Question-41: A deployment area for Google Cloud resources that is contained inside a region is referred to as a zone. Within a region, a zone need to be regarded as a single potential failure domain. Within each region of Google Cloud, there are three to four deployment areas that map to clusters of data centers that have distinct physical infrastructure (i.e., power, cooling, and networking). These areas are referred to as zones by Google, while other cloud service providers commonly refer to them as availability zones. The application landscape at your organization is now being designed using Compute Engine. Whenever there is an outage in one zone, the application has to be restored in another zone as soon as possible, using the most recent data from the original zone. You are going to have to develop the solution such that it can fulfill this criterion. What action should you take?
A. Establish a timetable for the creation of snapshots on the disc that stores the application's data. Utilize the most recent snapshot to restore the disc that is located in the same zone whenever a zonal outage occurs.
B. Configure the instances of Compute Engine using an instance template that is specific to the application, and make use of a regional persistent disc for the data that pertains to the application. Make use of the instance template in the event that a zonal outage happens so that the application may be spun up in another zone within the same region. Make use of the persistent disc at the regional location for the application data.
C. Establish a timetable for the creation of snapshots on the disc that stores the application's data. When there is a problem with one of the zones in a region, utilise the most recent snapshot to restore the disc in one of the other zones in that region.
D. Configure the instances of Compute Engine using an instance template tailored to the application, and make use of a regional persistent disc for the data belonging to the application. Make advantage of the instance template in order to set up the application in a different area if a zonal outage happens. Make use of the persistent disc at the regional location for the application data.

: 2 Explanation: Request zonal resiliency. A storage option known as regional persistent disc allows for the synchronous replication of data between any two zones that are located within the same region. When it comes to the implementation of HA services in Compute Engine, regional persistent discs can be a useful building block to use. The data for the application should be stored on a regional persistent disk, and the Compute Engine instances should be configured with an instance template specific to the application. Make use of the instance template in the event that a zonal outage happens so that the application may be spun up in another zone within the same region. Make use of the persistent disc at the regional location for the application data. There is no need to relocate to a different region. This will almost certainly result in an increase in the latency experienced by some customers.
