Which TWO are valid access tiers for Azure Blob Storage? (Choose two.)
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
Hot, Cool, and Archive are the three access tiers. Premium is a performance tier, not an access tier. Cold is not a standard tier.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Premium
Why it's wrong here
Premium is a performance tier, not an access tier, for Azure Blob Storage. It uses SSD-backed storage to deliver lower-latency and higher-throughput performance for enterprise workloads, and it is billed based on provisioned capacity rather than data access frequency. Because access tiers specifically classify data by how often it is read or written, Premium does not belong to the access-tier set.
- ✗
Cold
Why it's wrong here
Cold is not a standard access tier for general-purpose Blob Storage accounts in the scope of this exam. The classic set of Blob Storage access tiers consists of Hot, Cool, and Archive, with Cool being the entry point for infrequent access and Archive for long-term offline retention. Choosing Cold is incorrect because it is not one of the valid access-tier options recognized for Blob Storage.
- ✓
Cool
Why this is correct
Cool is a valid access tier designed for data that is infrequently accessed but still must be available immediately when needed. It provides lower storage costs than Hot while incurring higher access charges, making it suitable for backups, short-term retention, or disaster recovery files. Because Cool is one of the documented access tiers for Azure Blob Storage, it is a correct answer.
- ✗
Frozen
Why it's wrong here
Frozen is not an access tier in Azure Blob Storage and does not appear in Microsoft's documented tier list. The name may sound similar to a very low-temperature archive state, but Azure's Archive tier already supplies the lowest-cost offline storage option. Since Frozen does not exist as a defined tier, it cannot be a valid selection.
- ✓
Hot
Why this is correct
Hot is a valid access tier optimized for data that is accessed or modified frequently, such as content on active websites, analytics input, or files requiring immediate processing. It has the highest storage cost among the online tiers but the lowest access cost, aligning with high-read usage patterns. As a documented access tier, Hot is a correct answer.
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 |
