Cloud Audit Log Types and Defaults

Which TWO of the following are true regarding Cloud Audit Logs?

Quick Answer

The correct answer is that System Event audit logs record non-human administrative actions and are enabled by default, alongside Admin Activity logs which are always enabled and cannot be disabled. This is because Cloud Audit Logs are divided into three main types: Admin Activity logs track human-initiated administrative actions, System Event logs capture Google Cloud system-generated actions like automatic updates or resource creation, and Data Access logs track API calls that read or modify user data. On the Google Professional Cloud Security Engineer exam, this distinction tests your understanding of default audit log configurations and retention policies, with a common trap being that Data Access logs are disabled by default and must be explicitly enabled, while all audit logs are retained for 400 days. A useful memory tip is to remember that "Admin and System are always on, Data Access must be drawn."

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

Admin Activity audit logs are enabled by default and cannot be disabled.

Options B and E are correct. Admin Activity audit logs are enabled by default and cannot be disabled. System Event audit logs are also enabled by default and record non-human administrative actions. Option A is incorrect because Data Access audit logs are disabled by default and must be explicitly enabled. Option C is incorrect because Cloud Audit Logs have a default retention period of 400 days, not indefinite. Option D is incorrect because Cloud Audit Logs provide logs, not monitoring metrics for log volume.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • Data Access audit logs are enabled by default for all services.

    Why it's wrong here

    Disabled by default; must be explicitly enabled.

    Default retention is 400 days.

  • Cloud Audit Logs include monitoring metrics for log volume.

    Why it's wrong here

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. A security operations team is using Cloud Audit Logs to investigate a suspicious data export from a Cloud Storage bucket. They need to see which user accessed a specific object and when. Which log type should they examine?

medium
  • A.Data Access logs
  • B.Policy Denied logs
  • C.System Event logs
  • D.Admin Activity logs

Why A: Data Access logs capture all operations that read, write, or delete data in Cloud Storage objects, including who accessed a specific object and when. Admin Activity logs record only configuration changes, not data access events.
