You have an Azure subscription used for testing and development purposes only. The subscription contains Azure virtual machines that use unmanaged, standard hard disk drives (HOD).
You need to recommend a recovery strategy for the virtual machines if an Azure region fails for a sustained period. The recovery time objective (RTO) can be up to seven days. The solution must minimize costs.
What should you include in the recommendation?
A . Store the disks in a Standard_LRS storage account. If a disaster occurs, manually create the virtual machines by using Azure Resource Manager templates.
B . Store the disks in a Standard_LRS storage account. Configure Azure Site Recovery. If a failure occurs, initiate a manual failover.
C . Store the disks in a Standard_GRS storage account. Configure Azure Site Recovery. If a failure occurs, initiate a manual failover.
D . Store the disks in a Standard_GRS storage account If a disaster occurs, manually create the virtual machines by using Azure Resource Manager templates.
