- A
The build environment has a network timeout when accessing external dependencies.
Why wrong: Network timeout causes 'connection timeout' errors, not file not found.
- B
The buildspec.yml file references a file or directory that does not exist in the source code.
The error 'No such file or directory' indicates the build process cannot find a specified file.
- C
The IAM role for CodeBuild does not have permissions to access the source repository.
Why wrong: Insufficient permissions cause authentication errors, not file not found.
- D
The build environment does not have the required environment variables set.
Why wrong: Missing environment variables cause 'undefined variable' errors, not file not found.
Question 943 of 1,616
CodeBuild No Such File or Directory Error
This DVA-C02 practice question tests your understanding of deployment. 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 developer is using AWS CodeBuild to compile and test code. The build phase fails with the error: 'BUILD_FAILED: Error: No such file or directory.' What is the most likely cause?
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 buildspec.yml file references a file or directory that does not exist in the source code.
Option B is correct because the error 'No such file or directory' indicates that the build process is trying to access a file or directory that does not exist in the source code, typically due to an incorrect path in the buildspec.yml file. Option A is incorrect because a network timeout would produce a different error (e.g., 'Connection timed out'). Option C is incorrect because insufficient IAM permissions would result in an 'Access Denied' error, not a file not found error. Option D is incorrect because missing environment variables would cause errors related to undefined variables, not file not found.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
