The Network File System (NFS) described in Section 4.5 allows a client machine to run operations on files that are stored at a remote server. For the version of NFS described there, decide if each of these assertions is true or false:

A. When the server responds to a client’s write call, all modifications required by that write will have made it to the server’s disk.

B. An NFS client might send multiple requests for the same operation to the NFS server.

C. When an NFS server crashes, after the operating system restarts and recovers the disk contents, the server must also run its own recovery procedure to make its state consistent with that of its clients.
