Actual exam question for LPI's 201-450 exam

Question #: 90
Topic #: 1

In case the file containing the Linux kernel is lost, what happens when the system is booting?

AThe system starts normally since the bootloader copies the kernel to the master boot record of the hard disk.

BInstead of the kernel, the initramfs is loaded and instructed to mount the root filesystem and reinstall the kernel from the original package or from source.

CThe bootloader mounts the root filesystem read-only and launches /bin/sh directly in order to allow the administrator to reinstall the kernel.

DWithout a kernel a system cannot boot and, depending on the bootloader, an error is displayed.

Ah, the classic kernel conundrum. I'd have to go with D on this one. No kernel, no boot. Simple as that. Though I have to say, the thought of the bootloader trying to reinstall the kernel on its own is pretty amusing.

I agree, without the kernel the system can't boot.

Haha, option C is just silly. The bootloader can't magically mount the root filesystem and launch a shell without a kernel! That's like trying to drive a car without an engine.

User1: Option C does sound unrealistic. How can a system run without a kernel?

I'm going with option B. The initramfs should be able to mount the root filesystem and reinstall the kernel from the original package or source.

Yes, having the initramfs load and reinstall the kernel is a good fail-safe measure.

I agree, it's important to have a backup plan in case the kernel file is lost.

I think option B is the best choice. The initramfs can help reinstall the kernel.

I think option D is the correct answer. Without a kernel, the system cannot boot. The bootloader will just display an error message indicating that the kernel is missing.

I agree with Carolann, because without the kernel, the system cannot boot and initramfs is used to load the root filesystem.

I believe the correct answer is B) Instead of the kernel, the initramfs is loaded and instructed to mount the root filesystem and reinstall the kernel.

I think if the Linux kernel file is lost, the system won't boot properly.
