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.
A company uses AWS OpsWorks for Chef Automate. They have a stack that includes a PHP application layer. The application requires a custom PHP configuration file. The DevOps engineer creates a custom Chef cookbook with a recipe that deploys the configuration file. The recipe is assigned to the layer's Setup lifecycle event. The engineer notices that the configuration file is not being created on new instances when they are added to the layer. The cookbook is stored in a private S3 bucket. The engineer has verified that the cookbook is correctly associated with the stack. What should the engineer do to fix the issue?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure that the instance profile has permissions to read from the S3 bucket where the cookbook is stored
Option C is correct because OpsWorks requires that the cookbook be installed on the instance before the lifecycle event runs. The cookbook is in a private S3 bucket, so the instance needs permission to access it. The engineer should ensure that the stack's custom cookbooks source is configured with the correct S3 bucket and that the instance profile has permissions to read from the bucket. Option A is wrong because the recipe is assigned to the correct lifecycle event. Option B is wrong because the cookbook version is not the issue. Option D is wrong because the recipe is in the cookbook.
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.
✗
Assign the recipe to the Configure lifecycle event instead of Setup
Why it's wrong here
Setup is the correct event for initial configuration.
✗
Verify that the recipe is included in the cookbook's default.rb file
Why it's wrong here
Recipes are invoked directly, not necessarily via default.rb.
✗
Update the cookbook version to the latest
Why it's wrong here
Version is not the likely issue.
✓
Ensure that the instance profile has permissions to read from the S3 bucket where the cookbook is stored
Why this is correct
Without S3 read access, the cookbook cannot be downloaded.

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.
