AeroTerra GeoServices is designing a business continuity solution for a seismic telemetry ingestion system. The system continuously writes incoming sensor data to an Azure Storage account.
The design must meet the following requirements:
- Recovery Point Objective (): Less than 15 minutes.
- Recovery Time Objective (): Less than 1 hour.
- Read Availability: The analytics application must have continuous read access to telemetry data, even during a primary region outage.
- Write Availability: Telemetry writes must be restored in a secondary region within the .
- Cost: Minimize costs by avoiding multi-region active-active write configurations.
To achieve this, the architect proposes using a Read-Access Geo-Redundant Storage (RA-GRS) account and performing a customer-managed failover in the event of a primary region disaster.
Which two statements correctly describe the data access capabilities and failover behavior for this storage configuration? (Select two.)
- Prior to initiating the failover, the secondary region endpoint is read-only, and any attempt to write data directly to the secondary region will fail.Cevap
- Upon completion of the customer-managed failover, the storage account replication type is automatically converted to Locally Redundant Storage (LRS) in the new primary region.Cevap
- CPrior to initiating the failover, the storage account supports active-active write operations across both the primary and secondary regions to balance the write load.
- DTo further reduce storage costs while maintaining regional disaster resilience, the storage account can be configured with Locally Redundant Storage (LRS) in the primary region.
