An NFS server exports a directory to a client with the option `rw,no_root_squash`. A security audit flags this as a risk. The administrator wants to maintain read-write access for regular users but eliminate the root privilege escalation risk. Which change should be made?

Remove the client from the export list.

Change `no_root_squash` to `root_squash`.

A client mounts an NFS share, but the files appear to be owned by `nobody` instead of the expected user. The server and client have the same user database. What is the most likely cause?

The server has `root_squash` enabled.

The client is using a different NFS version than the server.

The client is mounting with the `sec=sys` option.

The export uses `all_squash`, mapping all users to the anonymous UID.
