- A
Hot storage tier with geo-redundant storage (GRS)
Why wrong: Hot tier has the highest storage cost. Since data is rarely accessed, using Hot is not cost-effective. GRS provides geo-replication, but the tier choice is too expensive.
- B
Cool storage tier with geo-redundant storage (GRS)
Cool tier provides low storage cost for infrequently accessed data with immediate availability. GRS ensures geo-redundancy for disaster recovery at a moderate cost, meeting all requirements.
- C
Archive storage tier with read-access geo-redundant storage (RA-GRS)
Why wrong: Archive tier has the lowest storage cost but requires rehydration (hours) before data can be read. The requirement 'available within minutes' cannot be met with Archive.
- D
Premium storage tier with local redundant storage (LRS)
Why wrong: Premium storage is for high-performance scenarios and is very expensive. LRS provides only local redundancy, not geo-redundancy, failing the disaster recovery requirement.
Quick Answer
The answer is the Cool storage tier with geo-redundant storage (GRS). This combination is correct because Cool tier is specifically designed for infrequently accessed data—such as images and videos retrieved only a few times per year—offering significantly lower storage costs than the Hot tier while still providing retrieval within minutes when needed. GRS then replicates your data to a paired secondary region, ensuring geo-redundancy for disaster recovery without the higher cost of RA-GRS unless read access is required. On the AZ-204 exam, this scenario tests your ability to match storage tiers to access patterns and redundancy requirements, often appearing as a scenario-based multiple-choice question where the trap is choosing Archive tier (too slow for minutes-availability) or Locally Redundant Storage (no geo-redundancy). A useful memory tip: think “Cool for cool-down data, GRS for geo-safety”—if you need minutes, not hours, keep it out of Archive.
AZ-204 Develop for Azure storage Practice Question
This AZ-204 practice question tests your understanding of develop for azure 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.
You need to store large amounts of unstructured data (images and videos) that are accessed rarely (a few times per year) but must be available within minutes when requested. The data must be geo-redundant for disaster recovery. You want to minimize storage costs. Which storage tier and redundancy option should you choose?

Correct answer & explanation
Cool storage tier with geo-redundant storage (GRS)
The Cool storage tier is designed for data that is infrequently accessed (a few times per year) and stored for at least 30 days, offering lower storage costs than Hot tier while still providing low-latency retrieval within minutes. Geo-redundant storage (GRS) replicates data to a paired secondary region, ensuring disaster recovery with geo-redundancy. This combination meets the requirements of rare access, minutes-availability, geo-redundancy, and minimal cost.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Hot storage tier with geo-redundant storage (GRS)
Why it's wrong here
Hot tier has the highest storage cost. Since data is rarely accessed, using Hot is not cost-effective. GRS provides geo-replication, but the tier choice is too expensive.
- ✓
Cool storage tier with geo-redundant storage (GRS)
Why this is correct
Cool tier provides low storage cost for infrequently accessed data with immediate availability. GRS ensures geo-redundancy for disaster recovery at a moderate cost, meeting all requirements.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.

- ✗
Archive storage tier with read-access geo-redundant storage (RA-GRS)
Why it's wrong here
Archive tier has the lowest storage cost but requires rehydration (hours) before data can be read. The requirement 'available within minutes' cannot be met with Archive.
- ✗
Premium storage tier with local redundant storage (LRS)
Why it's wrong here
Premium storage is for high-performance scenarios and is very expensive. LRS provides only local redundancy, not geo-redundancy, failing the disaster recovery requirement.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the Archive tier's low storage cost with its high retrieval latency (hours), forgetting the requirement for data to be available within minutes, or they overlook that GRS is sufficient for geo-redundancy without needing read-access (RA-GRS).
Trap categories for this question
Scenario analysis trap
Premium storage is for high-performance scenarios and is very expensive. LRS provides only local redundancy, not geo-redundancy, failing the disaster recovery requirement.
Detailed technical explanation
How to think about this question
Azure Blob Storage access tiers (Hot, Cool, Archive) are billed differently: Hot has higher storage cost but no retrieval cost, Cool has lower storage cost with a retrieval cost per GB, and Archive has the lowest storage cost but significant retrieval time and cost. GRS replicates data synchronously within the primary region and asynchronously to a secondary region, ensuring durability even in a regional disaster. The Cool tier's 30-day minimum storage duration aligns with the 'few times per year' access pattern, and retrieval latency is typically under 15 minutes for blobs of any size.
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.

Variation 1. You are designing a solution to store large amounts of log data that will be queried infrequently but must be retained for regulatory purposes for 7 years. The logs are append-only and do not need to be modified. You need to choose a cost-effective storage option. Which three Azure capabilities should you consider? (Choose three.)
medium- A.Azure Blob Storage soft delete
- ✓ B.Azure Blob Storage lifecycle management policy
- ✓ C.Azure Blob Storage with Cool access tier
- D.Azure Table Storage
- ✓ E.Azure Blob Storage immutability policy
Why B: Azure Blob Storage with Cool or Archive access tier is cost-effective for infrequent access. Lifecycle management can automate tier transitions. Immutability policies ensure logs cannot be modified, meeting regulatory requirements. Soft delete is for accidental deletion, not immutability.
