The correct answer is to set the deploy action's retry count to 3 in the pipeline definition. This works because CodePipeline natively supports automatic retry for transient errors at the action level, allowing you to specify a retry count directly in the pipeline structure without additional services. When a CloudFormation deployment fails due to a temporary resource limit, the action will automatically reattempt up to the configured number of times, giving the transient condition time to resolve. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this question tests your understanding of CodePipeline's built-in retry capabilities versus over-engineering with Step Functions or misapplying retries at the pipeline execution level. A common trap is assuming you need to wrap the entire pipeline in a retry loop or rely on CloudFormation's own retry logic, which does not exist for action failures. Remember the memory tip: "Action retry, not pipeline retry—keep it simple at the step level."
DOP-C02 Resilient Cloud Solutions Practice Question
This DOP-C02 practice question tests your understanding of resilient cloud 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 uses AWS CodePipeline to deploy a web application. The pipeline includes a deploy action that uses AWS CloudFormation to update a stack. The deployment occasionally fails because of a transient resource limit error. Which automatic retry strategy should a DevOps engineer implement?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set the deploy action's retry count to 3 in the pipeline definition
Option B is correct because CodePipeline supports automatic retry of actions; the retry count can be set to 3. Option A is wrong because the pipeline execution itself should not be retried entirely. Option C is wrong because CloudFormation does not have a built-in retry mechanism; it fails the action. Option D is wrong because Step Functions adds complexity and cost.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use an AWS Step Function to orchestrate the deployment with retry logic
Why it's wrong here
Unnecessary; CodePipeline already supports retry.
✓
Set the deploy action's retry count to 3 in the pipeline definition
Read the scenario before looking for a memorised answer.
✗
Modify the CloudFormation stack to include a retry policy
Why it's wrong here
CloudFormation does not support retry on resource creation.
✗
Configure the pipeline to retry the entire pipeline execution on failure
Why it's wrong here
Retrying the whole pipeline is inefficient and may cause other issues.
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

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
