The answer is that you must create the key as a customer managed key (CMK) and then enable automatic key rotation on that key. This is correct because AWS KMS automatic key rotation, which rotates the cryptographic material annually, is a feature exclusive to customer managed keys; AWS managed keys do not support this option, and imported key material cannot be rotated automatically. On the AWS Certified Security Specialty SCS-C02 exam, this concept tests your understanding of the key management lifecycle and the distinction between key types, often appearing as a trap where candidates mistakenly think IAM permissions or CloudTrail logging are prerequisites for rotation. A common memory tip is to remember that only keys you own and manage—customer managed keys—can be set on autopilot for rotation, while AWS managed keys are on a fixed schedule you cannot control. Just think: "Customer managed, rotation enabled; AWS managed, rotation disabled."
SCS-C02 Data Protection Practice Question
This SCS-C02 practice question tests your understanding of data protection. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 is using AWS Key Management Service (KMS) with a customer managed key. The security team needs to ensure that the key can be rotated automatically every year. Which TWO steps are required?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable automatic key rotation in the KMS console or API.
The correct answers are A and C. Option A: Automatic key rotation can be enabled on the KMS key. Option C: The key must be a customer managed key because automatic rotation is not available for AWS managed keys. Option B: IAM permissions are not required for rotation. Option D: Imported key material cannot be automatically rotated. Option E: CloudTrail logging is not a prerequisite for rotation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Ensure the key material is generated by AWS KMS, not imported.
Why it's wrong here
Imported key material cannot be automatically rotated.
✗
Grant the KMS service principal permission to rotate the key.
Why it's wrong here
Automatic rotation is handled by AWS; no additional permissions needed.
✓
Create the key as a customer managed key (CMK).
Why this is correct
Automatic rotation is available only for CMKs.

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.
