AZ-104 Implement and Manage Storage Practice Question
A legal team stores archived case files in Azure Blob Storage. The files are rarely read, but they must remain online and available immediately when needed. Which access tier should the administrator use?
⚠ Common exam trap
It's easy for candidates to choose Archive tier for 'archived' data without reading the 'available immediately' requirement, missing that Archive tier requires rehydration and cannot serve data on demand.
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 tier
The Cool tier is designed for data that is infrequently accessed but must remain online with low-latency retrieval. Archived case files that are rarely read but need immediate availability fit this profile, as Cool tier offers lower storage costs than Hot tier while still providing millisecond access times.
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 tier
Why it's wrong here
Hot tier is incorrect because it is designed for data that is accessed or modified frequently, and it incurs the highest storage cost among the online tiers. Archived legal case files are rarely read, so paying Hot tier rates for every byte stored would be unnecessarily expensive. While Hot tier does provide immediate access, that benefit is already available with Cool tier at a lower cost, making Hot tier the wrong choice for this scenario.
When this WOULD be correct
An administrator needs to store frequently accessed data, such as active customer transaction logs that are read and written multiple times per day, and requires low latency access.
- ✓
Cool tier
Why this is correct
Cool tier is correct because it is designed for data that is infrequently accessed but must remain instantly available when needed. Archived legal case files meet this pattern: they are rarely read, but when a request or legal proceeding requires them, there is no time to rehydrate from offline storage. Cool tier offers lower storage costs than Hot tier, while still keeping blobs online with immediate read access and no retrieval delay, making it the most cost-effective and practical choice.
- ✗
Archive tier
Why it's wrong here
Archive tier is incorrect because it is an offline tier that requires rehydration before any data can be read, and this process can take up to several hours. Legal archived case files may need to be produced quickly for e-discovery or court deadlines, so the long retrieval delay is not acceptable. Although Archive tier is the cheapest option, it is meant for data that is truly dormant and where a retrieval wait is tolerable, which does not apply here.
When this WOULD be correct
This option would be correct in a scenario where the legal team stores archived case files that are rarely accessed and can tolerate several hours of retrieval delay, such as for compliance data that only needs to be restored upon audit requests.
- ✗
Premium tier
Why it's wrong here
Premium tier is incorrect because it is optimized for high-frequency, low-latency access using high-performance SSD-backed storage. Archived legal case files are not accessed often enough to justify the significantly higher cost of Premium tier, which is intended for active workloads like interactive applications or real-time analytics. Using Premium tier for rarely opened case files would waste budget without providing any tangible benefit.
When this WOULD be correct
A question requiring ultra-low latency and high transaction rates for frequently accessed data, such as a real-time analytics pipeline or an interactive application with strict performance SLAs, would make the Premium tier 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.

✗Hot tierWrong answer — click to see why▾
Why this is wrong here
The Hot tier is designed for frequently accessed data with high transaction costs, making it unnecessarily expensive for rarely read archived case files that must remain online.
★ When this WOULD be the correct answer
An administrator needs to store frequently accessed data, such as active customer transaction logs that are read and written multiple times per day, and requires low latency access.
Why candidates choose this
Candidates may assume 'online and available immediately' requires the Hot tier, overlooking that Cool tier also provides immediate access with lower storage costs for infrequently accessed data.
✗Archive tierWrong answer — click to see why▾
Why this is wrong here
The Archive tier has the highest retrieval latency (up to 15 hours) and requires rehydration before data can be accessed, which violates the requirement that files must be 'available immediately when needed.'
★ When this WOULD be the correct answer
This option would be correct in a scenario where the legal team stores archived case files that are rarely accessed and can tolerate several hours of retrieval delay, such as for compliance data that only needs to be restored upon audit requests.
Why candidates choose this
Candidates may confuse 'archived' in the question with the 'Archive' tier name, assuming that archived files automatically belong in the Archive tier without considering the immediate availability requirement.
✗Premium tierWrong answer — click to see why▾
Why this is wrong here
The Premium tier is designed for low-latency, high-performance workloads with consistent access, not for rarely-read archived files. It incurs higher costs and is unnecessary for files that must remain online but are seldom accessed.
★ When this WOULD be the correct answer
A question requiring ultra-low latency and high transaction rates for frequently accessed data, such as a real-time analytics pipeline or an interactive application with strict performance SLAs, would make the Premium tier correct.
Why candidates choose this
Candidates may mistakenly believe 'Premium' implies better availability or online access, overlooking that the Cool tier already provides immediate availability at lower cost for infrequent access.

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 |
