Answer: 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.
The correct answer is B. This option involves configuring Compute Engine instances with an instance template for the application and using a regional persistent disk for the application data. In the event of a zonal outage, the instance template can be used to quickly spin up the application in another zone within the same region, utilizing the regional persistent disk. This ensures that the latest application data is available and minimizes downtime. Options A and C involve snapshots, which can take longer to restore and are less efficient in providing quick recovery. Option D incorrectly suggests restoring the application in another region, which is not aligned with the requirement of zonal recovery within the same region.

Your company is designing its cloud-based application landscape on Google Compute Engine. The business requirement is that whenever a zonal outage occurs, the application should be restored in another zone within the same region as quickly as possible, utilizing the latest available application data. You are tasked with designing a solution to meet this requirement efficiently. 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.
