A company is planning to deploy a critical web application to Azure. The application must meet the following requirements:
- Minimize the impact of power or cooling failures within a single datacenter without replicating data to a different region.
- Ensure that a copy of the application data is stored in a secondary region located hundreds of miles away to protect against a regional disaster.
Which two Azure architectural features should the company use to meet these requirements? (Select two).
- Availability Zones to protect the application from datacenter-level power outages within the same regionAnswer
- Region Pairs to replicate data to a secondary region located hundreds of miles away for disaster recoveryAnswer
- CResource Groups to automatically replicate application data to a secondary region
- DAvailability Zones to replicate data across different geographical regions to satisfy data residency laws
Answer
Availability Zones to protect the application from datacenter-level power outages within the same region AND Region Pairs to replicate data to a secondary region located hundreds of miles away for disaster recovery
Availability Zones provide protection against localized datacenter failures (power, cooling, network) within a single region, satisfying the first requirement. Region Pairs provide geographical separation of at least 300 miles, satisfying the second requirement for disaster recovery.
Step-by-Step Solution
Key Concept
Azure Availability Zones provide local datacenter-level resiliency within a single region, while Azure Region Pairs provide regional-level disaster recovery across regions separated by hundreds of miles.
