AZURE PHYSICAL INFRASTRUCTURE: REGIONS, AVAILABILITY
ZONES, AND DATA RESILIENCE|COMPLETE QUESTIONS WITH
VERIFIED ANSWERS (100% ACCURATE SOLUTIONS)
(2025/2026)
What is the starting point of Azure's physical infrastructure? Datacenters
What are Azure Regions? Geographical areas containing at least one, but potentially multiple,
nearby and networked datacenters.
What is the purpose of Azure Availability Zones? To provide physically separate datacenters
within a region that serve as isolation boundaries for resiliency.
How are Azure datacenters grouped? Into Azure Regions or Azure Availability Zones.
What is the significance of low-latency networks in Azure Regions? They ensure efficient
resource assignment and workload balancing within the region.
What types of services may only be available in certain Azure Regions? Specific VM sizes or
storage types.
What are the three categories of Azure services that support availability zones? Zonal services,
zone-redundant services, and non-regional services.
What is a region pair in Azure? A pairing of two Azure regions within the same geography, at
least 300 miles apart, for resource replication and disaster recovery.
What happens if a region in a pair is affected by a disaster? Services automatically fail over to
the other region in its region pair.
