundary

A company stores customer files in Amazon S3. Which responsibility remains with the customer under the shared responsibility model?

• A. Maintaining the physical disks used by the S3 service.
• B. Configuring bucket permissions and protecting access to the data.
• C. Replacing failed storage hardware inside AWS data centers.
• D. Managing the network devices that connect AWS Availability Zones.

Best answer: B

Explanation: AWS secures the underlying cloud infrastructure, but customers remain responsible for their data, identities, permissions, and configurations. S3 bucket access control is a customer-side responsibility.

Why the other choices are weaker:

• A, C, and D are part of AWS’s responsibility for the cloud infrastructure.

What this tests: Distinguishing security of the cloud from security in the cloud.

Question 2

Topic: Choosing a pricing tool

A team is planning a new workload and wants to estimate monthly AWS charges before deployment. They need to adjust service quantities and compare scenarios. Which tool is the best fit?

• A. AWS Artifact.
• B. AWS Health Dashboard.
• C. AWS Pricing Calculator.
• D. AWS CloudTrail.

Best answer: C

Explanation: AWS Pricing Calculator is used to estimate costs and model service usage before deployment. It is the right tool for planning and comparing cost scenarios.

Why the other choices are weaker:

• A provides compliance reports and agreements, not workload cost estimates.
• B reports service events and account health.
• D records API activity for audit and investigation.

What this tests: Matching billing and cost-management needs to the correct AWS tool.

Question 3

Topic: Selecting durable object storage

A company needs to store static images and log files as objects. The data should be durable and accessible by applications over standard service APIs. Which AWS service best fits?

• A. Amazon EC2 Auto Scaling.
• B. AWS IAM.
• C. Amazon Route 53.
• D. Amazon S3.

Best answer: D

Explanation: Amazon S3 is object storage for files such as images, backups, logs, and static assets. The question is asking for a storage service, not compute scaling, identity, or DNS.

Why the other choices are weaker:

• A adjusts compute capacity.
• B manages identity and access.
• C provides DNS and domain routing.

What this tests: Recognizing core AWS service categories at foundational level.
