[All Professional Cloud Architect Questions]

Your company is designing its application landscape on Compute Engine. Whenever a zonal outage occurs, the application should be restored in another zone as quickly as possible with the latest application data. You need to design the solution to meet this requirement. What should you do?

A. Create a snapshot schedule for the disk containing the application data. Whenever a zonal outage occurs, use the latest snapshot to restore the disk in the same zone.
B. Configure the Compute Engine instances with an instance template for the application, and use a regional persistent disk for the application data. Whenever a zonal outage occurs, use the instance template to spin up the application in another zone in the same region. Use the regional persistent disk for the application data.
C. Create a snapshot schedule for the disk containing the application data. Whenever a zonal outage occurs, use the latest snapshot to restore the disk in another zone within the same region.
D. Configure the Compute Engine instances with an instance template for the application, and use a regional persistent disk for the application data. Whenever a zonal outage occurs, use the instance template to spin up the application in another region. Use the regional persistent disk for the application data.

Answer is B, it only request zonal resiliency. Regional persistent disk is a storage option that provides synchronous replication of data between two zones in a region. Regional persistent disks can be a good building block to use when you implement HA services in Compute Engine. https://cloud.google.com/compute/docs/disks/high-availability-regional-persistent-disk

It is B. As for D: Spinning up the application in another region might be too geographically distant, leading to higher latency and potential issues.

Selected Answer: B

A regional persistent disk is designed to provide synchronous replication of data between two zones in the same region, ensuring that data remains available even if one zone is affected by an outage. By using an instance template along with a regional disk, you can quickly create new instances in an available zone during a zonal outage and attach the regional persistent disk to continue operations with the latest application data.

B - uses instance template which is ready for deploy. Option C requires manual configuration and this may take more time . But we need as quickly as possible .

Selected Answer: D

Option D suggests using the same approach as Option B but restoring the application in another region instead of the same region. This approach provides high availability and disaster recovery across regions, making it suitable for applications that require high RTOs and minimal data loss.

Of course it is answer B. I would like to understand who chooses the right answers in examtopics! Choosing here option D is completely wrong. This takes people less instructed to be mistaken.

Whenever a zonal outage occurs, use the instance template to spin up the application in another zone in the same region. Use the regional persistent disk for the application data.

B. In my opinion, I cannot use a regional disk in a different region!!! So, it can only be another zone in the same region. Therefore D must be wrong!

Answer B is Correct - since it talks about spin up application in different zone but same region. Whereas,D is incoorect , since its talking about spin up application in different region which is not our requirement.

If it is a regional persistent disk created in region A for example. If I start the compute engine instance in the region B, how am I going to use a regional disk from region A (another region)? I do not think it is possible. So answer D should be excluded. I do believe that the correct answer is B.
