Difficulty: EasyAzure Regions, Availability Zones, and Region Pairs

A company is configuring a storage account in Azure. They want to ensure that their data is automatically replicated to a secondary region located at least 300 miles away, while ensuring the data remains within the same geography for compliance. Which Azure concept automatically pairs regions to support this replication requirement?

  1. Azure Region PairsAnswer
  2. B
    Azure Availability Zones
  3. C
    Azure Availability Sets
  4. D
    Azure Resource Groups

Answer

Azure Region Pairs
The correct answer is the concept of Azure Region Pairs. Azure automatically pairs regions within the same geography (such as East US and West US) to provide automatic replication for services like Geo-Redundant Storage (GRS). These pairs are typically separated by at least 300 miles to minimize the likelihood of a single disaster impacting both regions, while still meeting residency requirements.

Step-by-Step Solution

1
Identify the primary requirement which is replication to a secondary region at least 300 miles away.
Determined that the solution must involve cross-region replication for disaster recovery.
Replication across regions separated by a significant distance is a key aspect of geographic redundancy.
2
Identify which Azure component automatically links two regions within the same geography for this purpose.
Azure Region Pairs is the mechanism that defines these relationships.
Region pairs are pre-defined by Azure to facilitate default replication while ensuring regulatory compliance is maintained within the same geographical boundary.
