An organization is executing a planned disaster recovery (DR) simulation for a critical web application hosted on Google Cloud. Arrange the standard operational steps in the correct chronological sequence to perform the failover and validation procedure.
- 1Verify and request necessary Compute Engine resource quotas in the secondary target region prior to initiating failover.
- 2Initiate data replication sync verification and promote the secondary database instance to primary status.
- 3Update Cloud DNS resource record sets to redirect incoming client traffic to the secondary region load balancer.
- 4Perform automated end-to-end health checks and validate application SLOs against baseline metrics in the failover environment.
Cevap
The correct operational sequence begins with verifying regional resource quotas, followed by database synchronization and promotion, then updating Cloud DNS routing to point to the failover region, and concludes with validating application health and SLO metrics.
The correct procedure follows a logical operational dependency chain: first ensure compute quota capacity in the destination region, promote the replicated database to ensure state consistency, update Cloud DNS to switch live traffic to the target environment, and finally conduct health and SLO checks to validate success.
