A company stores sensitive financial documents in Azure Blob Storage. The security team needs to maintain an immutable log of all changes to the blob content, including the previous versions and the identity of the user who made the changes, for forensic analysis. Which Azure Storage feature should they enable on the storage account to meet this requirement?
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.
A
Distractor review
Azure Blob Storage soft delete.
Soft delete protects against accidental deletion by retaining deleted data for a period, but it does not provide a changelog for updates or show who made the changes.
B
Distractor review
Azure Blob Storage versioning.
Versioning automatically saves the previous versions of a blob, but it does not provide a chronological log of changes with user identity. It is useful for recovery but not for a detailed audit trail of all operations.
C
Best answer
Blob Storage change feed.
The change feed records all modifications to blobs in an immutable event log. It can be used with Azure Diagnostics logs to correlate user identity (from storage analytics) to understand who performed the action.
D
Distractor review
Azure Storage analytics logs.
Storage analytics logs capture detailed information about requests to the storage service, including user identity. However, logs are not immutable and can be overwritten; they are typically used for monitoring, not as a guaranteed audit trail. The change feed provides an immutable ordered log.
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: Blob Storage change feed. — Blob Storage change feed provides an ordered, guaranteed, and immutable log of all changes (create, update, delete) to blobs. It captures the change events in a format that can be processed by Azure Event Grid or other consumers. Combined with storage analytics logs, it can show who made the change (if authenticated access is used). The change feed itself is immutable and ordered per blob, making it suitable for audit trails.
