Zorluk: OrtaAzure Regions, Availability Zones, and Region Pairs

An organization is designing a critical web application on Azure. The application must meet two key requirements:

1. It must remain online even if an entire datacenter facility within the primary region experiences a power or cooling failure.
2. In the event of a catastrophic disaster affecting the entire primary region, the application must be restorable in a secondary region that is at least 300 miles away, while ensuring that Azure platform updates are never applied to both regions simultaneously.

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

  1. A
    Resource Groups for datacenter failure protection, and Azure Region Pairs for disaster recovery
  2. B
    Availability Zones for datacenter failure protection, and Azure Edge Zones for disaster recovery
  3. Availability Zones for datacenter failure protection, and Azure Region Pairs for disaster recoveryCevap
  4. D
    Availability Sets for datacenter failure protection, and Resource Groups for disaster recovery

Cevap

Availability Zones for datacenter failure protection, and Azure Region Pairs for disaster recovery
The correct option is the choice specifying Availability Zones and Azure Region Pairs. Availability Zones protect applications from datacenter-level failures within a single region because each zone consists of one or more datacenters equipped with independent power, cooling, and networking. Azure Region Pairs provide disaster recovery across regions separated by at least 300 miles, with the unique advantage that Azure schedules platform updates sequentially across paired regions to prevent simultaneous downtime.

Adım Adım Çözüm

1
Analyze the first requirement: protection against an entire datacenter failure within a single region.
Identify that Availability Zones consist of one or more physical datacenters with independent power, cooling, and networking within a region, making them the correct choice to survive datacenter outages.
Availability Sets only protect against rack-level failures within a single datacenter, and Resource Groups are logical boundaries, not physical ones.
2
Analyze the second requirement: disaster recovery to a secondary region at least 300 miles away with sequential updates.
Identify that Azure Region Pairs are designed specifically for regional disaster recovery, spanning at least 300 miles of separation and receiving sequential Azure platform updates to avoid concurrent downtime.
Other features like Edge Zones are for edge computing/low-latency services, and Resource Groups have no geographic replication features.
