SCS-C02 Threat Detection and Incident Response Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident response. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 security engineer is investigating a potential security incident involving an Amazon RDS database. The engineer needs to identify which of the following actions should be taken during the forensic analysis phase? (Select TWO.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Take a manual snapshot of the RDS instance.
Option D is correct because taking a manual snapshot preserves a point-in-time, immutable copy of the RDS instance for offline forensic analysis without altering the live database. This ensures that evidence is captured before any changes occur during the investigation, and the snapshot can be restored to a separate instance for safe examination.
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.
✗
Enable automatic backups if not already enabled.
Why it's wrong here
Automatic backups are for recovery, not forensics.
✗
Disable deletion protection to allow cleanup.
Why it's wrong here
This could be part of remediation but not forensic analysis.
✗
Modify the security group to restrict database access.
Why it's wrong here
This is a containment action, not forensic analysis.
✓
Take a manual snapshot of the RDS instance.
Why this is correct
A manual snapshot preserves the database state for analysis.

Read the scenario before looking for a memorised answer.
✓
Review AWS CloudTrail logs for API calls related to the RDS instance.
Why this is correct
CloudTrail logs provide an audit trail of actions taken on the instance.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing containment actions (like modifying security groups) with forensic preservation actions, leading candidates to select Option C instead of recognizing that the first step in forensic analysis is to capture immutable evidence via a snapshot and review CloudTrail logs.
Detailed technical explanation
How to think about this question
RDS manual snapshots are stored in Amazon S3 and are independent of the source instance lifecycle, meaning they persist even if the original DB instance is terminated. CloudTrail logs capture data-plane and control-plane API calls (e.g., ModifyDBInstance, CreateDBSnapshot) with IAM user ARN, source IP, and request parameters, enabling reconstruction of the attack timeline. In a real-world scenario, an attacker might have used stolen credentials to modify security groups or delete logs, so a snapshot provides a forensically sound copy of the database state at the time of the incident.
KKey Concepts to Remember

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.
