This DOP-C02 practice question tests your understanding of sdlc automation. 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.
A company uses AWS CloudFormation to manage infrastructure. The DevOps team wants to deploy a stack across multiple accounts using AWS CodePipeline. Which approach is BEST for automating cross-account deployments?
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 a single pipeline in the management account with IAM roles that assume cross-account roles.
Option D is correct because cross-account CodePipeline uses a KMS key and IAM roles in each account. Option A is wrong because cross-account roles are needed. Option B is wrong because CloudFormation StackSets are for multiple regions/accounts but not directly integrated with CodePipeline. Option C is wrong because separate pipelines in each account increase management overhead.
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.
✗
Use AWS CloudFormation StackSets to deploy the stack across accounts.
Why it's wrong here
StackSets do not integrate with CodePipeline stages directly.
✗
Create a separate pipeline in each account and trigger them manually.
Why it's wrong here
Manual triggers are not automated.
✓
Use a single pipeline in the management account with IAM roles that assume cross-account roles.
Why this is correct
This is the standard pattern for cross-account pipelines.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use an S3 bucket with cross-account access and Lambda to invoke CloudFormation.
Why it's wrong here
This is a custom solution; CodePipeline natively supports cross-account.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
