You are migrating a business critical application from your local data center into Google Cloud. As part of your high-availability strategy, you want to ensure that any data used by the application will be immediately available if a zonal failure occurs. What should you do?

Show Suggested Answer Hide Answer
Suggested Answer: D

as the instances (normal or preemptible) would be terminated and relaunched if the health check fails either due to application not configured properly or the instances firewall do not allow health check to happen.

GCP provides health check systems that connect to virtual machine (VM) instances on a configurable, periodic basis. Each connection attempt is called a probe. GCP records the success or failure of each probe.

Health checks and load balancers work together. Based on a configurable number of sequential successful or failed probes, GCP computes an overall health state for each VM in the load balancer. VMs that respond successfully for the configured number of times are considered healthy. VMs that fail to respond successfully for a separate number of times are unhealthy.

GCP uses the overall health state of each VM to determine its eligibility for receiving new requests. In addition to being able to configure probe frequency and health state thresholds, you can configure the criteria that define a successful probe.

Wait, we're supposed to choose an answer? I thought this was just a trivia quiz about cloud storage. Oops!

C) Store the application data on a regional persistent disk. Create a snapshot schedule for the disk. If an outage occurs, create a new disk from the most recent snapshot and attach it to a new VM in another zone.

Option A looks good, but creating snapshots on a schedule is a bit overkill. I'd stick with option C.

Haha, remember that time I lost all my data because I didn't have a backup? Good times, good times.

I'd go with option D. It's simpler and doesn't require creating snapshots, which can be a hassle to manage.

Option C seems like the way to go. Regional persistent disks ensure high availability in case of a zonal failure.

I think option A is the best choice because it allows for quick recovery by creating a new disk from the most recent snapshot.
