Question 20/20
Explanation: If you want to provide NFS service to other hosts, you have to run the rpc.nfsd and rpc.mountd
daemons on your machine. As RPC-based programs, they are not managed by inetd, but are started up at boot
time and register themselves with the portmapper; therefore, you have to make sure to start them only after
rpc.portmap is running. Port map provides port information to clients requesting RPC services on the server.
Mountd determines
which file system and devices are available to which machine and users. Nfsd is the daemon on the server that
handles client file system requests.

Incorrect Answers
B: Nfsiod runs on an NFS client machine to service asynchronous I/O requests to its server. It improves
performance but is not required for correct operation.
D: Xinetd is a replacement for inetd, the internet services daemon, and offers improved functionality. However,
it is not a requirement to run NFS.
