An enterprise organization is preparing a quarterly disaster recovery (DR) simulation to test the failover of a critical web application from its primary GCP region to a secondary region. During previous tests, spinning up secondary compute instances failed because the target region lacked sufficient resource capacity allocations. Which procedure should the Cloud Architect incorporate into the disaster recovery validation workflow to ensure the failover drill succeeds?
- Submit and verify regional quota increase requests for required compute resources in the secondary region prior to initiating the failover drill.Cevap
- BWait to submit quota increase requests until the failover drill starts to ensure resources are not allocated during baseline operations.
- CSwitch the database disaster recovery architecture from asynchronous replication to a cold-standby backup restore procedure to bypass compute quotas.
- DReplace the high-bandwidth Dedicated Interconnect with Cloud VPN tunnels immediately before failover testing to bypass regional compute limits.
Cevap
Submit and verify regional quota increase requests for required compute resources in the secondary region prior to initiating the failover drill.
Submitting and verifying regional quota increases before starting a disaster recovery drill ensures that Google Cloud allocates sufficient quota limits for secondary compute resources, allowing automated failover scripts to complete without quota errors.
Adım Adım Çözüm
Anahtar Kavram
Disaster recovery validation procedures must include pre-drill verification of target region resource quotas to guarantee successful failover capacity.
