- A
Change the lifecycle rule so the blob will automatically move back to Hot on the next run.
Why wrong: Lifecycle rules do not instantly restore archived blobs, and waiting for the next run does not satisfy the urgent retrieval requirement.
- B
Set the blob directly to the Hot tier and download it immediately.
Why wrong: Archived blobs are offline and cannot be accessed immediately just by changing the tier; rehydration must complete first.
- C
Start a high-priority rehydration of the blob to the Hot tier, then wait for completion before downloading.
Archive tier data is offline and must be rehydrated before it can be read. High-priority rehydration is the fastest recovery option when the blob is needed urgently, and Hot is appropriate when the user wants normal online access after the operation completes.
- D
Copy the archived blob to another container by using the portal copy command.
Why wrong: A copy operation still requires the archived data to be available first, so it does not bypass the rehydration requirement.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Quarterly invoices were moved to the Archive tier by a lifecycle rule. An auditor now needs one specific blob available for download within the next hour. What should the administrator do?
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 a high-priority rehydration of the blob to the Hot tier, then wait for completion before downloading.
Option C is correct because blobs in the Archive tier are offline and must be rehydrated to an online tier (Hot or Cool) before they can be accessed. A high-priority rehydration completes within one hour, meeting the auditor's deadline. Changing a lifecycle rule (A) or directly setting the tier (B) does not initiate the necessary rehydration process, and copying an archived blob (D) fails because the blob is offline.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the lifecycle rule so the blob will automatically move back to Hot on the next run.
Why it's wrong here
Lifecycle rules do not instantly restore archived blobs, and waiting for the next run does not satisfy the urgent retrieval requirement.
- ✗
Set the blob directly to the Hot tier and download it immediately.
Why it's wrong here
Archived blobs are offline and cannot be accessed immediately just by changing the tier; rehydration must complete first.
- ✓
Start a high-priority rehydration of the blob to the Hot tier, then wait for completion before downloading.
Why this is correct
Archive tier data is offline and must be rehydrated before it can be read. High-priority rehydration is the fastest recovery option when the blob is needed urgently, and Hot is appropriate when the user wants normal online access after the operation completes.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates assume you can directly change the tier of an archived blob (like from Cool to Hot) without realizing that Archive-tier blobs are offline and require a separate rehydration step before any tier change or access is possible.
Detailed technical explanation
How to think about this question
Azure Blob Storage rehydration works by moving the blob from the offline Archive tier to an online tier (Hot or Cool) via a Set Blob Tier or Copy Blob operation. A high-priority rehydration sets the x-ms-rehydrate-priority header to 'High', which typically completes within one hour, whereas standard priority can take up to 15 hours. During rehydration, the blob's tier changes to 'RehydratePendingToHot' or 'RehydratePendingToCool', and the blob remains inaccessible until the process finishes.
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.
