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.
Refer to the exhibit. A developer tried to create a CloudFormation stack that includes an EC2 instance. The stack creation failed and rolled back. What should the developer do to get more details about the failure?
Review the CloudFormation template syntax.
Why wrong: Syntax errors would cause a different failure.
Use the `detect-stack-drift` command.
Why wrong: Drift detection is for existing resources.
Run `aws cloudformation describe-stack-events` for the stack.
Stack events provide detailed error messages.
Update the stack with the same template to see the error.
Why wrong: Update will fail again.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Run `aws cloudformation describe-stack-events` for the stack.
Option C is correct. The `aws cloudformation describe-stack-events` command lists events for the stack, including status reason messages that detail why the creation failed. Option A (reviewing template syntax) is not the most direct way to get failure details; the events already capture errors. Option B (`detect-stack-drift`) is used to detect changes from the intended template, not to diagnose creation failures. Option D (updating with the same template) would attempt to update a failed stack, but the events from the original creation provide the needed information without additional risks.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Review the CloudFormation template syntax.
Why it's wrong here
Syntax errors would cause a different failure.
Use the `detect-stack-drift` command.
Why it's wrong here
Drift detection is for existing resources.
Run `aws cloudformation describe-stack-events` for the stack.
Why this is correct
Stack events provide detailed error messages.
Related concept
Read the scenario before looking for a memorised answer.
Update the stack with the same template to see the error.
Why it's wrong here
Update will fail again.
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.
