Difficulty: MediumAzure Regions, Availability Zones, and Region Pairs

A media streaming startup hosts its video transcoding workload in the West US Azure region. To prepare for a potential catastrophe that could affect the entire West US region, the IT department must select a deployment strategy that guarantees data replication to a secondary region located at least 300 miles away, while ensuring the data remains within the same country for regulatory compliance. Which Azure capability naturally satisfies these design requirements?

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

Answer

Azure Region Pairs
The correct answer is Azure Region Pairs. Azure designates a paired region within the same geographic boundary (e.g., the United States) located at least 300 miles away. This design ensures that regional disasters do not impact both regions simultaneously, while satisfying strict data residency regulations by keeping the data in the same country.

Step-by-Step Solution

1
Analyze the core requirements: protection against region-wide outages, geographical separation of at least 300 miles, and maintaining data residency within the same country.
The requirements demand a cross-region disaster recovery solution that respects country-level boundaries.
This filters out single-region high-availability options.
2
Evaluate the architectural features of Azure Region Pairs.
Azure automatically pairs regions within the same geography (except Brazil South) at a distance of at least 300 miles.
This matches both the replication distance and the regulatory compliance parameters.
