Correct answer & explanation
✓
Review AWS CloudTrail logs for any unauthorized API calls
Options A, C, and D are correct. Rotating the access key invalidates the old key. Revoking temporary credentials ensures no active sessions. Reviewing CloudTrail logs helps assess the impact. Option B is incorrect because deleting the user is too drastic and not necessary. Option E is incorrect because changing the password does not affect access keys.
Key principle: 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.
