Security and Compliance →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is to create a VPC endpoint for S3 and attach a bucket policy that denies access unless `aws:SourceVpce` matches the endpoint and `aws:SecureTransport` is true, while enabling S3 default encryption for at-rest protection. This configuration is correct because the bucket policy uses the `aws:SourceVpce` condition key to enforce that all traffic must originate from the specific VPC endpoint, and the `aws:SecureTransport` condition ensures encryption in transit by requiring HTTPS. Additionally, S3 default encryption automatically encrypts objects at rest using server-side encryption, satisfying the security team’s dual encryption requirement. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of how to combine bucket policy conditions with VPC endpoints, a common trap being that IAM roles alone cannot restrict access to a specific endpoint. A key memory tip is “Vpce + SecureTransport + SSE” — think of the three pillars: endpoint restriction, HTTPS enforcement, and server-side encryption.

DOP-C02 Security and Compliance Practice Question

This DOP-C02 practice question tests your understanding of security and compliance. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A company uses AWS CodePipeline to deploy a web application. The pipeline uses artifacts stored in an S3 bucket. The Security team requires that all artifacts be encrypted in transit and at rest, and that the pipeline only access the bucket using a specific VPC endpoint. Which configuration meets these requirements?

A
Configure an IAM role for CodePipeline with a policy that allows s3:GetObject and s3:PutObject, and attach a bucket policy that allows only that role
Why wrong: This does not enforce encryption or VPC endpoint restriction.
B
Create a VPC endpoint for S3 and attach a bucket policy that denies access unless aws:SourceVpce matches the endpoint and aws:SecureTransport is true, and use S3 default encryption
The bucket policy enforces HTTPS and VPC endpoint, and default encryption ensures at-rest encryption.
C
Use an S3 bucket with a lifecycle policy to expire old artifacts
Why wrong: Lifecycle policies do not address encryption or network restrictions.
D
Enable S3 block public access and use SSE-S3 encryption on the bucket
Why wrong: This does not enforce VPC endpoint restriction.

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Create a VPC endpoint for S3 and attach a bucket policy that denies access unless aws:SourceVpce matches the endpoint and aws:SecureTransport is true, and use S3 default encryption

To enforce encryption in transit and at rest and restrict to a VPC endpoint, you must configure a bucket policy that denies access unless the request uses HTTPS (for transit) and server-side encryption (for at rest), and aws:SourceVpce condition. IAM roles alone cannot enforce VPC endpoint restriction.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
