You are working on designing a solution that requires you to build an application that has disaster recovery capability and can withstand the loss of an entire region.
Identify the strategy that is not suitable for implementing this solution.

Answer options:

A.Use multiregional storage services.
B.Use a zonal resource, but snapshot data to a multiregional resource.
C.Use a zonal resource but manage own data replication to other regions as required.
D.Use a managed zonal resource.

Correct Answer: D
Option A is incorrect. Since you are using multiregional storage services, the application can withstand the loss of an entire r egion.
Option B is incorrect. Since you are taking a snapshot of data to a multiregional resource, the application can withstand the loss of an entire region.
Option C is incorrect. Although zonal resources are being used, data replication is being done to other regions. The application can withstand the loss of an entire region.
Option D is correct. Using “zonal resources only” will not be ideal as the application, in this case, will not be able to sustain regional failure.
