- A
Hot, because it is optimized for frequent reads and online access to active data.
Hot is the best fit for data that is accessed often and needs immediate online availability.
- B
Cool, because it is designed for infrequent access while still keeping blobs online.
Cool is appropriate for older files that are still online but read less often.
- C
Archive, because it is best for data that must be opened immediately by users.
Why wrong: Archive is offline storage and requires rehydration before the blob can be read again.
- D
Premium block blob, because it is the standard tier for long-term retention and low-cost storage.
Why wrong: Premium block blob is a performance-oriented option, not the usual choice for this access pattern.
- E
Cold, because it is intended for data that can stay offline until someone requests it.
Why wrong: Cold is still online storage, but this option suggests offline behavior, which does not match the requirement.
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 records team stores blobs that are read often during the first month and then rarely accessed later, but the files must stay online the whole time. Which two access tiers should they use for the active and inactive data sets? 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
Hot, because it is optimized for frequent reads and online access to active data.
Option A is correct because the Hot access tier is optimized for frequent reads and provides low-latency online access, making it ideal for the active data set that is read often during the first month. Option B is correct because the Cool access tier is designed for infrequently accessed data that must remain online, with lower storage costs but higher access costs, perfectly matching the rarely accessed but always online requirement.
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 confuse the Cool tier with the Archive tier, assuming 'infrequent access' means offline, or they mistakenly think the Cold tier (which is offline) satisfies the 'online' requirement, but the question explicitly states files must stay online the whole time.
Detailed technical explanation
How to think about this question
Azure Blob Storage access tiers (Hot, Cool, Cold, Archive) have different storage and access cost profiles. The Hot tier charges higher storage costs but lower access costs, while the Cool tier offers lower storage costs but higher access costs (per GB read). The transition between tiers can be automated using lifecycle management policies (e.g., move blobs from Hot to Cool after 30 days). The Archive tier requires rehydration (up to 15 hours) before data can be read, making it unsuitable for online-only requirements.
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.
