Zorluk: OrtaAzure Regions, Availability Zones, and Region Pairs

A company is planning to deploy a web application on Azure virtual machines. The design requirements specify that the application must remain online even if a power or cooling failure causes an outage at an entire datacenter facility. At the same time, network latency between the virtual machines must be kept to a minimum.

Which Azure architectural feature should the company use to meet these requirements?

  1. A
    Azure Region Pairs
  2. B
    Separate Resource Groups in different regions
  3. Availability ZonesCevap
  4. D
    Azure Edge Zones

Cevap

Availability Zones
Availability Zones are correct because they offer physical isolation within the same Azure region, providing independent power, cooling, and networking. This layout protects virtual machine workloads from a single datacenter outage while keeping network latency to a minimum since all zones reside within the same geographical region.

Adım Adım Çözüm

1
Analyze the requirement for low latency and protection against datacenter-level power or cooling outages.
Identify that the solution must reside within a single region to keep latency minimal, while using physically isolated infrastructure.
Regional separation (such as Region Pairs) increases latency, and logical boundaries (such as Resource Groups) do not provide physical isolation.
2
Compare Availability Zones against the requirements.
Confirm that Availability Zones provide separate physical locations (with independent power, cooling, and networking) within the same region.
This architecture protects against single-facility failures while maintaining low latency.

Anahtar Kavram

Azure Availability Zones provide high availability within a region by isolating resources across separate physical datacenters with independent power, cooling, and networking.
