Auditing Azure Storage Access
Which TWO Azure services can be used to audit data access and changes in Azure Data Lake Storage Gen2? (Choose two.)
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
✓
Storage account diagnostic settings.
Storage account diagnostic settings (C) are correct because they can stream Data Lake Storage Gen2 resource logs—such as Read, Write, and Delete operations on blobs and ADLS Gen2 filesystems—to a Log Analytics workspace, storage account, or Event Hub, providing the raw audit trail of data access and changes. Azure Monitor and Microsoft Sentinel (D) are correct because Azure Monitor collects and queries those diagnostic logs (via Log Analytics/KQL) for auditing, while Microsoft Sentinel ingests the same storage/ADLS logs to detect, alert on, and investigate suspicious data-access activity. Microsoft Entra ID sign-in logs (A) only record authentication and token issuance events, not per-file data-plane operations, so they cannot audit data access or changes. Azure Backup reports (B) cover backup job status and protected-item health, not data-plane read/write/delete auditing. Azure Policy (E) evaluates and enforces resource configuration compliance (control plane), not individual data access or modification events.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Microsoft Entra ID sign-in logs.
Why it's wrong here
Microsoft Entra ID sign-in logs record authentication events against the directory, not data-plane operations such as reads, writes or ACL changes on Data Lake Storage Gen2 files. They are tempting because they do capture access attempts, but only at the identity layer; they would be the right choice for investigating suspicious sign-ins or conditional access failures.
- ✗
Azure Backup reports.
Why it's wrong here
Azure Backup reports track backup job status, protected items and recovery points, not data-plane reads, writes or permission changes in Data Lake Storage Gen2. They are tempting because they do surface storage-related activity, but they would be the right choice when auditing backup success, failures or retention compliance rather than file-level access auditing.
- ✓
Storage account diagnostic settings.
Why this is correct
Storage account diagnostic settings stream control-plane and data-plane events, including authenticated read, write and delete operations, to Log Analytics, storage or Event Hubs. This provides the audit trail of data access and changes required by the stem.
- ✓
Azure Monitor and Microsoft Sentinel.
Why this is correct
Azure Monitor collects and queries the diagnostic logs, while Microsoft Sentinel correlates them into detections and incidents. Together they deliver auditing of data access and changes across Data Lake Storage Gen2, satisfying the stem's requirement.
- ✗
Azure Policy.
Why it's wrong here
Azure Policy evaluates resource configurations against governance rules, so it cannot record who read or modified data in Data Lake Storage Gen2. It is tempting because it genuinely enforces compliance—denying non-compliant resource creation or auditing configuration drift across subscriptions—which suits governance scenarios, not data-plane access auditing.
