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 company wants to implement a configuration management strategy for their EC2 instances that are part of an Auto Scaling group. They need to ensure that new instances are automatically configured with the latest software packages and settings without manual intervention. Which TWO approaches meet these requirements? (Choose TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS CodeDeploy with an Auto Scaling lifecycle hook to deploy applications to new instances.
Options A and C are correct. Option A uses a bootstrapping script in the user data to install packages on launch. Option C uses AWS CodeDeploy to automatically deploy applications to new instances. Option B is incorrect because AWS Config is for compliance, not configuration management. Option D is incorrect because AWS OpsWorks is a separate service, not directly integrated with Auto Scaling groups. Option E is incorrect because Systems Manager Run Command is manual, not automatic on launch.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use AWS OpsWorks to manage configurations and associate with the Auto Scaling group.
Why it's wrong here
OpsWorks manages its own instances, not directly integrated with Auto Scaling.
✓
Use AWS CodeDeploy with an Auto Scaling lifecycle hook to deploy applications to new instances.
Why this is correct
Lifecycle hooks can trigger CodeDeploy deployments on launch.

✓
Use EC2 user data scripts to install software at launch.
Why this is correct
User data scripts run automatically on instance launch.

✗
Use AWS Config rules to enforce configuration settings.
Why it's wrong here
Config rules detect non-compliance, but do not configure instances.
✗
Use AWS Systems Manager Run Command on a schedule to apply configurations.
Why it's wrong here
Run Command is not automatic on instance launch.
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.
Trap categories for this question
Command / output trap

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.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
