- A
Hot, because it is optimized for frequent access and immediate retrieval.
Why wrong: Hot is online and immediately readable, but it is typically more expensive than necessary for infrequently accessed data.
- B
Cool, because it is online and suited to infrequent access while remaining immediately readable.
Why wrong: Cool is an online tier and can work, but the question asks for the best fit when data is accessed rarely and immediate availability is required. There is a more cost-optimized online option.
- C
Archive, because it is the lowest-cost option and can still be read instantly.
Why wrong: Archive is the lowest-cost storage tier, but it is offline. It cannot satisfy the requirement for immediate reading.
- D
Cold, because it is designed for infrequently accessed data and remains online for immediate reads.
Cold is the best fit for data that is rarely read but must still be available immediately when needed. It keeps the blob online, unlike Archive, so there is no waiting for rehydration. This makes it suitable for compliance documents or records that are accessed occasionally but must open quickly during reviews.
AZ-104 Implement and Manage Storage Practice Question
This AZ-104 practice question tests your understanding of implement and manage storage. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 compliance team keeps signed contract scans in Azure Blob Storage. The files are usually read only a few times per year, but when a reviewer needs one, it must be available immediately without waiting for rehydration. Which access tier should the administrator use?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"immediately / without restart"Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
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
Cold, because it is designed for infrequently accessed data and remains online for immediate reads.
The Cold access tier is designed for data that is infrequently accessed but must remain online and immediately readable without any rehydration delay. Since the compliance team needs instant access to contract scans when requested, Cold tier provides low-cost storage while keeping data online, unlike Archive which requires rehydration.
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.
- ✗
Hot, because it is optimized for frequent access and immediate retrieval.
Why it's wrong here
Hot is online and immediately readable, but it is typically more expensive than necessary for infrequently accessed data.
- ✗
Cool, because it is online and suited to infrequent access while remaining immediately readable.
Why it's wrong here
Cool is an online tier and can work, but the question asks for the best fit when data is accessed rarely and immediate availability is required. There is a more cost-optimized online option.
- ✗
Archive, because it is the lowest-cost option and can still be read instantly.
Why it's wrong here
Archive is the lowest-cost storage tier, but it is offline. It cannot satisfy the requirement for immediate reading.
- ✓
Cold, because it is designed for infrequently accessed data and remains online for immediate reads.
Why this is correct
Cold is the best fit for data that is rarely read but must still be available immediately when needed. It keeps the blob online, unlike Archive, so there is no waiting for rehydration. This makes it suitable for compliance documents or records that are accessed occasionally but must open quickly during reviews.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'lowest cost' (Archive) with 'immediate availability,' forgetting that Archive requires a rehydration process that can take hours, making it unsuitable for on-demand access.
Detailed technical explanation
How to think about this question
Azure Blob Storage access tiers (Hot, Cool, Cold, Archive) have different storage costs and access costs; Cold tier offers lower storage cost than Cool with similar online availability. The Cold tier was introduced to fill the gap between Cool and Archive, providing immediate read access for data accessed only a few times per year without the rehydration latency of Archive. Under the hood, Cold tier data resides on the same online storage infrastructure as Hot and Cool, but with higher access charges to offset the lower storage price.
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.
