Question

Difficulty: MediumAzure Regions, Availability Zones, and Region Pairs

To design a resilient architecture in Microsoft Azure, you must understand the difference between high availability and disaster recovery. Determine if the following statement is true or false: Deploying an application across multiple Azure Availability Zones within a single region protects the application from a region-wide disaster, such as a major natural disaster that impacts the entire region.

Answer: Answer

Answer

False
The correct answer is False because Availability Zones are localized within a single region and cannot protect against region-wide disasters.

Step-by-Step Solution

1
Identify the scope of protection provided by Azure Availability Zones.
Availability Zones protect against datacenter-level failures (power, cooling, and networking outages) within a single Azure region.
Each zone is composed of one or more datacenters equipped with independent power, cooling, and networking.
2
Evaluate if Availability Zones protect against region-wide disasters.
No, since all Availability Zones of a region are located in the same geographic area, they are all vulnerable to a large-scale regional disaster (e.g., hurricanes, earthquakes, regional power grid failures).
Cross-region replication utilizing Azure Region Pairs is necessary to protect against region-wide disasters.

Key Concept

Azure Availability Zones provide protection against local datacenter outages within a single region, whereas Region Pairs provide protection against regional disasters.
