A company is deploying a new application on Compute Engine. They need to ensure that the application can automatically recover from a zone failure. What is the best approach?
Trap 1: Use a global load balancer in front of a single instance.
Global load balancing does not handle zone failure recovery.
Trap 2: Create a single VM in a single zone and rely on live migration.
Live migration handles maintenance, not zone failure.
Trap 3: Use Cloud Storage to store application state and restore from a…
Snapshots are for data recovery, not instance recovery.
- A
Create a managed instance group with instances in multiple zones.
MIG auto-heals and distributes across zones.
- B
Use a global load balancer in front of a single instance.
Why wrong: Global load balancing does not handle zone failure recovery.
- C
Create a single VM in a single zone and rely on live migration.
Why wrong: Live migration handles maintenance, not zone failure.
- D
Use Cloud Storage to store application state and restore from a snapshot.
Why wrong: Snapshots are for data recovery, not instance recovery.
