Which two are true of an NFS repository when used with Oracle VM?
A. NFS repositories are excellent for storing guests’ root file systems.
B. NFS is a more expensive option than iSCSI or SAN fabrics.
C. OCFS2 must be used as the filesystem format for volumes exposed through NFS.
D. NFS shares mounted directly in a guest require the DM-NFS driver to be installed on the guest.
E. NFS is supported for use in RAC only when mounted from the guest (not domO).

Explanation/Reference:
Explanation:
First of all here you have to select two options but answer shows one. A is ok.
