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 troubleshooting a deployment failure in AWS CodePipeline. The deploy stage uses the above IAM policy for the service role. The pipeline fails when trying to update the Elastic Beanstalk environment. 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 the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The policy restricts the UpdateEnvironment action to a specific environment ARN, but the pipeline is updating a different environment.
Option C is correct because the policy allows 'UpdateEnvironment' only on a specific environment ARN, but the pipeline may be trying to update a different environment (e.g., if the environment name changed). Option A is wrong because 'DeleteEnvironment' is denied but not used. Option B is wrong because 'DescribeEnvironmentResources' is allowed. Option D is wrong because 'DeleteEnvironment' denial does not affect updates.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
The policy restricts the UpdateEnvironment action to a specific environment ARN, but the pipeline is updating a different environment.
Why this is correct
The resource ARN must match the environment being updated.
Clue confirmation

✗
The policy does not allow DescribeEnvironmentResources, which is required for the deployment.
Why it's wrong here
It is allowed.
✗
The policy denies all actions on the environment, preventing the update.
Why it's wrong here
It only denies DeleteEnvironment.
✗
The policy denies DeleteEnvironment, which is required for the update.
Why it's wrong here
DeleteEnvironment is not needed for updates.
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.
