- A
Use Amazon CloudWatch to monitor the build and automatically restart it if it times out.
Why wrong: Incorrect. Using Amazon CloudWatch to restart a timed-out build does not increase resources or change the timeout. It merely retries with the same limitations.
- B
Use AWS Lambda instead of CodeBuild, as it can run up to 15 minutes.
Why wrong: Incorrect. AWS Lambda has a maximum execution time of 15 minutes and limited memory/CPU compared to CodeBuild. It is not designed for integration tests that require large resources and long runtimes.
- C
Select a larger instance type in the CodeBuild project configuration, such as 'BUILD_GENERAL1_LARGE'.
Correct. Selecting a larger compute type (e.g., BUILD_GENERAL1_LARGE) in the CodeBuild project configuration increases memory and CPU. The timeout can be adjusted in the same project settings or via AWS CLI. This directly addresses both requirements.
- D
Modify the buildspec.yml file to include 'compute-type' and 'timeout-in-minutes' overrides.
Why wrong: Incorrect. The buildspec.yml does not support a 'compute-type' field or a 'timeout-in-minutes' override for compute resources. Compute type is a project-level setting, and timeout overrides are only available via environment variables or the project configuration, not in buildspec.yml.
Increasing CodeBuild Resources and Timeout via buildspec.yml Overrides
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. A key principle to apply: aWS CodeBuild compute type. 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 CodeBuild to run integration tests. The tests require a large amount of memory and CPU, and they often timeout after the default 60 minutes. What is the MOST efficient way to increase the timeout and allocate more resources?
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
Select a larger instance type in the CodeBuild project configuration, such as 'BUILD_GENERAL1_LARGE'.
Option C is correct because in AWS CodeBuild, the compute type (e.g., BUILD_GENERAL1_LARGE) is a project-level configuration, not a buildspec override. To increase memory and CPU, you must select a larger compute type in the CodeBuild project settings. Additionally, the timeout can be increased in the project configuration or via the AWS CLI/API, not in the buildspec.yml. This approach is the most efficient and reliable way to allocate more resources and extend the timeout.

- ✗
Modify the buildspec.yml file to include 'compute-type' and 'timeout-in-minutes' overrides.
Why it's wrong here
Incorrect. The buildspec.yml does not support a 'compute-type' field or a 'timeout-in-minutes' override for compute resources. Compute type is a project-level setting, and timeout overrides are only available via environment variables or the project configuration, not in buildspec.yml.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap is that candidates may think buildspec.yml can override compute type, but in reality compute type is a project-level setting. Many incorrectly believe the buildspec 'timeout-in-minutes' field exists for overall build timeout, but it only applies to individual phases. The correct approach is to modify the project configuration.
Detailed technical explanation
How to think about this question
Under the hood, CodeBuild uses build environments backed by EC2 instances; the compute-type field maps to specific instance families (e.g., BUILD_GENERAL1_LARGE corresponds to a 7 GB RAM, 4 vCPU instance). The timeout-in-minutes override in buildspec.yml takes precedence over the project-level timeout, allowing per-build flexibility. In real-world scenarios, teams often use this override for integration tests that require burstable performance, while keeping the project default for standard builds.

- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
AWS CodeBuild compute type
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.
