An online media company is designing a new streaming platform in Azure. To ensure high availability, they want to protect their application from localized datacenter failures (such as power or cooling outages) within their chosen region. Additionally, they must implement a disaster recovery plan that replicates critical data to a secondary region located at least 300 miles away. Which two Azure architectural features should they use to satisfy these requirements? (Select TWO).
- Availability Zones to host application instances across unique physical locations with independent power, cooling, and networking within a single regionAnswer
- Region Pairs to replicate data and host recovery services in a secondary region located hundreds of miles away from the primary regionAnswer
- CAvailability Sets to deploy virtual machines across different geographic regions to provide protection against regional disasters
- DResource Group locations to automatically replicate and synchronize all resource data to a secondary region for disaster recovery
Answer
Availability Zones and Region Pairs
The correct options are Availability Zones and Region Pairs. Availability Zones provide high availability within a region by distributing resources across physically isolated datacenters. Region Pairs provide disaster recovery by pairing regions that are located at least 300 miles apart, facilitating cross-region replication and backup.
Step-by-Step Solution
Key Concept
Azure Availability Zones protect against datacenter failures within a region, while Azure Region Pairs provide replication and disaster recovery across regions separated by at least 300 miles.
