Difficulty: EasyAzure Regions, Availability Zones, and Region Pairs

A company is planning to deploy a web application and wants to ensure it is resilient against a local datacenter outage, such as a power or cooling failure, within the East US region. Which Azure architectural feature should they use to deploy the application's virtual machines across separate physical datacenters within this single region?

  1. Availability ZonesAnswer
  2. B
    Region Pairs
  3. C
    Resource Groups
  4. D
    Separate Azure Regions

Answer

Availability Zones
Availability Zones are physically separate datacenters within a single Azure region. Each zone has independent power, cooling, and networking infrastructure, which protects applications from a localized datacenter failure.

Step-by-Step Solution

1
Identify the primary requirement in the scenario.
The company needs protection against local datacenter failures (power, cooling) within a single Azure region (East US).
This establishes that the solution must provide high availability within the boundaries of a single region.
2
Evaluate the architectural options that provide physical datacenter redundancy within a single region.
Availability Zones consist of physically separate datacenters within a single region, each with independent power, cooling, and networking.
This matches the requirement for localized datacenter resilience while keeping resources within the same region.
