A batch job fails with a blob read error after the administrator moved a 200-GB blob to the archive tier. The file must be available again within a few hours, and the administrator wants the least disruptive recovery. What should be done?
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
Delete the archived blob and upload a new copy from backup.
Deleting and reuploading is more disruptive than necessary and depends on having another copy available immediately.
Best answer
Change the blob tier to Hot or Cool and wait for the rehydration process to finish.
Archive blobs are offline and cannot be read directly until they are rehydrated. The administrator should change the tier from Archive to Hot or Cool, which starts rehydration and makes the blob readable again after the process completes. This is the least disruptive recovery path because it preserves the existing blob and uses the supported restore mechanism instead of recreating the data.
Distractor review
Enable soft delete on the storage account and retry the read operation.
Soft delete protects against deletion, but it does not bring an archived blob back online for reading.
Distractor review
Convert the storage account to premium performance.
Changing the account performance type does not automatically rehydrate archived data or resolve the read failure.
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-104 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Change the blob tier to Hot or Cool and wait for the rehydration process to finish. — When a blob is moved to the Archive tier, it becomes offline and cannot be read until rehydration finishes. The correct remediation is to initiate a tier change back to Hot or Cool, optionally with a rehydration priority if speed matters. That restores access without deleting the blob or relying on a secondary copy. For a file needed within hours, this is the proper operational recovery step. Why others are wrong: Deleting and reuploading is risky and unnecessary if the archived blob still exists. Soft delete only helps after deletion, not for archive access. Changing account performance does not alter the blob's archive state, so the read error would remain until rehydration is explicitly requested.
