Zorluk: OrtaData Redundancy and High Availability

An organization is designing a shared storage solution on Azure for a medical imaging application called MediSync. The application requires access via the SMB protocol and demands sub-millisecond storage latency for all read and write operations. Additionally, the storage solution must remain fully operational even if a single physical datacenter within the primary Azure region suffers a power outage. Which storage account tier and redundancy configuration should you recommend?

  1. A
    Premium tier configured with Locally Redundant Storage (LRS)
  2. B
    Premium tier configured with Geo-Redundant Storage (GRS)
  3. Premium tier configured with Zone-Redundant Storage (ZRS)Cevap
  4. D
    Standard tier configured with Geo-Redundant Storage (GRS)

Cevap

Premium tier configured with Zone-Redundant Storage (ZRS)
The correct option is the Premium tier configured with Zone-Redundant Storage (ZRS). The Premium tier is required because Azure Files requires SSD storage to deliver sub-millisecond latency. Zone-Redundant Storage (ZRS) replicates data synchronously across three availability zones within the primary region, ensuring the share remains available during a datacenter outage.

Adım Adım Çözüm

1
Determine the required performance tier
Premium tier is selected
The application requires sub-millisecond latency, which is only supported by Premium Azure Files (SSD-backed) rather than Standard Azure Files (HDD-backed).
2
Evaluate the resiliency requirement against zone failure
Zone-Redundant Storage (ZRS) is required
To survive a physical datacenter outage within the primary region, data must be replicated across separate Availability Zones, which requires ZRS.
3
Verify replication capability for the selected tier
Premium tier with ZRS is a valid configuration
Azure Premium Files only supports LRS and ZRS. Geo-redundant storage (GRS/GZRS) is not supported for Premium file shares.
