EX200 Deploy, configure, and maintain systems Practice Question
This EX200 practice question tests your understanding of deploy, configure, and maintain systems. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Which THREE of the following are common steps to configure a system to automatically mount an NFS share at boot?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ensure nfs-utils is installed
B is correct because the NFS client functionality in Red Hat Enterprise Linux is provided by the nfs-utils package. Without this package installed, the system lacks the necessary tools (such as mount.nfs and rpcbind) to mount NFS shares, making it impossible to configure automatic mounting at boot.
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.
✗
Run 'mount -a' after boot
Why it's wrong here
This command mounts all fstab entries but is not a configuration step for boot.
✓
Ensure nfs-utils is installed
Why this is correct
The nfs-utils package provides necessary utilities for NFS client.

✓
Use autofs
Why this is correct
autofs provides on-demand mounting and can be configured to start at boot.

✗
Configure /etc/exports
Why it's wrong here
/etc/exports is used on the NFS server to export directories, not on the client.
✓
Add an entry to /etc/fstab
Why this is correct
Adding an entry to /etc/fstab is the traditional method to mount at boot.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Red Hat often tests the misconception that /etc/exports is a client-side configuration file, when in fact it is strictly a server-side file used to define exported directories, not client-side automount settings.
Trap categories for this question
Command / output trap
This command mounts all fstab entries but is not a configuration step for boot.
Detailed technical explanation
How to think about this question
The NFS client uses the rpcbind service and the NFSv3 or NFSv4 protocol to communicate with the server. When adding an entry to /etc/fstab for an NFS share, the systemd automount unit relies on the nfs-client.target to start the necessary services (such as rpc-statd and nfs-idmapd) before attempting the mount. In a real-world scenario, if nfs-utils is missing, the fstab entry will fail silently at boot, and the system may hang waiting for the mount to complete.
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.
