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.
A developer is using AWS CodeBuild to compile code. The build takes a long time because dependencies are downloaded each time. What can the developer do to reduce build time?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable caching in the build project to store dependencies in Amazon S3.
Option C is correct because caching dependencies in a S3 bucket allows subsequent builds to reuse them. Option A is wrong because upgrading instance type may not help if the bottleneck is network. Option B is wrong because parallel builds don't reduce single build time. Option D is wrong because multiple build environments don't reduce time.
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.
✗
Split the build into multiple parallel build actions.
Why it's wrong here
Parallel builds speed up overall pipeline, not individual build time.
✗
Use multiple build environments to distribute the work.
Why it's wrong here
Multiple environments are for different platforms, not for speeding up a single build.
✓
Enable caching in the build project to store dependencies in Amazon S3.
Why this is correct
Caching avoids re-downloading dependencies.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use a larger compute type for the build project.
Why it's wrong here
Faster instance may not reduce dependency download time.
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
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.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
