What is the primary purpose of an initramfs?

To provide a user interface for boot options.

To store the kernel image itself.

To store system logs from the boot process.

To provide a minimal root filesystem and drivers needed to mount the real root filesystem.

A developer is building a custom kernel and needs to understand the meaning of a specific configuration option (CONFIG_IKCONFIG). Where should they look for authoritative documentation?

The bootloader configuration file

The man page for the kernel module

The kernel source tree's Documentation directory, specifically /usr/src/linux/Documentation/

During boot, what is the typical order of loading?

Bootloader loads the kernel, then the initramfs, then the kernel mounts the real root.

The real root is mounted before the initramfs is loaded.

The kernel loads the initramfs, then the bootloader, then the real root.

The initramfs loads the kernel, then the bootloader.

An administrator compiled and installed a new kernel. The system boots, but the new kernel cannot find the root filesystem. The root filesystem is on a SCSI disk. The SCSI driver is built as a module. What is the most likely cause?

The bootloader is not passing the correct root device.

The initramfs does not include the SCSI driver module.

The kernel modules were not installed.

The kernel was not configured with SCSI support.

A module fails to load with 'Operation not permitted'. The administrator checks dmesg and sees 'module verification failed: signature and/or required key missing'. The system uses Secure Boot. What is the most appropriate action?

Recompile the module with a different compiler.

Disable Secure Boot in the BIOS.

Sign the module with a key trusted by the system's Secure Boot configuration.

Use insmod instead of modprobe to bypass the check.

201.1 Kernel Components (weight: 2) LPIC-2 Practice Questions (Page 2)

Part of the Topic 201: Linux Kernel domain, which makes up ~9% of our current practice bank. Linux Professional Institute does not publish an official question count, but from its 90-minute exam (~35–60 total, ~3–5 in this domain), expect 1–2 from this objective — we provide 36 practice questions to prepare you well beyond it.
