DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 Systems Manager to manage a fleet of EC2 instances. During an incident, a DevOps engineer needs to execute a script on a specific instance to collect diagnostic data. The engineer does not have SSH key access. Which approach should the engineer use to execute the script?
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 Run Command to execute the script.
Option C is correct because AWS Systems Manager Run Command can execute scripts on EC2 instances without requiring SSH or RDP access, using the SSM Agent. Option A is wrong because AWS OpsWorks requires an agent and is typically used for Chef/Puppet. Option B is wrong because EC2 Instance Connect requires SSH key and port 22. Option D is wrong because SSM Session Manager is for interactive sessions, not script execution triggered as a command.
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.
✓
Use AWS Systems Manager Run Command to execute the script.
Why this is correct

Related concept
Read the scenario before looking for a memorised answer.
✗
Use AWS OpsWorks to run the script as a Chef recipe.
Why it's wrong here
AWS OpsWorks is not designed for ad-hoc command execution without SSH.
✗
Use EC2 Instance Connect to SSH into the instance and run the script.
Why it's wrong here
EC2 Instance Connect requires port 22 open and SSH key provisioning.
✗
Use AWS Systems Manager Session Manager to open a shell and run the script.
Why it's wrong here
Session Manager provides interactive access, not a one-shot command execution.

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.
