SCS-C02 Threat Detection and Incident Response Practice Question
This SCS-C02 practice question tests your understanding of threat detection and incident 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.
Network Topology
A security engineer runs the above AWS CLI command to search for CreateKey events in CloudTrail. The command returns no events, but the security engineer knows that a KMS key was created in us-east-1 on January 1, 2023. What is the most likely reason for the empty result?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Network Topology
A
The event name is incorrect; the correct event is 'CreateKey' but it is case-sensitive
Why wrong: The event name is case-sensitive but 'CreateKey' is correct.
B
The CloudTrail trail is not multi-region and is configured in a different region
If the trail is single-region and in another region, us-east-1 events are not captured.
C
The user does not have permission to view KMS events in CloudTrail
Why wrong: The error would be an access denied, not empty results.
D
The time range specified is outside the retention period of CloudTrail
Why wrong: CloudTrail retains logs for 90 days by default; the date is within that.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The CloudTrail trail is not multi-region and is configured in a different region
Option B is correct because CloudTrail trails are region-specific by default. If the trail is configured only in a region other than us-east-1, it will not capture events from us-east-1, even if the security engineer is running the command from us-east-1. A multi-region trail must be explicitly enabled to log events from all AWS regions, including us-east-1.
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 the AWS CLI command's region parameter (--region us-east-1) overrides the trail's configuration, but CloudTrail trails are independent of the CLI region and only log events from the regions they are configured to cover.
Detailed technical explanation
How to think about this question
CloudTrail trails can be single-region or multi-region. A single-region trail only delivers log files for events that occur in the region where the trail is created. To capture events from all regions, you must enable the 'IsMultiRegionTrail' attribute when creating the trail. Additionally, KMS CreateKey events are always logged as management events, so they should appear in the trail if the trail covers the region and has management events enabled.

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.
