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.
Your company stores monthly reports in Azure Blob Storage. The reports are rarely accessed, but when needed they must be read within seconds rather than hours. You need to minimize storage cost while preserving near-immediate availability. Which access tier should you use?
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.
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
✓
Cool
Cool tier is correct because it offers low storage cost for infrequently accessed data while maintaining near-immediate (milliseconds) retrieval latency. The reports are rarely accessed but must be available within seconds, which Cool tier satisfies, whereas Archive would incur hours-long rehydration delays.
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 optimized for frequently accessed data and would cost more than necessary.
When this WOULD be correct
If the question specified that the reports are accessed frequently (e.g., multiple times per day) and low latency is critical, the Hot tier would be correct to balance performance and cost.
- ✓
Cool
Why this is correct
Cool minimizes cost for infrequently accessed data while keeping it available online.
Clue confirmation
The clue word "minimum / minimize" 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 requires rehydration and does not provide near-immediate access.
When this WOULD be correct
If the question stated that reports are accessed only a few times per year and retrieval can take up to 15 hours (e.g., for compliance archives where immediate access is not needed), Archive would be correct.
- ✗
Premium
Why it's wrong here
Premium is for high-performance workloads, not low-cost infrequently accessed reports.
When this WOULD be correct
A question requiring sub-millisecond latency for frequently accessed data, such as 'Your company runs a real-time analytics dashboard that requires consistent low-latency reads on blobs. Which tier minimizes latency?' would make Premium correct.
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.
✓CoolCorrect answer▾
Why this is correct
Cool minimizes cost for infrequently accessed data while keeping it available online.
✗HotWrong answer — click to see why▾
Why this is wrong here
The Hot tier is designed for frequently accessed data and has higher storage costs, which contradicts the requirement to minimize storage cost for rarely accessed reports.
★ When this WOULD be the correct answer
If the question specified that the reports are accessed frequently (e.g., multiple times per day) and low latency is critical, the Hot tier would be correct to balance performance and cost.
Why candidates choose this
Candidates may assume that 'near-immediate availability' requires the highest performance tier, overlooking that Cool tier also provides low-latency access at lower storage cost.
✗ArchiveWrong answer — click to see why▾
Why this is wrong here
Archive tier has the lowest storage cost but retrieval times can be hours (up to 15 hours for standard priority), which violates the requirement that reports must be read within seconds.
★ When this WOULD be the correct answer
If the question stated that reports are accessed only a few times per year and retrieval can take up to 15 hours (e.g., for compliance archives where immediate access is not needed), Archive would be correct.
Why candidates choose this
Candidates may focus solely on minimizing cost and overlook the 'within seconds' requirement, assuming Archive is always the cheapest option without considering retrieval latency.
✗PremiumWrong answer — click to see why▾
Why this is wrong here
Premium tier is designed for low-latency, high-transaction workloads (e.g., interactive apps), not for rarely accessed data. It costs significantly more than Cool and does not provide cost savings for infrequent access.
★ When this WOULD be the correct answer
A question requiring sub-millisecond latency for frequently accessed data, such as 'Your company runs a real-time analytics dashboard that requires consistent low-latency reads on blobs. Which tier minimizes latency?' would make Premium correct.
Why candidates choose this
Candidates may assume 'Premium' implies better performance for all scenarios, overlooking that it is optimized for high-frequency access and is not cost-effective for rarely accessed data.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose Archive tier thinking it is the cheapest option for rarely accessed data, but they overlook the critical requirement for 'within seconds' availability, which Archive cannot provide without a time-consuming rehydration process.
Detailed technical explanation
How to think about this question
Azure Blob Storage access tiers are managed at the blob level via the x-ms-access-tier header. Cool tier offers a 30-day early deletion penalty for blobs moved to Cool and then deleted, but this is irrelevant here as the data is rarely accessed. Under the hood, Cool tier uses lower-cost HDD-based storage with the same REST API latency as Hot tier, ensuring sub-second reads without rehydration. In a real-world scenario, if the reports were accessed only quarterly, Cool tier balances cost and availability perfectly, whereas Archive would require a rehydration step (changing tier to Cool or Hot) that could take hours.
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 |
