DOP-C02 SDLC Automation Practice Question
This DOP-C02 practice question tests your understanding of sdlc automation. 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 enforce that all infrastructure changes go through a CI/CD pipeline. Which AWS service can be used to prevent direct changes to production resources?
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
✓
AWS Config
AWS Config can be used with AWS Config rules to evaluate resource configurations against desired policies. By creating a rule that requires all changes to go through a CI/CD pipeline (e.g., by checking that resources are tagged with a pipeline identifier or that changes are made via CloudFormation), AWS Config can detect noncompliant resources and trigger automated remediation (e.g., reverting changes or notifying administrators). This enforces the requirement that direct changes to production resources are prevented or flagged.
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 confuse AWS Config's detective and compliance evaluation capabilities with preventive controls, assuming it can block changes in real-time, whereas it only detects and can remediate after the fact, requiring complementary IAM or SCP policies for true prevention.
Detailed technical explanation
How to think about this question
AWS Config evaluates resources against managed or custom rules using AWS Lambda functions (for custom rules) and can automatically remediate noncompliant resources via AWS Systems Manager Automation documents. For example, a custom Config rule can check that an EC2 instance or an S3 bucket was created or modified only through a CloudFormation stack by inspecting the 'aws:cloudformation:stack-id' tag, and if missing, trigger a Lambda function to revert the change or notify an SNS topic. This provides a detective and reactive control, not a preventive one, but combined with IAM policies that deny direct API calls (e.g., using 'aws:ViaAWSService' condition keys), it can effectively enforce pipeline-only changes.
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.
