Zorluk: ZorBlob, File, and Disk Storage Solutions

An enterprise e-commerce platform is migrating its containerized workloads to Azure Kubernetes Service (AKS) running on Linux nodes. You are designing the storage architecture to meet the following requirements:

* A shared file share is required to store product catalog assets. It must be mounted directly by multiple concurrent Linux pods, support the NFS v4.1 protocol, provide zone redundancy, and deliver sub-millisecond latency for metadata operations.
* A stateful database container requires a persistent volume that supports at least 25,00025,000 IOPS and sub-millisecond write latency, and must remain available even if a single Azure availability zone suffers an outage.

Which two storage configurations should you include in your design? (Select TWO.)

  1. Premium Azure Files share using the NFS v4.1 protocol configured with Zone-Redundant Storage (ZRS)Cevap
  2. Premium SSD v2 managed disks configured with Zone-Redundant Storage (ZRS)Cevap
  3. C
    Ultra Disk managed disks configured with Zone-Redundant Storage (ZRS)
  4. D
    Standard Azure Files share using the SMB protocol configured with Geo-Redundant Storage (GRS)

Cevap

Premium Azure Files share using the NFS v4.1 protocol configured with Zone-Redundant Storage (ZRS) and Premium SSD v2 managed disks configured with Zone-Redundant Storage (ZRS)
The required architecture must include a high-performance shared file system and a high-performance database persistent volume, both configured with Zone-Redundant Storage (ZRS). A Premium Azure Files share configured with NFS v4.1 and ZRS satisfies the file share requirement by supporting concurrent Linux pod mounting, low latency, and zone-redundant availability. Premium SSD v2 managed disks configured with ZRS satisfy the database requirement by supporting up to 80,000 IOPS and sub-millisecond latency while providing zone redundancy.

Adım Adım Çözüm

1
Evaluate the requirements for the shared file system: concurrent Linux pod mounting, NFS v4.1 protocol, zone redundancy, and sub-millisecond metadata latency.
Identify that Premium Azure Files configured with ZRS and NFS v4.1 fulfills all performance and accessibility requirements, as standard tiers do not support these performance levels or protocol configurations.
Premium Azure Files is designed for high-performance and low-latency workloads, offering NFS v4.1 support and ZRS.
2
Evaluate the database persistent volume requirements: 25,00025,000 IOPS, sub-millisecond write latency, and protection against a single zone outage.
Identify that Premium SSD v2 managed disks support ZRS and can scale up to 80,00080,000 IOPS and sub-millisecond latency, whereas Ultra Disk only supports LRS and cannot satisfy the zone failure protection requirement.
ZRS is required to survive a single availability zone failure at the storage layer, which rules out Ultra Disk.
