The correct answer is to automate containment actions using AWS Lambda and AWS Systems Manager, document procedures and contacts, and test the plan via simulations. These three steps form the core of an effective incident response plan for AWS because they directly address the need for speed, clarity, and validation. Automating containment with serverless functions and Systems Manager drastically reduces the mean time to respond (MTTR), while thorough documentation ensures no critical step or stakeholder is missed during a crisis, and regular simulations prove the plan works under pressure. On the AWS Certified Security Specialty SCS-C02 exam, this concept tests your understanding of the Incident Response domain, often appearing in scenario-based multiple-choice questions where distractors include using the root user for response actions or storing evidence in public S3 buckets—both of which violate security best practices. A useful memory tip is the acronym ADT: Automate, Document, Test, which covers the three pillars of a robust incident response plan.
SCS-C02 Threat Detection and Incident Response Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident 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.
Which THREE steps should a security engineer take to ensure that an incident response plan for an AWS environment is effective? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Regularly test the incident response plan through tabletop exercises and simulations.
Options A, B, and C are correct. Testing the plan via simulations (A) validates its effectiveness. Automating containment actions (B) reduces response time. Documenting procedures and contacts (C) ensures clarity. Option D is wrong because using the root user for incident response is a security risk. Option E is wrong because storing evidence in public S3 buckets is insecure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Use the AWS account root user for incident response actions to ensure full permissions.
Why it's wrong here
Root user should be avoided due to security risks.
✗
Store all evidence in an S3 bucket with public read access for easy sharing.
Why it's wrong here
Public access is insecure.
✓
Automate containment actions using AWS Lambda and AWS Systems Manager.
Why this is correct
Automation reduces response time.

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.
What to study next
