LFCS Storage Management Practice Question
Which THREE of the following are valid methods to mount an NFS filesystem on a client?
⚠ Common exam trap
It's easy for candidates to confuse NFS with CIFS/SMB (option C) or forget that `mount -t nfs4` is a valid alternative to `mount -t nfs` for NFSv4 exports, while option A is a valid configuration method but not a direct mount command as the question implies.

Correct answer & explanation
✓
mount -o hard,intr server:/export /mnt
The `mount` command with `-o hard,intr` specifies NFS-specific mount options: `hard` ensures that NFS operations retry indefinitely until the server responds, and `intr` allows signals to interrupt a hung NFS operation. The command `mount -o hard,intr server:/export /mnt` uses the default NFS version (typically NFSv3) and is a valid method to mount an NFS filesystem on a client.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
echo 'server:/export /mnt nfs defaults 0 0' >> /etc/fstab && mount -a
Why it's wrong here
While mount -a is a valid method to mount filesystems from /etc/fstab, the given command involves two steps: adding an entry to fstab and then running mount -a. The question asks for direct mount commands that mount an NFS filesystem immediately without prior configuration. Additionally, the fstab entry uses 'defaults' which may not include necessary NFS options like 'hard' or 'intr' for proper operation. Therefore, option A is not considered a valid single-step mount method.
- ✓
mount -o hard,intr server:/export /mnt
Why this is correct
Correct: NFS mount with options.
- ✗
mount -t cifs server:/share /mnt
Why it's wrong here
Incorrect: -t cifs is for CIFS, not NFS.
- ✓
mount -t nfs server:/export /mnt
Why this is correct
Correct: Explicit NFS type.
- ✓
mount -t nfs4 server:/export /mnt
Why this is correct
Correct: NFSv4 type.
