This DVA-C02 practice question tests your understanding of deployment. 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 company uses AWS CodeBuild to compile and test a Java application. The build process takes a long time because dependencies are downloaded every time. Which TWO actions can reduce build time? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable local caching in the CodeBuild project to reuse dependency files between builds.
Options A and D are correct: Caching dependencies in a local cache or in S3 reduces download time. Option B (increase compute) does not reduce dependency download. Option C (parallel builds) is for multiple builds. Option E (change runtime) is not relevant.
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.
✗
Increase the compute type of the build environment to have more CPU and memory.
Why it's wrong here
Faster compute does not reduce network download time for dependencies.
✗
Change the build runtime to a language that compiles faster.
Why it's wrong here
Changing language is not a feasible optimization.
✗
Configure the build project to run builds in parallel.
Why it's wrong here
Parallel builds do not speed up a single build.
✓
Enable local caching in the CodeBuild project to reuse dependency files between builds.
Why this is correct
Local cache stores files on the build instance for subsequent builds.

Read the scenario before looking for a memorised answer.
✓
Use Amazon S3 to cache dependencies and restore them at the start of each build.
Why this is correct
S3 caching can be used to store and retrieve dependencies quickly.

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.
