- A
Hot, because it prioritizes immediate access over storage cost.
Why wrong: Hot satisfies availability, but it is not the lowest-cost online choice for infrequently accessed evidence files.
- B
Cool, because it is an online tier for infrequent access.
Why wrong: Cool is online, but Cold is the better fit when access is even rarer and cost matters more.
- C
Cold, because it keeps data online and is intended for rarely accessed content.
Cold is the right tier because the files must remain immediately readable and cannot be placed into an offline state. The scenario says the data is accessed only a few times per year, so a lower-cost online tier is appropriate. Archive would introduce rehydration delay, which the business explicitly does not want. Cold preserves online availability while reducing storage cost compared with hotter tiers.
- D
Archive, because it has the lowest cost and can be opened instantly from the portal.
Why wrong: Archive is offline and requires rehydration before the file can be read again.
Quick Answer
The answer is the Cold tier, because it is the cheapest online blob storage tier with immediate access that keeps data online and requires no rehydration step. Unlike the Archive tier, which forces a costly and time-consuming retrieval process, Cold stores data on high-capacity drives that remain directly readable, making it ideal for rarely accessed evidence files that must be instantly available. On the AZ-104 exam, this scenario tests your ability to distinguish between online tiers (Hot, Cool, Cold) and offline tiers (Archive), with the common trap being to choose Archive for its lower storage cost—forgetting that Archive demands a rehydration delay. Remember the memory tip: “Cold is the coolest online tier for data that’s rarely told,” meaning it stays online and ready, unlike Archive which is offline and cold-stored.
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 legal department keeps evidence files in Azure Blob Storage. The files are accessed only a few times per year, but they must stay online and be immediately readable when requested. The team wants the lowest-cost online tier and does not want a rehydration step. Which tier should you choose?

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 keeps data online and is intended for rarely accessed content.
The Cold tier is the correct choice because it is an online tier designed for rarely accessed data that must remain immediately readable without a rehydration step. It offers lower storage costs than Hot or Cool while still providing instant access, meeting the requirement for the lowest-cost online tier.
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 prioritizes immediate access over storage cost.
Why it's wrong here
Hot satisfies availability, but it is not the lowest-cost online choice for infrequently accessed evidence files.
- ✗
Cool, because it is an online tier for infrequent access.
Why it's wrong here
Cool is online, but Cold is the better fit when access is even rarer and cost matters more.
- ✓
Cold, because it keeps data online and is intended for rarely accessed content.
Why this is correct
Cold is the right tier because the files must remain immediately readable and cannot be placed into an offline state. The scenario says the data is accessed only a few times per year, so a lower-cost online tier is appropriate. Archive would introduce rehydration delay, which the business explicitly does not want. Cold preserves online availability while reducing storage cost compared with hotter tiers.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.

Why it's wrong here
Archive is offline and requires rehydration before the file can be read again.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'lowest cost' with the Archive tier, forgetting that Archive is offline and requires a rehydration step, which violates the requirement for immediate readability without a rehydration step.
Detailed technical explanation
How to think about this question
Azure Blob Storage access tiers (Hot, Cool, Cold, Archive) are priced based on storage cost versus access cost; Cold tier offers lower storage cost than Cool but higher than Archive, with a 30-day minimum storage duration. The Cold tier is an online tier, meaning data is always accessible via HTTP/HTTPS without any latency penalty, unlike Archive which requires a rehydration operation to move data to an online tier. In real-world scenarios, legal or compliance teams often choose Cold for data that must be retained online for regulatory reasons but is rarely accessed, balancing cost and availability.
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.

Same concept, more angles
1 more ways this is tested on AZ-104
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You store long-term financial statements in Azure Blob Storage. The files are almost never accessed, but when they are needed they must be readable immediately without waiting for rehydration. You need to minimize cost. Which access tier should you use?
hard- A.Hot
- ✓ B.Cool
- C.Archive
- D.Premium
Why B: The Cool access tier is optimal for data that is infrequently accessed but must be available immediately when needed, offering lower storage costs than Hot while maintaining low-latency read access. Archive would require rehydration (taking hours) before reading, violating the requirement for immediate readability. Hot is more expensive for long-term storage of rarely accessed data, and Premium is designed for high-performance workloads, not cost-efficient archival.
