- A
Store logs in Cloud Logging with default retention.
Why wrong: Wrong: Default retention in Cloud Logging only controls how long logs are stored, not their integrity. Logs can still be modified or deleted within the retention period.
- B
Enable Access Transparency logs for the project.
Why wrong: Wrong: Access Transparency logs show when Google employees access your data, but they do not prevent tampering of your own Cloud Audit Logs.
- C
Use Cloud Key Management Service to sign audit logs.
Correct: Cloud KMS can be used to cryptographically sign audit logs. This creates a signature that can be verified later to detect any modifications, ensuring log integrity.
- D
Set up multiple log sinks to different destinations.
Why wrong: Wrong: Multiple log sinks only replicate logs to different destinations; they do not provide any mechanism to prevent tampering of the original logs.
PCSE Cloud KMS Practice Question
This PCSE practice question tests your understanding of cloud kms. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. A key principle to apply: cloud KMS. 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.

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Use Cloud Key Management Service to sign audit logs.
Option C is correct because Cloud Key Management Service (Cloud KMS) can be used to sign audit logs, providing a cryptographic integrity check that ensures logs have not been tampered with. Signed logs allow verification of their authenticity and detect any unauthorized changes. Option A is wrong because default retention in Cloud Logging does not prevent tampering; it only sets how long logs are kept. Option B is wrong because Access Transparency logs record actions by Google personnel, but they do not directly prevent tampering of Cloud Audit Logs. Option D is wrong because sending logs to multiple destinations increases redundancy but does not protect against tampering.

Key takeaway
Cloud KMS
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.
