- A
Configure the source action to trigger on all branches and add a manual approval step before the build stage.
Why wrong: This triggers builds for all branches and does not restrict deployments to production.
- B
Configure the source action with a branch filter for main, and add a manual approval step before the build stage.
Why wrong: Manual approval should be before the production deploy stage, not before build.
- C
Use a branch filter on the build action to run only for the main branch, and add a manual approval step before the deploy stage.
Why wrong: Branch filters should be on the source action, not the build action.
- D
Configure the source action with a branch filter for main, and add a manual approval step before the production deployment stage.
This ensures builds only on main pushes and requires approval before production deployment.
DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 development team is using AWS CodeCommit to store source code and AWS CodePipeline to automate builds and deployments. The team wants to ensure that builds and tests are triggered only when code is pushed to specific branches, and that manual approval is required before deploying to production. Which CodePipeline configuration should the team 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
Configure the source action with a branch filter for main, and add a manual approval step before the production deployment stage.
Option D is correct because CodePipeline source actions support branch filters that restrict which Git branches trigger the pipeline. By filtering on 'main', only pushes to that branch initiate the pipeline. Adding a manual approval step before the production deployment stage ensures that no code reaches production without explicit human sign-off, meeting both requirements precisely.
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.
- ✗
Configure the source action to trigger on all branches and add a manual approval step before the build stage.
Why it's wrong here
This triggers builds for all branches and does not restrict deployments to production.

Configure the source action with a branch filter for main, and add a manual approval step before the build stage.
Why it's wrong here
Manual approval should be before the production deploy stage, not before build.
- ✗
Use a branch filter on the build action to run only for the main branch, and add a manual approval step before the deploy stage.
Why it's wrong here
Branch filters should be on the source action, not the build action.
- ✓
Configure the source action with a branch filter for main, and add a manual approval step before the production deployment stage.
Why this is correct
This ensures builds only on main pushes and requires approval before production deployment.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse where branch filters can be applied (source action only) and where manual approval should be placed (before the production deploy stage, not before build), leading them to select options that filter incorrectly or place approval at the wrong stage.
Detailed technical explanation
How to think about this question
CodePipeline source actions use a 'Branch' configuration field that accepts a single branch name or a wildcard pattern (e.g., 'main'). When a push event occurs, CodePipeline compares the branch name against this filter; only matching branches trigger the pipeline execution. Manual approval actions are added as a stage with an 'Approval' action type, which pauses the pipeline until an authorized IAM user or role approves or rejects the transition. This design ensures that the pipeline can enforce separation of concerns between CI (continuous integration) and CD (continuous deployment) without requiring custom scripting.
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.
