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 media archive contains video files that are accessed only a few times per year, but they must remain online and readable immediately whenever an investigator requests them. Which blob access tier should the administrator choose to minimize storage cost?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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
The Cold tier is the correct choice because it provides online, immediately readable storage for data accessed only a few times per year, while offering lower storage costs than the Cool tier. Unlike the Archive tier, Cold tier data does not require a rehydration delay, ensuring instant access for investigators.
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
Why it's wrong here
Hot is designed for frequent access and usually costs more to store than colder tiers.
When this WOULD be correct
A question where data is accessed frequently (e.g., multiple times per day or week) and requires low latency, such as a live video streaming service or a real-time analytics platform. The Hot tier minimizes access costs and provides the best performance for frequent reads.
- ✗
Cool
Why it's wrong here
Cool is suitable for infrequent access, but Cold is generally better for even less frequent reads.
When this WOULD be correct
An administrator needs to store data that is accessed about once a month, with immediate retrieval required. The Cool tier offers lower storage cost than Hot while still providing low-latency access for monthly access patterns.
- ✓
Cold
Why this is correct
Cold is intended for very infrequently accessed data that still needs to stay online and readable immediately.
Clue confirmation
The clue words "minimum / minimize", "immediately / without restart" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Archive
Why it's wrong here
Archive is offline and would require rehydration before the investigators could read the files.
When this WOULD be correct
A question where data is rarely accessed (e.g., once per year) and immediate read access is not required, such as long-term backup or compliance archives where retrieval latency of up to 15 hours is acceptable.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓ColdCorrect answer▾
Why this is correct
Cold is intended for very infrequently accessed data that still needs to stay online and readable immediately.
✗HotWrong answer — click to see why▾
Why this is wrong here
The Hot tier is designed for frequently accessed data with high availability and low access latency, but it has the highest storage cost. For data accessed only a few times per year, the Hot tier would be unnecessarily expensive.
★ When this WOULD be the correct answer
A question where data is accessed frequently (e.g., multiple times per day or week) and requires low latency, such as a live video streaming service or a real-time analytics platform. The Hot tier minimizes access costs and provides the best performance for frequent reads.
Why candidates choose this
Candidates may think 'Hot' is always the best for immediate readability, overlooking that storage cost is the primary concern and that Cold tier also offers immediate readability at lower cost.
✗CoolWrong answer — click to see why▾
Why this is wrong here
The Cool tier is designed for data accessed infrequently (30+ days) but still requires lower latency than Cold. However, the question specifies access only a few times per year, which aligns better with Cold tier's longer access interval and lower cost, making Cool more expensive than necessary.
★ When this WOULD be the correct answer
An administrator needs to store data that is accessed about once a month, with immediate retrieval required. The Cool tier offers lower storage cost than Hot while still providing low-latency access for monthly access patterns.
Why candidates choose this
Candidates may confuse 'infrequent access' with 'few times per year' and choose Cool as a middle ground, not realizing Cold tier is specifically optimized for yearly access patterns with even lower cost.
✗ArchiveWrong answer — click to see why▾
Why this is wrong here
The Archive tier has the lowest storage cost but requires hours to rehydrate data before reading, violating the requirement that files remain 'readable immediately' upon request.
★ When this WOULD be the correct answer
A question where data is rarely accessed (e.g., once per year) and immediate read access is not required, such as long-term backup or compliance archives where retrieval latency of up to 15 hours is acceptable.
Why candidates choose this
Candidates see 'accessed only a few times per year' and assume the cheapest tier (Archive) is best, overlooking the 'readable immediately' constraint that makes Cold the correct choice.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the Archive tier's 'immediate online access' with its actual requirement for rehydration, leading them to choose Archive for cost savings without considering the access latency constraint.
Detailed technical explanation
How to think about this question
Azure Blob Storage access tiers (Hot, Cool, Cold, Archive) have different storage and access costs, with Cold tier offering a balance of low storage cost and no rehydration latency. The Cold tier has a 30-day minimum storage duration and a higher early deletion fee than Cool, but for data accessed only a few times per year, the storage savings outweigh these costs. Under the hood, Cold tier data is stored on lower-cost media but remains directly accessible via standard blob read operations without any explicit rehydration step.
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.
Quick reference
Azure Blob Storage Tier Comparison
| Tier | Storage Cost | Retrieval Cost | Latency | Use Case |
|---|---|---|---|---|
| Hot | Highest | Lowest | Immediate | Active data, frequent reads |
| Cool | Lower | Higher | Immediate | Data accessed < once / month |
| Cold | Lower still | Higher | Immediate | Data accessed < once / quarter |
| Archive | Lowest | Highest + rehydration delay | Hours | Long-term compliance retention |
