The correct answer is that the stack creation failed and has been rolled back, leaving no resources remaining. This is because the ROLLBACK_COMPLETE stack status in AWS CloudFormation indicates that the stack creation process encountered a failure, and CloudFormation has automatically cleaned up all resources that were provisioned during the attempted creation. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this status is a common distractor designed to test your understanding of the full lifecycle of stack operations—specifically the difference between a failed creation rollback and a failed update rollback. A frequent trap is confusing ROLLBACK_COMPLETE with UPDATE_ROLLBACK_COMPLETE, which only applies to update operations. Remember the memory tip: if you see “ROLLBACK” without “UPDATE,” it always refers to a failed creation, not a modification.
DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Network Topology
A DevOps engineer runs the command shown in the exhibit. The output shows the stack status as ROLLBACK_COMPLETE. Which statement best describes the current state of the stack?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The stack creation failed and has been rolled back. No resources remain.
Option B is correct because ROLLBACK_COMPLETE means the stack creation failed and rolled back, leaving no resources. Option A is wrong because that would be CREATE_COMPLETE. Option C is wrong because UPDATE_ROLLBACK_COMPLETE is for updates. Option D is wrong because ROLLBACK_IN_PROGRESS is the intermediate state.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The stack was created successfully and is in a steady state.
Why it's wrong here
ROLLBACK_COMPLETE indicates failure, not success.
✗
The stack update failed and has been rolled back to the previous state.
Why it's wrong here
The event is for a stack creation, not an update.
✗
The stack is currently in the process of rolling back after a failed creation.
Why it's wrong here
ROLLBACK_IN_PROGRESS would indicate ongoing rollback.
✓
The stack creation failed and has been rolled back. No resources remain.
Why this is correct
ROLLBACK_COMPLETE means all resources were cleaned up after failure.

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.

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.
