- A
Change the blob access tier from Archive to Hot or Cool.
Archived blobs are offline, so the blob must first be rehydrated into an online tier such as Hot or Cool before it can be read.
- B
Wait until the rehydration operation finishes.
The blob is not immediately readable after the tier change. Access is available only after the rehydration process completes.
- C
Download the blob directly from Archive without any tier change.
Why wrong: Archive tier data is offline and cannot be read directly. The blob must be rehydrated first before a normal download works.
- D
Disable the lifecycle management policy for the storage account.
Why wrong: Stopping the policy does not make an archived blob readable. The immediate issue is the blob's tier, not the policy assignment itself.
- E
Create a new container and copy the archived blob into it.
Why wrong: Copying the blob does not bypass the Archive tier state. The original blob still needs rehydration before it can be accessed normally.
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 support engineer finds a blob that was moved to the Archive tier by a lifecycle rule and must download it today. Which two actions are required before the blob can be read? 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
Change the blob access tier from Archive to Hot or Cool.
Option A is correct because a blob in the Archive tier is offline and cannot be read directly. You must change its access tier to Hot or Cool (a process called rehydration) to make it available for download. This tier change initiates an asynchronous operation that moves the blob from the archived state to an online tier.
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 often think they can directly download or copy an archived blob without rehydration, overlooking that Archive tier blobs are offline and require a tier change operation to become readable.
Detailed technical explanation
How to think about this question
Rehydration from the Archive tier involves a background operation where the blob data is moved to a Hot or Cool tier, which can take up to 15 hours depending on the priority set (Standard or High). During rehydration, the blob's status changes to 'rehydrate-pending-to-hot' or 'rehydrate-pending-to-cool', and read operations are blocked until completion. This process uses Azure's internal blob storage infrastructure to decompress and relocate data from long-term archival storage to active storage nodes.
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.
