Google Associate Cloud Engineer Exam - Topic 8 Question 63 Discussion

Actual exam question for Google's Associate Cloud Engineer exam
Question #: 63
Topic #: 8
[All Associate Cloud Engineer Questions]

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, can you really just attach a zonal disk in another zone? Sounds risky.

I vaguely recall that zonal persistent disks are not ideal for high availability, so I’m leaning towards option C or D, but I can't remember the details.

I feel like I might be mixing up the zonal and regional disks. Didn't we practice a question where snapshots were crucial for recovery?

I think option D sounds right because it mentions using a regional persistent disk, which should help with availability across zones.

I remember we discussed the importance of using regional persistent disks for high availability, but I'm not sure if snapshots are necessary in this case.

This seems like a tricky question. I'll need to think carefully about the non-proprietary protocols that can collect layer 2 information without using SPAN.

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.
