Zorluk: KolayDeveloping Procedures for Business Continuity and Disaster Recovery Validation

An organization plans to validate its disaster recovery (DR) failover procedure by spinning up application workloads in a secondary Google Cloud region. What essential step must the cloud architecture team complete prior to executing the failover drill to prevent deployment failures caused by resource limits?

  1. Pre-verify and request regional Compute Engine resource quota increases in the destination disaster recovery region.Cevap
  2. B
    Migrate the primary relational database to Cloud Spanner to eliminate regional compute quota restrictions.
  3. C
    Adopt a cold-standby backup-and-restore strategy to guarantee a zero Recovery Point Objective (RPO) during the drill.
  4. D
    Deploy high-availability Dedicated Interconnect connections to automatically raise Compute Engine quotas during failover.

Cevap

Pre-verifying and requesting regional Compute Engine resource quota increases in the secondary region prior to initiating the failover test.
Pre-verifying and requesting regional quota increases in the target disaster recovery region ensures that Google Cloud will allow the necessary Compute Engine instances and resources to be provisioned during a failover drill without hitting default quota limits.

Adım Adım Çözüm

1
Analyze DR failover requirements for compute resources in the destination region.
Identified that scaling up workload instances in a secondary region requires sufficient available Compute Engine CPU and RAM quotas.
Google Cloud quotas are enforced per region to protect system resources.
2
Check target region quotas against estimated DR resource demands prior to testing.
Discovered that default regional quotas might restrict simultaneous instance creation during full failover.
Quota approval requests take time to process and must be completed before the validation drill starts.
3
Submit quota increase requests in advance for the DR destination region.
Guaranteed capacity availability for seamless instance provisioning during the failover simulation.
Pre-verifying quota limits ensures that the DR validation drill tests actual recovery logic rather than failing due to platform capacity limits.
