A system administrator wants to share NFS file systems to two different sets of systems. Both sets of systems require integrity checks and Kerberos authentication. The second set of systems also requires encryption. What option is open to the system administrator?

A.
Use an NFS server in two different zones, sharing the same data.

B.
Share the same file system with different sec options for both sets of clients.

C.
Share the file system only with NFSv4, because older NFS versions do not support this.

D.
Logically divide the file system into two separate file systems, each shared with different sec options.
