- A
Use a larger build environment for the Test stage.
Why wrong: Larger environments may help but not as much as parallelism if tests are independent.
- B
Configure parallel build actions in the Test stage to run tests concurrently.
Running tests in parallel reduces the overall stage duration.
- C
Remove the Test stage and rely on post-deployment testing.
Why wrong: This skips testing, increasing risk.
- D
Move the Test stage to after deployment.
Why wrong: This does not speed up feedback; it delays testing.
Question 871 of 1,750
Speed Up Integration Tests: Parallel Actions in CodePipeline
This DOP-C02 practice question tests your understanding of sdlc automation. 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.
An organization uses AWS CodePipeline with multiple stages: Source, Build, Test, and Deploy. The Test stage runs integration tests that take 30 minutes. The team wants to speed up feedback without skipping tests. Which action should they take?
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 parallel build actions in the Test stage to run tests concurrently.
Option B is correct because running integration tests in parallel within the Test stage reduces the total wall-clock time for the test suite, speeding up feedback without skipping any tests. AWS CodePipeline supports parallel actions within a stage, allowing multiple test suites to execute concurrently, which directly addresses the goal of faster feedback while maintaining test coverage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often assume 'larger build environment' (Option A) is the universal solution for slow tests, but the DOP-C02 exam tests understanding that parallelism is the correct approach when tests are independent and the goal is to reduce elapsed time without sacrificing coverage.
Detailed technical explanation
How to think about this question
CodePipeline stages can contain multiple actions that run in parallel by default, and each action can be configured with its own build project (e.g., AWS CodeBuild). For integration tests, splitting the test suite into independent subsets (e.g., by module or endpoint) and running them as parallel actions can reduce the overall stage duration from 30 minutes to the time of the longest-running subset. This approach requires careful test design to avoid dependencies between parallel test groups, as shared resources (e.g., databases) may need isolation or locking mechanisms to prevent race conditions.
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.
