Exam AZ900 Topics: architecture Difficulty: hard

A travel company's storage account uses geo-redundant storage (GRS). The architecture team wants to serve part of the application's read traffic from the copy in the secondary region during normal operations, without waiting for a disaster. What should the team do?

Options (Reading Mode) Click to filter discussion →
  1. A. Nothing — under GRS, applications can already read the secondary region's copy at any time
  2. B. Use read-access geo-redundant storage (RA-GRS), which makes the replicated data in the secondary region available for reads
  3. C. Trigger a storage account failover to the secondary region, then fail back after each batch of reads
  4. D. Switch to zone-redundant storage (ZRS), which serves reads from a second availability zone in the same region

Correct answer: Use read-access geo-redundant storage (RA-GRS), which makes the replicated data in the secondary region available for reads
