only within the non-preferred site

B.

only across both sites

C.

only within the preferred site

D.

within and across both sites

Question 3

Virtual machines will be live migrated and all storage objects residing on this host will migrate to another host that is not in maintenance mode.

C.

Virtual machines will be live migrated to another host not in maintenance mode and storage objects will not migrate regardless of policy and state.

D.

Virtual machines will not be live migrated to another host not in maintenance mode and storage objects will be migrated if it is required to be accessible.
