Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Edit /etc/fstab to add 'noexec' to the /boot entry, then run mount -o remount /boot
To add 'noexec' permanently, edit /etc/fstab and add 'noexec' to the options field of the /boot entry (e.g., defaults,noexec). Then remount with 'mount -o remount /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 -o remount,noexec /boot without editing /etc/fstab
Why it's wrong here
Incorrect. This remounts with noexec but the change is not permanent.
✓
Edit /etc/fstab to add 'noexec' to the /boot entry, then run mount -o remount /boot
Why this is correct
Correct. This makes the change permanent and applies it.

✗
Run umount /boot, edit /etc/fstab to add 'noexec', then mount /boot
Why it's wrong here
Incorrect. umount may fail if /boot is in use; remount is safer.
✗
Edit /etc/fstab to add 'noexec' to the /boot entry, then run mount -a
Why it's wrong here
Incorrect. mount -a mounts all filesystems from fstab but does not remount already mounted filesystems.

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.
