Question

Difficulty: MediumAzure Regions, Availability Zones, and Region Pairs

An administrator is planning a disaster recovery strategy for applications deployed in Azure. The administrator wants to use Azure region pairs to ensure business continuity. Which of the following describes a key operational characteristic of Azure region pairs?

  1. A
    A region pair consists of multiple physically isolated datacenters connected by low-latency fiber within a single geographical region.
  2. Planned Azure platform updates are rolled out to paired regions sequentially, ensuring that only one region in a pair is updated at a time.Answer
  3. C
    Region pairs are primarily designed to achieve local high availability by hosting active-active application instances with zero latency.
  4. D
    Resources deployed in a region pair automatically inherit the location of their resource group and replicate across the pair by default.

Answer

Planned Azure platform updates are rolled out to paired regions sequentially, ensuring that only one region in a pair is updated at a time.
The correct option is correct because Azure performs planned updates sequentially across paired regions. This ensures that a platform update issue does not cause downtime in both regions of the pair simultaneously, maintaining availability for workloads configured for cross-region disaster recovery.

Step-by-Step Solution

1
Analyze the requirement for Azure region pairs, which are designed to support disaster recovery and business continuity.
Identified that region pairs consist of two separate geographic regions located within the same geography.
Understanding the scale and scope of region pairs is necessary to distinguish them from availability zones.
2
Evaluate the operational rules for region updates and recovery prioritization.
Determined that Azure updates only one region in a pair at any given time to prevent concurrent outages.
This is a key platform resilience mechanism to ensure one region remains online while the other undergoes planned maintenance.
3
Identify the correct option that matches the sequential update behavior, and eliminate options that confuse region pairs with Availability Zones or assume automatic resource group location inheritance.
Concluded that the statement about sequential platform updates is correct, and all other choices represent common misconceptions.
Completes the selection process by verifying that wrong options map to common architectural and organizational errors.
