AZ-204 Practice Question: Connect to and consume Azure services and third-party services
You are developing an application that needs to store and retrieve large binary objects (up to 5 TB) in Azure Blob Storage. The application requires the ability to access data from any URL via HTTP/HTTPS. Which Blob Storage access tier should you use?
⚠ Common exam trap
Watch out — candidates often confuse the Archive tier's low storage cost with suitability for large objects, forgetting that Archive requires manual rehydration (which can take hours) before data can be accessed via HTTP/HTTPS, making it incompatible with the requirement for immediate URL-based access.
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
The Hot access tier is optimized for frequent read and write access to data, supports objects up to 5 TB, and allows access via HTTP/HTTPS from any URL. It is the only tier that combines low-latency access, high throughput, and public internet accessibility without requiring rehydration or special permissions, making it suitable for general-purpose blob storage scenarios.
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 this is correct
The Hot storage tier is specifically designed for frequently accessed data that requires instant retrieval capabilities via HTTP/HTTPS. It offers the lowest access costs and highest availability among the standard tiers, making it ideal for active datasets and applications where immediate data access is critical for user experience or operational efficiency. While its storage cost per GB is higher than Cool or Archive, its low transaction costs make it the most cost-effective choice for high-access patterns.
- ✗
Archive
Why it's wrong here
The Archive storage tier is optimized for rarely accessed data with flexible latency requirements, typically measured in hours. It boasts the lowest storage costs but incurs significantly higher data retrieval costs and latency, requiring a rehydration process before data can be accessed. This tier is unsuitable for applications demanding instant data access, as its primary purpose is long-term, cost-effective data retention for compliance or backup scenarios.
- ✗
Cool
Why it's wrong here
The Cool storage tier is a cost-effective option for infrequently accessed data that still requires rapid access, though with slightly higher latency and access costs compared to the Hot tier. It is suitable for data that is accessed at least once a month, such as short-term backups or older datasets, and has a minimum retention period of 30 days. Its balance between storage cost and access speed makes it a middle ground, but not optimal for truly frequent, instant retrieval.
- ✗
Premium
Why it's wrong here
The Premium storage tier is engineered for high-performance block blob workloads demanding very low, consistent latency and high transaction rates, typically in single-digit milliseconds. While it provides superior performance, its significantly higher storage and transaction costs make it overkill for general-purpose storage needs unless the application explicitly requires such extreme I/O capabilities. For most standard 'store and retrieve' scenarios, the Hot tier offers sufficient performance at a more economical price point.
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 |
