Google Cloud Certified High Availability and Disaster Recovery

Question 1

What is the Recovery Time Objective (RTO) in the context of disaster recovery planning?

Accepted 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.

Question 2

Which Cloud SQL feature provides automatic failover to a standby replica in case of a primary instance failure?

Accepted Answer

High Availability (HA) with failover replica

Answer

Cloud SQL High Availability creates a synchronous standby replica in the same region that automatically takes over if the primary fails.

Question 3

An application requires a 99.99% availability SLA and must serve users across multiple GCP regions. Which load balancing configuration achieves this?

Accepted Answer

Global External HTTP(S) Load Balancer with multi-region backends

Answer

A Global External HTTP(S) Load Balancer with multi-region backend services provides the highest availability by routing to the nearest healthy region.

Question 4

What is a key characteristic of a Warm Standby disaster recovery strategy?

Accepted 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.
