Which of the following does not belong to the mode that Linux will increase after installing the KVI module?

Question

Options

• AClient mode
• BUser Mode
• CInterrupt mode
• DKernel mode

• A
  3% (1)
• B
  3% (1)
• C
  84% (32)
• D
  11% (4)

Explanation

Interrupt mode (C) is the answer that does not belong because KVM (Kernel-based Virtual Machine) introduces exactly three processor privilege levels: Guest mode, User mode, and Kernel mode - "interrupt mode" is not a mode added by KVM; interrupt handling occurs within existing kernel-mode execution, not as a separate KVM-defined mode.

Why the distractors are wrong:

• A (Client/Guest mode) - KVM does add Guest mode (sometimes called "client mode" in translated materials), where the virtual machine's OS code executes.
• B (User mode) - KVM does use User mode, where the QEMU userspace process manages the VM from outside the kernel.
• D (Kernel mode) - KVM does extend Kernel mode, where the KVM kernel module performs hypervisor-level operations.

Memory tip: Think of KVM's three modes as matching its full name - Kernel mode, a Virtualized guest (Client) mode, and User mode (KVU). "Interrupt" is a CPU mechanism, not a mode, so it's the outlier.
