Zorluk: OrtaAzure Regions, Availability Zones, and Region Pairs

An organization is designing the Azure architecture for a new IoT telemetry processing system. The architecture must meet two key requirements:

1. High availability within the primary deployment region to protect the system against localized power, cooling, or network failures at the datacenter level.
2. Disaster recovery capability to protect the system against a catastrophic regional outage, utilizing a secondary region located at least 300 miles away.

Which two Azure architectural features should the organization use to meet these requirements?

  1. Availability Zones within the primary regionCevap
  2. The designated Azure Region Pair for the primary regionCevap
  3. C
    Separate Resource Groups created in different geographical regions
  4. D
    Availability Zones configured to span across two different Azure regions

Cevap

Availability Zones within the primary region and the designated Azure Region Pair for the primary region
To protect against datacenter-level power, cooling, or network outages within the same region, you should use Availability Zones, which distribute workloads across isolated physical datacenters. For disaster recovery across a distance of at least 300 miles, you should use the designated Azure Region Pair, which is designed for cross-region replication and fault tolerance during catastrophic regional outages.

Adım Adım Çözüm

1
Analyze the first requirement: protection against localized power, cooling, or network failures at the datacenter level within a single region.
Identify that Availability Zones are physically separate datacenters within a single region, each equipped with independent power, cooling, and networking. This makes them the correct choice for localized datacenter-level redundancy.
This directly addresses the requirement for single-region high availability without crossing regional boundaries.
2
Analyze the second requirement: protection against a catastrophic regional outage using a secondary region located at least 300 miles away.
Identify that Azure Region Pairs are built specifically for regional disaster recovery, automatically replication-enabled, and spaced at least 300 miles apart.
This matches the disaster recovery requirement and geographical separation distance constraint.
3
Evaluate and eliminate the distractors.
Discard resource groups since they are logical containment boundaries and cannot span/replicate physically. Discard the concept of spanning Availability Zones across different regions because Availability Zones are strictly localized within a single region.
This confirms that only Availability Zones within the primary region and the designated Region Pair are the correct architectural choices.
