DOP-C02 Configuration Management and IaC Practice Question

This DOP-C02 practice question tests your understanding of configuration management and iac. 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 DevOps team is using AWS CloudFormation to manage infrastructure. They need to ensure that stack updates are reviewed and approved by a senior engineer before being executed. Which feature should they implement?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Change sets

Change sets allow you to preview the proposed changes to a CloudFormation stack before executing them. This enables a senior engineer to review and approve the changes, ensuring that only validated updates are applied. Without change sets, updates would be applied immediately without a review step.

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.

  • ✗

    Stack policies

    Why it's wrong here

    Stack policies prevent accidental updates to specific resources but do not provide a review/approval workflow.

  • ✗

    Drift detection

    Why it's wrong here

    Drift detection identifies resources that have been modified outside of CloudFormation, not a review step.

  • ✓

    Change sets

    Why this is correct

    Change sets allow you to review the proposed changes before executing a stack update.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Stack sets

    Why it's wrong here

    Stack sets enable you to create stacks across multiple accounts and regions, not for review.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse change sets with stack policies, assuming both control updates, but stack policies only protect specific resources from modification, not the update approval process itself.

Detailed technical explanation

How to think about this question

Change sets work by comparing the current stack template with a proposed template and generating a list of resource modifications, additions, or deletions. The change set is created in a 'pending' state and must be explicitly executed via the AWS CLI, SDK, or console, which enforces a manual approval gate. In real-world scenarios, teams often combine change sets with AWS Config rules or custom approval workflows using AWS Lambda to automate notifications to senior engineers.

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.

TExam Day Tips

  • 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.
