EX200 Create and configure file systems Practice Question
This EX200 practice question tests your understanding of create and configure file systems. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 is configuring an NFS mount in /etc/fstab to mount from server:/export to /mnt/data. The mount must use the 'hard' and 'nosuid' options. Which line is correct?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
server:/export /mnt/data nfs nosuid,hard 0 0
Option E is correct because it specifies the NFS filesystem type and includes both required mount options: 'nosuid' (disallows set-user-identifier/set-group-identifier bits) and 'hard' (retries NFS requests indefinitely until the server responds). The syntax follows the correct /etc/fstab format: <server>:/<export> <mountpoint> <fstype> <options> <dump> <pass>.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Red Hat often tests the misconception that 'defaults' can be combined with other options without conflict, but in reality 'defaults' includes 'suid', which directly contradicts the required 'nosuid' option.
Detailed technical explanation
How to think about this question
The 'hard' mount option causes NFS operations to retry indefinitely until the server responds, which is critical for data integrity in production environments (unlike 'soft', which returns errors after a timeout). The 'nosuid' option ignores setuid/setgid bits on the mounted filesystem, a security measure to prevent privilege escalation from untrusted NFS exports. In /etc/fstab, the order of options does not matter, but 'defaults' should not be mixed with explicit options because it expands to 'rw,suid,dev,exec,auto,nouser,async' and can override explicit flags.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
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 practitioner preparing for the EX200 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
