Zorluk: OrtaBlob, File, and Disk Storage Solutions

An organization is designing the storage infrastructure for a new containerized application workflow on Azure. The architecture must satisfy the following technical requirements:

- Provide a shared, POSIX-compliant file system for a cluster of Linux nodes that supports the NFS v4.1 protocol and can withstand the outage of a single Availability Zone within the primary Azure region.
- Provide block storage for a transaction-intensive database workload that requires consistent sub-millisecond disk write latencies.

Which two storage configurations should you recommend? (Select two.)

  1. Configure Azure Files Premium tier with Zone-Redundant Storage (ZRS) and the NFS protocol for the shared file systemCevap
  2. Configure Premium SSD v2 managed disks for the database workloadCevap
  3. C
    Configure Standard SSD managed disks for the database workload
  4. D
    Configure Azure Files Premium tier with Locally Redundant Storage (LRS) and the NFS protocol for the shared file system
  5. E
    Configure a Shared Access Signature (SAS) token with a five-year validity period for authentication to the NFS file share

Cevap

Configure Azure Files Premium tier with Zone-Redundant Storage (ZRS) using NFS, and configure Premium SSD v2 managed disks for the database workload.
Configuring Azure Files Premium tier with Zone-Redundant Storage (ZRS) using NFS provides a POSIX-compliant, zone-resilient shared file system that meets the Linux cluster requirements. Configuring Premium SSD v2 managed disks delivers the necessary low latency and high IOPS for transaction-intensive database workloads.

Adım Adım Çözüm

1
Evaluate the shared file system requirements.
The file system must be POSIX-compliant, support NFS v4.1, and tolerate a zone outage. Azure Files Premium tier supports NFS v4.1 and can use Zone-Redundant Storage (ZRS) to meet these needs.
Standard tier Azure Files does not support NFS, and LRS does not survive zone outages.
2
Evaluate database storage requirements.
The database needs consistent sub-millisecond disk write latencies. Premium SSD v2 managed disks provide the required IOPS and low-latency metrics.
Standard HDD and Standard SSD disks cannot guarantee sub-millisecond latencies.
3
Verify security and protocol compatibility.
Reject SAS token authentication since NFS file shares in Azure Files rely on network-level security and POSIX permissions rather than SAS tokens, and long-lived SAS tokens introduce risk.
Ensures the recommended solution is technically feasible and secure.

Anahtar Kavram

Azure storage design matching performance, protocol (NFS/SMB), and resiliency (LRS/ZRS) requirements to appropriate disk and file service configurations.
