An administrator needs to configure snapshots for DRscenarios. The databases get refreshed on Friday nights regularly. The search service application re-indexes the new application on Saturday nights regularly. The remaining front-end and

middle tier VMs are static but do get minor version updates weekly.

Which two options should the administrator use to configure snapshots?

A. Create a schedule in a protection domain for all applicable VMs to snap daily with application consistency enabled with 6 days of retention and with no application consistency and 14 days local retention.

B. Create two consistency groups in a protection domain, one for front-end and middle tier apps with no application consistency, one for database and Search apps with application consistency, and apply the correct schedule to both groups.

C. Create one protection domain for all VMsin an application group with scheduled daily non-application consistent snapshots and another protection domain for all VMs in an application group with scheduled Friday. Saturday, Sunday application consistent snapshots.

D. Create a protection domain forall VMs
