Question

A large healthcare provider's primary electronic health record (EHR) application runs on Compute Engine instances with a Cloud SQL for PostgreSQL database, all located in the us-west1 region. A new regulatory mandate requires you to implement and document a business continuity plan (BCP). This plan must ensure that the EHR application can be fully recovered and operational in a different geographical region with a recovery time objective (RTO) of two hours and a recovery point objective (RPO) of 15 minutes. You need to design a disaster recovery strategy that meets these strict BCP requirements. What should you do?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Deploy active managed instance groups (MIGs) in both us-west1 and us-east1, fronted by a global external HTTP(S) Load Balancer. For the database, use a cross-region read replica in us-east1, and rely on load balancer... A managed instance group provides autoscaling, autohealing, and rolling updates for VMs. The external HTTP(S) Load Balancer distributes global web traffic with a single anycast IP. A load balancer distributes traffic across healthy backends in multiple zones for availability and scale. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
