- A
Use AWS CodePipeline with approval gates for security checks.
Approval gates allow security review without manual scanning.
- B
Require manual vulnerability scanning before each deployment.
Why wrong: Manual scanning is slow and inconsistent.
- C
Encrypt all container images using AWS KMS.
Why wrong: Encryption protects data at rest but does not address vulnerabilities.
- D
Integrate Amazon ECR scanning into the CI/CD pipeline.
Automated scanning finds vulnerabilities early.
- E
Implement image signing using AWS Signer.
Signing ensures image integrity and provenance.

SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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. 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 runs a containerized application on Amazon ECS with Fargate. They want to improve the security of their container images without slowing down the CI/CD pipeline. Which THREE measures should they implement?
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
✓
Use AWS CodePipeline with approval gates for security checks.
Option A is correct because AWS CodePipeline with approval gates allows you to introduce manual or automated approval steps that can enforce security checks (e.g., vulnerability scan results, policy compliance) before a container image is promoted to production. This ensures that security validation occurs without blocking the entire CI/CD pipeline—only the deployment stage is gated, preserving pipeline speed for earlier stages like build and test.
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
The trap here is that candidates may confuse 'improving security' with 'adding manual steps' (Option B) or 'encrypting images' (Option C), failing to recognize that the question explicitly requires measures that do not slow down the CI/CD pipeline, making automated, integrated solutions (scanning, signing, and gated approvals) the correct choices.
Detailed technical explanation
How to think about this question
Amazon ECR scanning (Option D) can be integrated into the CI/CD pipeline using the `aws ecr start-image-scan` API or via ECR's enhanced scanning with Amazon Inspector, which automatically triggers scans on push and returns findings that can be evaluated in a pipeline step (e.g., using `describe-image-scan-findings`). Image signing with AWS Signer (Option E) uses digital signatures to ensure image integrity and authenticity; the pipeline can verify signatures before deployment using the `aws signer describe-signing-job` or by checking the signature in the image manifest, preventing tampered images from being deployed.
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.
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
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
