DOP-C02 Configuration Management and IaC Practice Question
This DOP-C02 practice question tests your understanding of configuration management and iac. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 engineer is using AWS OpsWorks for configuration management. They need to ensure that custom recipes are applied to all instances in a layer in a specific order. What should the engineer do?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Assign the recipes to the appropriate lifecycle events in the layer configuration.
AWS OpsWorks uses lifecycle events (Setup, Configure, Deploy, Undeploy, Shutdown) to control when custom recipes run on instances within a layer. By assigning recipes to the appropriate lifecycle events in the layer configuration, the engineer ensures they execute in the defined order for that event across all instances in the layer, which is the native mechanism for ordering in OpsWorks.
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 recipes to the appropriate lifecycle events in the layer configuration.
Why this is correct
Lifecycle events allow ordered execution of recipes.
Related concept
Read the scenario before looking for a memorised answer.
✗
Use AWS CloudFormation Init with cfn-init to order the scripts.
Why it's wrong here
CloudFormation Init is a different service and not integrated with OpsWorks.
✗
Include all recipes in a single wrapper recipe and use include_recipe with the desired order.
Why it's wrong here
This does not guarantee order across instances in the layer.
✗
Add the recipes to the instance's user data script.
Why it's wrong here
User data runs before OpsWorks agent, so recipes cannot be ordered.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse OpsWorks lifecycle events with Chef's include_recipe directive, assuming that ordering within a wrapper recipe is sufficient, when OpsWorks actually enforces order through lifecycle event assignments.
Detailed technical explanation
How to think about this question
Under the hood, OpsWorks maps each lifecycle event to a Chef run list that executes assigned recipes in the order they appear in the layer configuration. The Setup event runs once at instance boot, Configure runs on every instance change, and Deploy runs during app deployment, ensuring recipes are applied consistently. A real-world scenario is a multi-tier application where database initialization recipes must run before application server recipes; assigning them to the Setup event in the correct order guarantees this dependency is met across all instances.

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.
