A company is designing an Azure Storage solution for an application that requires extremely low latency and high transaction rates for frequently accessed data. The data must be accessible via both Blob and File storage protocols. You need to recommend the most appropriate storage account type and access tier.
- AGeneral-purpose v1 storage account with Cool access tier.
- BBlock Blob storage account with Premium access tier.
- CGeneral-purpose v2 storage account with Hot access tier.
- DPremium block blob storage account with Hot access tier.
Show answer & explanationAnswer & explanation
Correct answer: C. General-purpose v2 storage account with Hot access tier.
General-purpose v2 (GPv2) storage accounts support both Blob and File storage, offering the flexibility required. The Hot access tier provides the lowest latency and highest transaction rates for frequently accessed data, aligning with the application's performance requirements. Premium Block Blob storage accounts are optimized for very high transaction rates and low latency but only support block blobs, not Azure Files directly within the same account.
Why the other options are wrong
- A. GPv1 is a legacy account type with fewer features and higher costs compared to GPv2, and the Cool tier is for less frequently accessed data.
- B. Block Blob storage accounts only support block blobs, not Azure Files, and the Premium tier is a performance feature, not a separate access tier for block blobs in the same way Hot/Cool/Archive are.
- D. Premium block blob storage accounts only support block blobs; they do not support Azure Files directly within the same account, failing to meet the dual protocol requirement.
General-purpose v2 (GPv2) Storage Account
General-purpose v2 (GPv2) storage accounts are the recommended storage account type for most scenarios, offering the latest Azure Storage features and supporting all storage services (Blobs, Files, Queues, Tables) with various access tiers.
- Supports Blobs, Files, Queues, and Tables.
- Offers Hot, Cool, and Archive access tiers for Blob storage.
- Recommended for most workloads due to feature set and cost efficiency.
- Can be used with Azure Files Premium for high-performance file shares.
