LPIC-1 Exam 101 v5 (Linux Administrator) — Question 18

Which of the following statements are correct about the initial RAM disk involved in the boot process of Linux? (Choose two.)

Answer options

• A. An initramfs is a compressed file system archive, which can be unpacked to examine its contents.
• B. An initramfs file contains the MBR, the bootloader and the Linux kernel.
• C. After a successful boot, the initramfs contents are available in /run/initramfs/.
• D. The kernel uses the initramfs temporarily before accessing the real root file system.
• E. An initramfs does not depend on a specific kernel version and is not changed after the initial installation.

Correct answer: A, D

Explanation

Option A is correct because an initramfs is indeed a compressed filesystem that can be unpacked to view its contents. Option D is also correct as the kernel does use the initramfs temporarily during the boot process. Options B, C, and E are incorrect; B is wrong because an initramfs does not contain the MBR or bootloader, C is incorrect since the initramfs contents are not available at /run/initramfs/ after boot, and E is false because the initramfs can be tied to specific kernel versions.
