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 runs a production e-commerce platform on AWS. The architecture includes an Application Load Balancer (ALB) distributing traffic across EC2 instances in an Auto Scaling group. The application uses a custom configuration stored in an S3 bucket. The DevOps team uses AWS CodeDeploy to deploy application updates. Recently, a deployment failed because new instances launched by the Auto Scaling group did not have the latest configuration from S3. The team had manually updated the configuration in S3 but the deployment did not pull the new version. The team wants to ensure that all instances always have the latest configuration at launch. Current setup: The Auto Scaling group uses a launch template that specifies an IAM instance profile with permissions to read from S3. The user data script runs at launch to download configuration from S3. However, the user data script is static and does not account for configuration updates. The team wants a solution that automatically applies configuration changes to both existing and new instances without manual intervention.

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

Clue: "always"
Why it matters: Absolute qualifier. An answer using 'always' is only correct if there are genuinely no exceptions — absolute statements are often wrong in networking.

A
Use AWS Config with a custom rule to detect instances that do not have the latest configuration and trigger a Lambda function to update them.
Why wrong: Config is reactive and not designed for proactive configuration management.
B
Update the launch template with a new user data script that always fetches the latest configuration from S3. Then, update the Auto Scaling group to use the new launch template version.
Why wrong: This only affects new instances, not existing ones.
C
Configure AWS CodeDeploy to deploy the configuration to all instances whenever the S3 object is updated, using an S3 event notification.
Why wrong: CodeDeploy does not automatically run on instance launch without a lifecycle hook.
D
Use AWS Systems Manager State Manager to associate a document that runs on all instances to fetch the latest configuration from S3 on a schedule and at instance startup.
State Manager can enforce configuration on both existing and new instances.

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

✓

Use AWS Systems Manager State Manager to associate a document that runs on all instances to fetch the latest configuration from S3 on a schedule and at instance startup.

Option B is correct because AWS Systems Manager State Manager can enforce configuration on instances, pull the latest config from S3, and apply it to both existing and new instances. Option A is incorrect because updating the user data script in the launch template only affects new instances, not existing ones. Option C is incorrect because CodeDeploy does not run at instance launch unless triggered by a lifecycle hook, and it requires additional setup. Option D is incorrect because AWS Config is for compliance, not for pushing configurations.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.
