What is the Recovery Time Objective (RTO) in the context of disaster recovery planning?
Answer: The maximum acceptable time to restore service after a disaster
RTO defines the maximum tolerable downtime — how quickly the service must be restored after a disaster occurs.
Which Cloud SQL feature provides automatic failover to a standby replica in case of a primary instance failure?
Answer: High Availability (HA) with failover replica
Cloud SQL High Availability creates a synchronous standby replica in the same region that automatically takes over if the primary fails.
An application requires a 99.99% availability SLA and must serve users across multiple GCP regions. Which load balancing configuration achieves this?
Answer: Global External HTTP(S) Load Balancer with multi-region backends
A Global External HTTP(S) Load Balancer with multi-region backend services provides the highest availability by routing to the nearest healthy region.
What is a key characteristic of a Warm Standby disaster recovery strategy?
Answer: A scaled-down version of the environment runs continuously and can scale up quickly
Warm Standby keeps a reduced-capacity version of the environment running, allowing faster recovery than a cold standby but at lower cost than hot standby.
Which GCP feature allows you to create scheduled, automated snapshots of Persistent Disks for backup?
Answer: Snapshot Schedules
Snapshot Schedules in Compute Engine automate the creation and retention of Persistent Disk snapshots on a defined schedule.
Which Cloud Spanner configuration provides the highest level of availability and global disaster recovery?
Answer: Multi-region instance
Cloud Spanner multi-region instances replicate data synchronously across multiple regions, providing 99.999% availability and regional DR.
