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.
A company is using AWS CodeDeploy to deploy an application to an Auto Scaling group. The deployment fails with 'The overall deployment failed because too many individual instances failed deployment, too few healthy instances are available for deployment, or some instances in your deployment group are experiencing problems.' The developer wants to identify the specific error on a failed instance. Which AWS CLI command should the developer use?
aws deploy get-deployment
Why wrong: Incorrect: Provides overall deployment summary, not per-instance.
aws deploy get-deployment-instance
Correct: Provides detailed status and error for a specific instance.
aws deploy list-deployments
Why wrong: Incorrect: Lists deployment IDs.
aws deploy list-deployment-instances
Why wrong: Incorrect: Only lists instance IDs, not error details.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
aws deploy get-deployment-instance
Option D is correct because 'aws deploy get-deployment-instance' provides detailed information about a specific instance deployment. Option A is wrong because 'list-deployment-instances' only lists IDs. Option B is wrong because 'get-deployment' gives overall deployment info. Option C is wrong because 'list-deployments' lists deployments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
