- A
The buildspec has syntax errors; validate the YAML.
Why wrong: Syntax errors would cause immediate failure, not timeout.
- B
The build environment is too small; increase compute type.
Why wrong: The error is a timeout, not resource exhaustion.
- C
The source code repository is too large; use shallow clone.
Why wrong: Large repos may slow down, but timeout error points to build duration limit.
- D
The build timeout limit is exceeded; increase the timeout in CodeBuild project settings.
The default timeout is 60 minutes; extending it allows longer builds.

DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. 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 DevOps team uses AWS CodeBuild to compile code and run unit tests. The team notices that builds are failing with a timeout error after 60 minutes. What is the most likely cause and solution?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"most likely"Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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
✓
The build timeout limit is exceeded; increase the timeout in CodeBuild project settings.
The default build timeout for AWS CodeBuild is 60 minutes. When a build runs longer than this limit, it fails with a timeout error. The correct solution is to increase the timeout value in the CodeBuild project settings, which can be set up to a maximum of 8 hours (480 minutes) for on-demand compute environments.
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.
- ✗
The buildspec has syntax errors; validate the YAML.
Why it's wrong here
Syntax errors would cause immediate failure, not timeout.

The source code repository is too large; use shallow clone.
Why it's wrong here
Large repos may slow down, but timeout error points to build duration limit.
- ✓
The build timeout limit is exceeded; increase the timeout in CodeBuild project settings.
Why this is correct
The default timeout is 60 minutes; extending it allows longer builds.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse a timeout error with resource constraints (like compute size) or source code issues, but the specific 60-minute failure point is a direct indicator of the default build timeout being exceeded.
Detailed technical explanation
How to think about this question
CodeBuild's timeout is configured at the project level via the `timeoutInMinutes` parameter (or through the AWS Console). The default is 60 minutes, and the maximum is 480 minutes for on-demand environments or 120 minutes for Lambda compute. The timeout applies to the entire build lifecycle, including source download, build phases, and post-build actions. If a build consistently hits this limit, it indicates the build process itself requires more time, not that the environment is too small or the repository is too large.
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
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.
