SCS-C02 Security Logging and Monitoring Practice Question
This SCS-C02 practice question tests your understanding of security logging and monitoring. 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 financial services company has a production AWS account with hundreds of EC2 instances running a mix of Linux and Windows workloads. The security team is responsible for detecting and responding to security incidents. They have enabled CloudTrail, VPC Flow Logs, and GuardDuty. Recently, GuardDuty generated a finding indicating that an EC2 instance is communicating with a known malicious IP address. The security engineer needs to investigate the incident. The engineer examines the GuardDuty finding and sees the affected resource is an EC2 instance ID. The engineer wants to identify which user or role launched the instance and what security groups were associated with it at launch time. Which approach should the engineer take to gather this information?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Search CloudTrail logs for the RunInstances event that created the instance, using the instance ID to filter.
Option A is correct because CloudTrail logs the RunInstances API call which includes the user identity, instance ID, and security group IDs. Option B is wrong because AWS Config records the configuration but not the user who launched it. Option C is wrong because EC2 console does not provide historical launch details. Option D is wrong because Systems Manager Inventory does not track launch user or initial security groups.
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.
✗
Log in to the EC2 console and view the instance details under the 'Security' tab.
Why it's wrong here
Console shows current state, not historical launch details.
✗
Use AWS Systems Manager Inventory to collect metadata about the instance.
Why it's wrong here
Inventory collects software and patch data, not launch user.
✓
Search CloudTrail logs for the RunInstances event that created the instance, using the instance ID to filter.
Why this is correct
CloudTrail captures the API call with user identity and parameters.

✗
Use AWS Config to view the configuration history of the EC2 instance and check the security group changes.
Why it's wrong here
Config shows configuration items but not the user who launched.

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.
