You are hosting an application from Compute Engine virtual machines (VMs) in us-central1-a. You want to adjust your design to support the failure of a single Compute Engine zone, eliminate downtime, and minimize cost. What should you do?

• A.- Create Compute Engine resources in us-central1-b.
  - Balance the load across both us-central1-a and us-central1-b.
• B.- Create a Managed Instance Group and specify us-central1-a as the zone.
  - Configure the Health Check with a short Health Interval.
• C.- Create an HTTP(S) Load Balancer.
  - Create one or more global forwarding rules to direct traffic to your VMs.
• D.- Perform regular backups of your application.
  - Create a Cloud Monitoring Alert and be notified if your application becomes unavailable.
  - Restore from backups when notified.
