- A
Copy the blob to a new container and leave it in the Archive tier until the users need it.
Why wrong: Copying the blob does not avoid archive behavior. An archived blob still requires rehydration before it can be read online.
- B
Start rehydration from Archive and choose High priority.
Archive blobs cannot be read immediately. To make the blob available within the shortest practical time, the administrator should rehydrate it and select High priority so Azure processes the request faster than the standard option.
- C
Change the access tier from Archive directly to Cool and then download the blob immediately.
Why wrong: The blob cannot be downloaded immediately after a tier change from Archive. Rehydration still has to complete before the data becomes readable again.
- D
Enable soft delete on the container and restore the blob from deleted items.
Why wrong: Soft delete helps recover deleted blobs, not blobs that are intentionally in the Archive tier. This scenario is about rehydrating an archived object, not restoring a deletion.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A legal department archived a 120-GB blob three weeks ago. They now need the file available for review later today, and waiting more than a day would delay a court filing. What should the administrator do to make the blob readable as quickly as possible?
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
Start rehydration from Archive and choose High priority.
Option B is correct because rehydrating a blob from the Archive tier with High priority typically makes the blob readable within 1 hour, meeting the urgent same-day requirement. The Archive tier is offline, so the blob must be rehydrated (changed to an online tier like Hot or Cool) before it can be accessed. High-priority rehydration is designed for time-sensitive scenarios like this court filing deadline.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may think changing the access tier directly (Option C) is instantaneous, but Azure requires a rehydration process that can take up to 15 hours for standard priority, making High-priority rehydration (Option B) the only viable choice for same-day access.

Detailed technical explanation
How to think about this question
Azure Blob Storage rehydration from the Archive tier involves moving the blob to an online tier (Hot, Cool, or Cold). Standard-priority rehydration can take up to 15 hours, while High-priority rehydration is typically completed within 1 hour for objects under 10 GB, though larger blobs (like this 120-GB one) may take slightly longer but still far less than a day. The rehydration process is asynchronous; you must poll the blob's 'Rehydration Status' property until it changes from 'rehydrate-pending-to-[tier]' to the target tier before the blob is readable.
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.
TExam Day Tips
- 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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
