Separating /boot from an encrypted root | LinuC Level 1 101 Exam original practice question

1.04.4Basic

Place the root filesystem on encrypted LVM.

Ensure the bootloader can reach the kernel and initramfs before the complex root environment is available.

Which design is generally useful?

Hint 1: Focus on the requirement

Identify what must change and what must remain unchanged. Then choose the command whose scope matches that requirement.

Hint 2: Check each command's role

Separate commands that display information, change state, remove data, or affect a child process.

rpm -ql /bin/bash: Incorrect. A separate /var helps variable data capacity but does not directly make boot files reachable.
rpm -qf /bin/bash: Correct. A readable /boot can hold initial boot files outside the encrypted root.
rpm -qR /bin/bash: Incorrect. A separate /home isolates user data rather than boot files.
rpm -K /bin/bash: Incorrect. Swap cannot substitute for an ESP or /boot.

Foundation review

Check whether the command acts on the current shell, a new process, an existing process, or a file.
