- A.
Server and client daemons are started at run-level 2
- B.
Server and client daemons are started at run-level 3
- C.

- D.
Server daemons are started at run-level 2, client daemons at run-level 3
Correct Answer
C. Server daemons are started at run-level 3, client daemons at run-level 2Explanation
The correct answer is that server daemons are started at run-level 3, while client daemons are started at run-level 2. This means that the server daemons, which handle the file system sharing, are started at a higher run-level than the client daemons, which are responsible for accessing and using the shared file systems. This setup ensures that the server daemons are up and running before the client daemons start, allowing for a smooth and efficient NFS operation.Rate this question:
