Difficulty: EasyAzure Regions, Availability Zones, and Region Pairs

A company is designing a disaster recovery plan for a database hosted in the East US region. The company needs to replicate the database to a secondary region located at least 300 miles away to ensure business continuity in the event of a major outage affecting the entire primary region.

Which Azure feature represents this default secondary geographic relationship?

  1. Azure Region PairsAnswer
  2. B
    Azure Availability Zones
  3. C
    Resource Groups
  4. D
    A single Availability Zone spanning multiple regions

Answer

Azure Region Pairs
Azure Region Pairs is the correct answer because Azure automatically pairs regions within the same geography (such as East US and West US) at a distance of at least 300 miles. This relationship is specifically designed for disaster recovery, allowing services like Azure Storage to replicate data to a secondary region to protect against regional outages.

Step-by-Step Solution

1
Identify the goal of the company.
The company wants to replicate data to a secondary region located at least 300 miles away to recover from a primary regional outage.
This establishes that the requirement is for regional disaster recovery (DR) rather than local high availability (HA).
2
Select the Azure feature designed for cross-region disaster recovery at a distance.
Azure Region Pairs is the feature that links two regions within the same geography at a physical distance of at least 300 miles.
This relationship allows for automatic replication of certain services and provides isolated recovery environments during regional outages.

Key Concept

Azure Region Pairs are designated pairs of regions within the same geography located at least 300 miles apart to facilitate disaster recovery and regional resiliency.
