Zorluk: OrtaAzure Regions, Availability Zones, and Region Pairs

A healthcare organization is planning to host its patient portal on Azure. The system must comply with local compliance policies requiring patient data to be stored within the same country. To protect against potential regional disasters, the organization also requires a disaster recovery solution that maintains data replication to a secondary location at least 300 miles away. Which Azure feature should the organization use to meet these requirements?

  2. B
    Azure Availability Zones
  3. C
    Azure Resource Groups
  4. D
    Availability Zones spanning across multiple separate geographical regions

Cevap

Azure Region Pairs
The correct answer is Azure Region Pairs. Azure Region Pairs link two regions within the same geographic boundary (such as a country) to meet data residency requirements. They are also physically separated by at least 300 miles to allow for disaster recovery in the event of a wide-scale regional outage.

Adım Adım Çözüm

1
Analyze the requirements: (1) Data residency limits (patient data must remain in the same country), (2) Disaster recovery protection (replicated secondary location), (3) Distance separation (at least 300 miles apart).
Identified the need for a cross-region replication strategy within a single country that has a minimum distance buffer.
This sets the criteria for selecting the correct Azure deployment model.
2
Evaluate Azure architectural components against these criteria.
Azure Region Pairs automatically pair two regions within the same geography (usually the same country) and separate them by at least 300 miles, satisfying all constraints. Availability Zones are limited to a single region and do not span regions, and Resource Groups are purely logical containers.
This rules out distractors and confirms the correct feature.
