Exhibit

# mount | grep sda1
/dev/sda1 on /boot type xfs (rw,relatime,seclabel,attr2,inode64,noquota)
# cat /etc/fstab
/dev/mapper/rhel-root /                       xfs     defaults        0 0
UUID=12345678-1234-1234-1234-123456789abc /boot                   xfs     defaults        0 0
/dev/mapper/rhel-swap swap                    swap    defaults        0 0
# blkid /dev/sda1
/dev/sda1: UUID="12345678-1234-1234-1234-123456789abc" TYPE="xfs"

Answer choices

Why each option matters

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.

    Related concept

    Read the scenario before looking for a memorised answer.

  • 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.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.
