- A
Set up an AWS Config rule that triggers a Lambda function to remove the SSH rule.
Why wrong: This is possible but Config's built-in remediation is simpler and recommended.
- B
Use Amazon CloudWatch Events to detect the change and invoke a Lambda function.
Why wrong: This is reactive to changes, not proactive remediation of existing non-compliance.
- C
Use AWS Service Catalog to enforce security group templates.
Why wrong: Service Catalog is for approved product creation, not remediation.
- D
Create an AWS Config rule with an automatic remediation action using AWS Systems Manager Automation.
Config remediation can run an SSM Automation document to remove the rule.

DOP-C02 Incident and Event Response Practice Question
This DOP-C02 practice question tests your understanding of incident and event response. 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 uses AWS Config to track resource changes. They want to automatically remediate non-compliant security group rules that allow public SSH access. What is the MOST effective approach?
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
✓
Create an AWS Config rule with an automatic remediation action using AWS Systems Manager Automation.
Option D is correct because AWS Config can directly associate an AWS Systems Manager Automation document as a remediation action for a non-compliant rule. This approach provides a fully managed, idempotent, and auditable remediation workflow without requiring custom Lambda code or external event orchestration. The automation document can be configured to automatically remove the SSH ingress rule (port 22) from the security group when the Config rule detects non-compliance.
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
The trap here is that candidates often assume a custom Lambda function (Option A) is the most flexible or effective approach, but AWS Config's native remediation with Systems Manager Automation is the recommended, fully managed, and less error-prone solution for automatic compliance enforcement.
Detailed technical explanation
How to think about this question
AWS Config remediation uses Systems Manager Automation documents (e.g., AWS-DisablePublicAccessForSecurityGroup) that can be parameterized to target specific resources. The remediation action is invoked automatically when the Config rule evaluation result is NON_COMPLIANT, and it supports retry logic, rate limiting, and error handling via AWS Config's built-in remediation lifecycle. Under the hood, the automation document executes an AWS CLI command (e.g., revoke-security-group-ingress) against the specific security group ID and rule, ensuring the change is logged in CloudTrail for full auditability.
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.
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 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.
