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 manages a fleet of EC2 instances using AWS Systems Manager State Manager. They have a State Manager association that ensures a specific software package is installed on all instances. Recently, they noticed that some instances are reporting the association as 'Success' even though the software is not installed. The association uses a custom document that runs a script to install the package. The engineer checks the association execution history and sees that the script exited with code 0 on those instances. What is the most likely cause?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The script does not check the exit code of the installation command and always returns 0.
Option B is correct because the script may exit with code 0 even if installation fails, making State Manager think it succeeded. Option A is wrong because compliance reporting is not the issue. Option C is wrong because the association is running. Option D is wrong because the script ran.
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.
✗
The association is not targeting those instances.
Why it's wrong here
The association ran on them, so they are targeted.
✗
The instances are not configured to send compliance data to Systems Manager.
Why it's wrong here
State Manager captures output regardless of compliance settings.
✗
The instances do not have the SSM Agent installed.
Why it's wrong here
If agent were missing, the association would not run at all.
✓
The script does not check the exit code of the installation command and always returns 0.
Why this is correct
If the script doesn't propagate failure exit codes, State Manager sees success.
Clue confirmation

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.
