- A
Use Amazon CloudWatch Alarms to trigger an AWS Lambda function that restarts the pipeline.
Why wrong: This adds unnecessary complexity; CodePipeline already has built-in retry capabilities.
- B
Modify the CodeBuild project to run integration tests after deployment.
Why wrong: Smoke tests do not address the capacity failure during deployment.
- C
Add a manual approval step before the deploy stage to verify capacity.
Why wrong: Manual approval requires human intervention and is not operationally efficient.
- D
Configure the ECS service to automatically scale down the desired count on deployment failure.
Why wrong: Scaling down would reduce capacity, exacerbating the issue.
- E
Add a retry action in the CodePipeline stage for the ECS deployment.
Correct because CodePipeline supports retry actions that automatically retry the stage on failure, reducing operational overhead.
Quick Answer
The answer is to add a retry action in the CodePipeline stage for the ECS deployment. This is the most operationally efficient solution because CodePipeline’s built-in retry mechanism automatically re-runs the failed deploy action when the target group has insufficient capacity, eliminating the need for manual intervention or custom automation. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this question tests your understanding of CodePipeline’s native failure handling features versus over-engineered alternatives; a common trap is choosing a CloudWatch Alarm and Lambda solution, which adds unnecessary complexity and latency when a simple retry action suffices. Remember that for transient infrastructure failures like capacity shortages, the platform’s own retry capability is always more efficient than building external triggers. Memory tip: “Retry is the built-in safety net—don’t build a custom ladder.”
SAP-C02 Continuous Improvement for Existing Solutions Practice Question
This SAP-C02 practice question tests your understanding of continuous improvement for existing solutions. 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 CodePipeline to automate deployments of a web application. The deployment to an Amazon ECS cluster often fails during the 'Deploy' stage due to insufficient capacity in the target group. The operations team wants to improve the pipeline to automatically handle such failures without manual intervention. Which solution is MOST operationally efficient?
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 retry action in the CodePipeline stage for the ECS deployment.
Option C is correct because configuring CodePipeline with a manual approval action that retries on failure would require manual intervention, which is not operationally efficient. Option A is correct because adding a retry action in the pipeline stage automatically retries the deployment on failure. Option B is wrong because scaling down the ECS service would reduce capacity, making the problem worse. Option D is wrong because modifying the CodeBuild project to run smoke tests does not address capacity failures. Option E is wrong because using CloudWatch Alarms to trigger a Lambda function adds complexity and latency compared to a built-in retry mechanism.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
