Full Answer
B.To provide disaster recovery by replicating data to a region at least 300 miles away.✓ Correct
To provide disaster recovery by replicating data to a region at least 300 miles away.
Azure pairs every region with another region in the same geography (e.g., East US and West US). This ensures that if a massive disaster takes out an entire region, data is safely replicated to the paired region. Azure also prioritizes updating one region in a pair at a time to prevent bad updates from taking down both.
Common mistakes
Confusing Region Pairs with Availability Zones.
