- A
Create a separate CodeBuild project to run npm install.
Why wrong: Creating a separate CodeBuild project does not resolve the npm cache integrity issue; the error will persist in the new project.
- B
Add 'npm cache verify' to the pre_build phase before 'npm install'.
Adding 'npm cache verify' before 'npm install' checks and repairs the cache, fixing the EINTEGRITY error without compromising security.
- C
Add 'npm config set registry http://registry.npmjs.org/' to use HTTP.
Why wrong: Switching to HTTP registry (http://registry.npmjs.org/) disables HTTPS integrity checks, which compromises security.
- D
Use 'npm install --prefer-offline' to avoid fetching from registry.
Why wrong: Using 'npm install --prefer-offline' avoids fetching from the registry but still uses the local cache, which may contain the corrupted data causing the integrity error.
Fixing npm EINTEGRITY Error in CodeBuild
This DVA-C02 practice question tests your understanding of development with aws services. 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.
An organization uses AWS CodeBuild to run tests for a Node.js application. The build environment is Linux. The buildspec.yml includes a pre_build phase that runs 'npm install'. Occasionally, the build fails with an error 'npm ERR! code EINTEGRITY'. The developer wants to resolve this issue without compromising security. Which action should be taken?
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
Add 'npm cache verify' to the pre_build phase before 'npm install'.
The EINTEGRITY error occurs when npm's integrity check fails due to a corrupted cache. Adding 'npm cache verify' before 'npm install' verifies and cleans the cache, resolving the issue without compromising security. Option A is incorrect because creating a separate CodeBuild project does not address the cache integrity issue. Option C is incorrect because switching to HTTP registry disables HTTPS integrity checks, compromising security. Option D is incorrect because 'npm install --prefer-offline' avoids fetching from the registry but still uses the potentially corrupted local cache.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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 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.
