An organization is designing a disaster recovery (DR) strategy for a critical transaction database. The solution must protect against a broad-scale regional outage, such as a major natural disaster, while ensuring that the replication data traffic stays on the Microsoft backbone network and adheres to national data residency regulations by remaining within the same country. Which Azure architectural concept should the organization utilize?
- AAzure Availability Zones, which replicate the application across three geographically separated regions within the same continent to ensure high availability.
- Azure Region Pairs, which provide automatic cross-region replication between two regions located within the same geographic boundary, typically separated by at least 300 miles.Answer
- CAzure Availability Sets, which group virtual machines within a single datacenter to guarantee recovery from a broad-scale regional disaster.
- DAzure Resource Groups, which automatically replicate all nested resources to a secondary region to ensure they inherit the resource group's location.
Answer
Azure Region Pairs, which provide automatic cross-region replication between two regions located within the same geographic boundary, typically separated by at least 300 miles.
Azure Region Pairs automatically pair two regions within the same geographic boundary (typically at least 300 miles apart) to enable disaster recovery replication while keeping traffic on the Microsoft backbone network and complying with national data residency requirements.
Step-by-Step Solution
Key Concept
Azure Region Pairs provide automatic cross-region replication and disaster recovery capability within the same geographic boundary.
