Zorluk: ZorAzure Storage Accounts, Blob, Disk, Files, and Storage Tiers

A financial services firm is designing a hybrid data storage solution with the following requirements:
- A shared file repository must be concurrently accessible via the SMB protocol from both on-premises servers and Azure Virtual Machines.
- Historical transaction reports must be retained for seven years at the lowest possible storage cost; these reports are rarely accessed but must be available for immediate online retrieval within seconds when audited.

Which combination of Azure storage services and storage tiers best meets these requirements while minimizing operational overhead and costs?

  1. Azure Files for the shared repository, and Azure Blob Storage configured with the Cold access tier for the transaction reports.Cevap
  2. B
    Azure Files for the shared repository, and Azure Blob Storage configured with the Archive access tier for the transaction reports.
  3. C
    Azure Disk Storage for the shared repository, and Azure Blob Storage configured with the Cold access tier for the transaction reports.
  4. D
    Azure Blob Storage with the Hot access tier for the shared repository, and Azure Disk Storage for the transaction reports.

Cevap

Azure Files for the shared repository, and Azure Blob Storage configured with the Cold access tier for the transaction reports.
Azure Files provides a fully managed SMB file share that can be mounted concurrently on-premises and in Azure VMs, meeting the first requirement. The Cold tier in Azure Blob Storage provides the lowest possible storage cost for online storage, keeping the data immediately accessible within seconds/milliseconds without requiring the multi-hour rehydration process associated with the Archive tier.

Adım Adım Çözüm

1
Evaluate the sharing protocol and concurrency requirements.
Azure Files is identified as the appropriate service because it natively supports concurrent SMB access for both on-premises servers and Azure Virtual Machines as a fully managed service.
Azure Disk Storage is restricted to VM attachment, and Azure Blob Storage uses REST APIs rather than standard SMB for file shares.
2
Analyze the retrieval time constraints for the archived reports.
The Archive access tier is ruled out because it requires hours for rehydration, whereas the reports must be available within seconds.
The scenario specifies that reports must be available for immediate online retrieval.
3
Determine the most cost-effective online storage tier.
Azure Blob Storage with the Cold access tier is selected because it is cheaper than Hot and Cool tiers for storage cost while maintaining immediate (millisecond/second level) online availability.
This minimizes the cost of storing rarely accessed data while meeting the immediate retrieval requirement.
