LPIC-2 Network Client Management Practice Question
This LPIC-2 practice question tests your understanding of network client management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrator needs to mount an NFSv4 export from server:/exports/data onto /mnt/data on a client. The requirement is to use Kerberos security, a hard mount, and ensure that the NFS server does not squash root's privileges. Which line in /etc/fstab correctly implements these requirements?
Option D is correct because it specifies NFSv4 with Kerberos security (sec=krb5) and a hard mount, which meets the requirements. The no_root_squash option is not a valid mount option in /etc/fstab for the client side; it is an export option set on the NFS server in /etc/exports. Thus, D correctly omits it, as the client cannot enforce root squashing behavior.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
Correctly uses sec=krb5 and hard; no_root_squash is configured on the server.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates mistakenly include no_root_squash as a client-side mount option in /etc/fstab, confusing it with a server-side export option, or they choose a soft mount instead of hard.
Detailed technical explanation
How to think about this question
In NFSv4 with Kerberos (sec=krb5), the client and server use RPCSEC_GSS for authentication, integrity, and optionally encryption. The hard mount option causes the client to retry indefinitely on server failure, preventing data corruption from interrupted I/O, while soft returns errors after a timeout. Root squashing is controlled server-side via the root_squash or no_root_squash export option in /etc/exports, not in the client's fstab.

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A junior network technician can log in to a core router but cannot reach the enable prompt or configuration mode. The AAA server is authenticating the login — but the authorisation policy only grants privilege level 1, not 15. Authentication (who you are) is working; authorisation (what you can do) is not.

What is the correct answer to this question?
The correct answer is: server:/exports/data /mnt/data nfs4 defaults,sec=krb5,hard 0 0 — Option D is correct because it specifies NFSv4 with Kerberos security (sec=krb5) and a hard mount, which meets the requirements. The no_root_squash option is not a valid mount option in /etc/fstab for the client side; it is an export option set on the NFS server in /etc/exports. Thus, D correctly omits it, as the client cannot enforce root squashing behavior.
