Zorluk: ZorAzure Regions, Availability Zones, and Region Pairs

A healthcare organization is planning to host its patient management portal in Azure. The regulatory framework requires that all patient data remain within the national borders of Germany. At the same time, the infrastructure must remain resilient against localized datacenter failures (such as a power outage in a single facility) and regional-scale disasters. Which two statements represent valid architectural configurations that meet these requirements? (Select two.)

  1. Deploying virtual machine instances across multiple Availability Zones within the Germany West Central region protects the application from localized power or cooling outages.Cevap
  2. Replicating database backups to Germany North, the designated region pair for Germany West Central, ensures disaster recovery capabilities while maintaining data residency within Germany.Cevap
  3. C
    Configuring virtual machines to replicate between Availability Zones within Germany West Central serves as a regional disaster recovery (DR) solution in the event that the entire Germany West Central region becomes unavailable.
  4. D
    Deploying virtual machines across the Germany West Central and Germany North regions allows a single Availability Zone to span both regions to enable synchronous replication.

Cevap

Deploying virtual machine instances across multiple Availability Zones within the Germany West Central region protects the application from localized outages, and replicating database backups to Germany North (the region pair) ensures disaster recovery while maintaining data residency.
Deploying instances across multiple Availability Zones protects against localized failures (like power, cooling, or network outages in a single datacenter) because each zone is a physically separate facility within a region. Replicating data to a paired region (such as Germany North for Germany West Central) provides disaster recovery capabilities in the event of a region-wide outage, while keeping the data within the same country to satisfy data residency requirements.

Adım Adım Çözüm

1
Analyze high availability (HA) requirements within a single region.
Identify that deploying resources across Availability Zones protects against localized failures like power or cooling outages because each zone is a physically separate datacenter within the region.
To satisfy resilience against localized datacenter failures while keeping the service active.
2
Analyze disaster recovery (DR) and data residency requirements.
Identify that replication to a paired region within the same national boundary (Germany West Central to Germany North) provides regional DR without violating the data residency mandate.
To satisfy resilience against region-wide outages while complying with regulatory requirements.

Anahtar Kavram

Azure Regions, Availability Zones, and Region Pairs are designed to provide different levels of resilience (High Availability vs. Disaster Recovery) and meet data residency compliance requirements.
