SDLC Automation →hardMultiple SelectObjective-mapped

Quick Answer

The correct answer is to use AWS Secrets Manager to store the secrets and reference them in the buildspec using the 'secrets-manager' field, combined with the AWS Systems Manager Parameter Store as an alternative using the 'parameter-store' field. These services prevent sensitive data like database passwords from being exposed in build logs because CodeBuild automatically masks the resolved values when they are fetched via these dedicated fields, unlike plain-text environment variables which can be printed during build execution. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of secure secrets in CodeBuild buildspec, often appearing as a trap where candidates mistakenly choose encryption-at-rest options or assume that authorized user access is the core issue. The key distinction is that encryption at rest does not prevent secrets from being logged in plain text during the build process. Memory tip: think "fetch, don't embed"—always pull secrets from a parameter store or secrets manager using the native buildspec fields to keep them out of logs.

DOP-C02 SDLC Automation Practice Question

This DOP-C02 practice question tests your understanding of sdlc automation. 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 is using AWS CodeBuild to compile and test code. The buildspec.yml file includes a pre_build phase that installs dependencies and a build phase that runs the compilation. The tests are run in the post_build phase. The team wants to improve the security of the build process by ensuring that sensitive information such as database passwords is not exposed in the build logs. Which TWO actions should the team take? (Choose two.)

Full question →

A
Use AWS Systems Manager Parameter Store to store the secrets and reference them in the buildspec using the 'parameter-store' field.
Parameter Store can store secrets securely and references are not displayed in logs.
B
Use AWS Secrets Manager to store the secrets and reference them in the buildspec using the 'secrets-manager' field.
Secrets Manager provides secure storage and retrieval; references are not printed in logs.
C
Restrict access to the build logs by using IAM policies to only allow specific users to view them.
Why wrong: Restricting access does not prevent the secret from being present in the logs in plain text; it only limits who can see it.
D
Enable encryption at rest for the CodeBuild project's S3 logs.
Why wrong: Encryption at rest protects data while stored but does not prevent secrets from being logged in plain text.
E
Store the secrets as plain-text environment variables in the CodeBuild project.
Why wrong: Plain-text environment variables can be printed in build logs if the buildspec includes echo commands or if the build tool outputs them.

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

✓

Use AWS Systems Manager Parameter Store to store the secrets and reference them in the buildspec using the 'parameter-store' field.

Options B and D are correct. Using AWS Systems Manager Parameter Store or AWS Secrets Manager to store secrets and referencing them in the buildspec using parameter-store or secrets-manager prevents secrets from being printed in logs. Option A is wrong because environment variables in plain text can be logged. Option C is wrong because build logs are accessible to authorized users, but the issue is exposure in plain text. Option E is wrong because encryption at rest does not prevent secrets from being logged in plain text.

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

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.
