A company enables Azure SQL Database auditing to log database events to a storage account. The security policy requires that the audit logs be protected from tampering and deletion after they are written. Which storage account feature should the company enable to ensure that audit log files cannot be modified or deleted by anyone for a specified retention period?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
Distractor review
Soft delete
Soft delete allows recovery of recently deleted blobs but does not prevent intentional deletion by users with write permissions. Audit logs could be tampered with before recovery.
Best answer
Immutable storage
Immutable storage (WORM) enforces a retention policy that blocks any modification or deletion of blobs for a specified duration, perfect for preserving audit logs.
Distractor review
Hierarchical namespace
Hierarchical namespace is used for Data Lake Storage to organize files into directories; it does not provide immutability or delete protection.
Distractor review
Firewall and virtual networks
Network access controls restrict who can connect to the storage account but do not prevent users who have access from modifying or deleting logs.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-500 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Immutable storage — Azure Storage Immutable Storage (also known as WORM policy) allows you to set a time-based retention policy that prevents blobs from being modified or deleted during the retention period. This is ideal for audit logs that must be kept intact. Soft delete enables recovery of deleted blobs but does not prevent deletion. Hierarchical namespace is for Azure Data Lake Storage Gen2 and provides a directory structure, not immutability. Firewall and virtual networks control network access but do not prevent authorized users from modifying or deleting logs.
