The answer is Data Access audit logs. These logs specifically capture API calls that read or modify user-provided data, such as SELECT queries in BigQuery, making them the exact fit for tracking read operations on a dataset. In contrast, Admin Activity logs record configuration changes like creating or deleting resources, while System Event logs cover actions initiated by Google systems, not user-driven reads. On the Google Associate Cloud Engineer exam, this distinction tests your understanding of Cloud Audit Log categories, often appearing in scenario-based questions where a compliance or security team needs granular data access tracking. A common trap is confusing Data Access logs with Admin Activity logs, but remember: if it touches user data, it’s Data Access; if it changes infrastructure, it’s Admin Activity. For a quick memory tip, think “Data Access = Data Reads and Writes; Admin Activity = Admin Actions.”
Google ACE Configuring access and security Practice Question
This ACE practice question tests your understanding of configuring access and security. 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.
A compliance team needs a log of every time a user or service account accessed data in a BigQuery dataset — specifically read operations. Which Cloud Audit Log type captures this?
Why wrong: System event logs capture GCP internal system actions (like live migration) — they don't record user-initiated data access.
B
Admin Activity audit logs
Why wrong: Admin Activity logs capture changes to resource configurations (creating/deleting datasets, modifying IAM policies) — not data reads.
C
Data Access audit logs
Data Access audit logs record API calls that read data — including BigQuery table reads and query executions. They must be explicitly enabled and can generate high log volume.
D
VPC flow logs
Why wrong: VPC flow logs capture network traffic metadata (source/destination IPs, ports) — they don't record which user accessed which BigQuery dataset.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Data Access audit logs
Data Access audit logs record API calls that read or modify user-provided data, including BigQuery read operations like SELECT queries. Since the requirement is specifically for read operations on user data, Data Access logs are the correct type. Admin Activity logs cover configuration changes, not data reads, and System Event logs cover Google-managed actions, not user-initiated reads.
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
Google Cloud often tests the distinction between Admin Activity logs (which capture resource configuration changes) and Data Access logs (which capture data reads/writes), leading candidates to mistakenly choose Admin Activity for any 'access' scenario.
Detailed technical explanation
How to think about this question
Data Access audit logs are enabled per service (e.g., BigQuery) and per log type (read, write, or admin) via the Audit Logs configuration in IAM. For BigQuery, read operations include jobs.query, jobs.getQueryResults, and tabledata.list, all of which are captured only if Data Access read logs are explicitly enabled. A common real-world scenario is auditing for compliance with GDPR or HIPAA, where every SELECT query on sensitive datasets must be logged.

→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.

Variation 1. A regulated company requires a log of all actions taken by Google support engineers when they access customer GCP environments during support cases. Which Cloud Audit Log type captures this?
hard
A.Admin Activity audit logs
B.Data Access audit logs with Google-initiated access filter
✓ C.Access Transparency logs
D.System event audit logs with personnel filter
Why C: Access Transparency logs are the correct choice because they specifically capture actions taken by Google support engineers when accessing customer data or configurations in GCP. These logs provide near real-time records of Google-initiated access, which is required for regulated companies to audit support personnel activities. Admin Activity logs only record administrative actions by customers, not Google personnel, while Data Access logs with Google-initiated access filter are not a valid log type in Cloud Audit Logs.
