Distinguishing the VM guest kernel | LinuC Level 1 101 Exam original practice question

1.01.2Basic

Start a Linux guest VM on a Linux host.

Which statement about the guest OS kernel is correct?

Hint 1: Focus on the requirement

Identify whether the statement describes a full guest operating system or a process-level isolation mechanism.

Hint 2: Key terms

Review the short definitions before comparing the virtualization or lifecycle choices.

Guest kernel: The kernel booted by a guest operating system inside a virtual machine.
Virtual CPU: A processor interface that the hypervisor exposes to a guest.
VM isolation: A boundary in which a guest has its own virtual hardware and operating-system state.

Detailed explanation

Incorrectホストの全プロセスと同じPID名前空間だけを使う

Incorrect. Sharing a PID namespace describes a container model, not a normal VM.

Incorrectゲストにはカーネルが存在しない

Incorrect. A VM has a guest kernel.

Correctゲストは自身のカーネルを仮想CPU上で実行する

Correct. The guest runs its own kernel on virtual CPU resources.

Incorrectホストのカーネルファイルを必ず直接上書きする

Incorrect. A guest does not overwrite the host kernel file as part of normal boot.

An example you can run in a temporary verification environment.

uname -r

現在実行中の環境のkernel release

Foundation review

A virtual machine can use a different kernel from its host, while a normal container uses the host kernel.

Use the guest's own uname output or console when verifying its kernel; the host's process view is a different context.
