Zorluk: KolayDeveloping Procedures for Business Continuity and Disaster Recovery Validation

A company is designing a disaster recovery (DR) validation procedure for a critical database running on Google Cloud. To ensure business continuity without disrupting active users during DR drills, the team needs to test regional failover and data restoration capabilities safely. Which procedure should the Cloud Architect recommend?

  1. Create an isolated test environment in the DR region using point-in-time database snapshots to validate recovery steps without impacting live production data.Cevap
  2. B
    Redirect live production user traffic to an unverified secondary region during peak hours without requesting compute quota increases beforehand.
  3. C
    Use a cold-standby restoration procedure from nightly backups to meet a strict zero Recovery Point Objective (RPO) requirement.
  4. D
    Replace database asynchronous replication with a Dedicated Interconnect connection to automatically trigger regional DR failovers.

Cevap

Create an isolated test environment in the DR region using point-in-time database snapshots to validate recovery steps without impacting live production data.
The procedure recommending an isolated test environment in the DR region using point-in-time database snapshots ensures full validation of restoration scripts and application readiness without putting live production operations or data integrity at risk.

Adım Adım Çözüm

1
Identify the primary requirement for DR validation
The validation process must test recovery procedures and data restoration safely without disrupting production systems.
DR testing should isolate test workloads from live user traffic to avoid accidental downtime or data corruption.
2
Evaluate the safest validation strategy
Restoring database snapshots into a separate, isolated environment in the secondary region allows full execution of recovery validation scripts.
Using isolated environments isolates test failures and guarantees production continuity.
