The answer is to use the Skip accounts option to temporarily exclude failing accounts during the StackSet update. This is correct because AWS CloudFormation StackSets provides a built-in mechanism to handle resource conflicts by allowing you to skip specific accounts or regions where the update fails, enabling the rest of the deployment to proceed without disruption. Once the failing accounts are isolated, you can resolve the underlying conflict—such as a resource name collision or a dependency issue—and then retry the update on those accounts individually. On the AWS Certified DevOps Engineer Professional DOP-C02 exam, this scenario tests your understanding of StackSet operational best practices, particularly the ability to manage partial failures without manual intervention or data loss. A common trap is assuming you must delete the conflicting resource or recreate the entire stack set, but the Skip accounts option preserves existing resources and minimizes downtime. Memory tip: think "Skip and fix, don't nix"—you bypass the failure to fix it later, not delete or restart the whole deployment.
DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. 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.
An organization uses AWS CloudFormation StackSets to deploy resources across multiple accounts and regions. They need to update a stack set with a new template version. The update fails in some accounts due to a resource conflict. What is the BEST way to resolve the conflict and complete the update?
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
✓
Use the 'Skip accounts' option to temporarily exclude failing accounts, then fix and retry.
Option C is correct because StackSets allows skipping accounts or regions that fail, and the engineer can retry later. Option A is incorrect because manual deletion may cause data loss. Option B is incorrect because changing the template may not resolve the conflict. Option D is incorrect because recreating the stack set is disruptive.
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.
✗
Delete the stack set and recreate it with the new template.
Why it's wrong here
This is disruptive and may cause downtime.
✗
Manually delete the conflicting resources in the failing accounts and retry the update.
Why it's wrong here
Deleting resources may cause data loss and is not automated.
✗
Modify the CloudFormation template to ignore the conflicting resources using a condition.
Why it's wrong here
Conditions cannot resolve resource conflicts.
✓
Use the 'Skip accounts' option to temporarily exclude failing accounts, then fix and retry.
Why this is correct
StackSets allows skipping specific accounts or regions during updates.

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.
