SAA-C03 S3 Server-Side Encryption (SSE-S3) Practice Question

This SAA-C03 practice question tests your understanding of design secure architectures. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. A key principle to apply: s3 Server-Side Encryption (SSE-S3). 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 designing a secure CI/CD pipeline on AWS. Developers push code to AWS CodeCommit, which triggers AWS CodePipeline to build and deploy applications to Amazon EC2 instances running in a VPC. The security team requires that all code is scanned for secrets and vulnerabilities before deployment, and that deployment artifacts are encrypted at rest in Amazon S3. Which three steps should be taken to meet these requirements? (Choose three.)

Answer choices

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

Add a CodeBuild step in the pipeline that runs a static code analysis tool to scan for secrets and vulnerabilities.

Adding a CodeBuild step that runs static code analysis directly addresses the requirement to scan for secrets and vulnerabilities before deployment. Using AWS Secrets Manager to store secrets and retrieve them via IAM roles ensures that sensitive credentials are not hardcoded and are securely accessed during the build. For the encryption at rest requirement, configuring the S3 bucket with default SSE-S3 encryption ensures that all objects stored in the bucket are encrypted at rest. The option to enforce HTTPS only provides encryption in transit, not at rest, and thus does not meet the requirement. CloudTrail logging addresses auditing, not encryption. Public access is insecure.

Key principle: S3 Server-Side Encryption (SSE-S3)

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap is that candidates often confuse 'encryption at rest' with 'encryption in transit'. The requirement for 'encryption at rest in S3' is met by SSE-S3 default encryption, not by enforcing HTTPS. The HTTPS policy only secures data in transit, not at rest.

Detailed technical explanation

How to think about this question

Static code analysis in CodeBuild can be implemented using a buildspec.yml that invokes tools like `gitleaks` for secrets or `safety` for dependency vulnerabilities. The pipeline can be configured to fail the build if critical findings are detected, enforcing a security gate. SSE-S3 uses AES-256 encryption managed by AWS, but the question's correct encryption option is actually enforcing encryption in transit via bucket policy (HTTPS), which prevents data exposure during upload/download.

  • Static Code Analysis

TExam Day Tips

  • 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

S3 Server-Side Encryption (SSE-S3)

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.
