Full question →easymultiple choiceObjective-mapped
A financial company must store customer transaction records in Azure Blob Storage. Regulatory requirements mandate that the records must not be modified or deleted for 7 years. Even administrators must be unable to alter or remove the blobs during this period. Which Azure Blob Storage feature should they enable?
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
Best answer
Immutable storage with time-based retention policy
Correct. A time-based retention policy enforces WORM for a fixed period, satisfying the 7-year regulatory requirement.
B
Distractor review
Legal hold
Legal hold is indefinite and must be manually removed. It does not provide a fixed time-based retention.
C
Distractor review
Soft delete
Soft delete helps recover deleted blobs but does not prevent initial deletion or modification.
D
Distractor review
Versioning
Versioning preserves previous versions but does not prevent the current version from being updated or deleted.
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-305 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 with time-based retention policy — Azure Blob Storage supports immutable storage with time-based retention policies that enforce a write-once, read-many (WORM) state for a specified duration. This prevents any modification or deletion, meeting compliance requirements. Legal hold is for indefinite holds, soft delete recovers deleted blobs, and versioning tracks changes but does not prevent deletion.
