- A
Download the blobs directly from Archive with a normal read operation.
Why wrong: Archive blobs are offline, so a normal read request cannot retrieve the data immediately from the archive tier.
- B
Initiate a rehydration to the Cool tier before the review window.
Rehydrating to Cool makes the data online again at a lower cost than Hot, which fits infrequent access during a short review.
- C
Set the blobs to the Hot tier permanently as soon as the review starts.
Why wrong: Hot works technically after rehydration, but permanently leaving compliance data in Hot increases storage cost unnecessarily.
- D
Move the blobs back to Archive after the review window ends.
Returning the blobs to Archive after the review restores the lowest-cost tier once auditors no longer need active access.
- E
Change the storage account redundancy to RA-GRS so the files can be read.
Why wrong: Redundancy affects durability and regional availability, not whether archived blobs are online or readable immediately.
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.
A legal team stores scanned contracts in Blob Archive. Auditors will need to open several files next week for about five days and then the documents should return to the lowest practical storage cost. Which two actions should the administrator plan? Select two.
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
Initiate a rehydration to the Cool tier before the review window.
Option B is correct because blobs in the Archive tier are offline and cannot be read directly; they must first be rehydrated to a hot or cool tier. Rehydrating to the Cool tier is appropriate for a five-day access window and avoids the higher cost of the Hot tier. After the review, moving the blobs back to Archive (Option D) ensures the lowest practical storage cost for long-term retention.
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 assume Archive blobs can be read directly (like a normal download) or that changing redundancy (RA-GRS) somehow bypasses the offline nature of Archive, when in fact rehydration is mandatory and redundancy settings only affect replication, not tier accessibility.
Detailed technical explanation
How to think about this question
Rehydration from Archive to Cool or Hot tier involves changing the blob's access tier, which triggers an internal copy operation that can take up to 15 hours (for Archive to Cool) depending on blob size and priority. The Cool tier is optimal for short-term access because its storage cost is lower than Hot, while its higher read costs are negligible for a five-day window. After rehydration, the blob remains in the Cool tier until explicitly moved back to Archive, which is a separate tier-change operation that incurs a write cost but minimizes ongoing storage expense.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
