LPIC-3 Exam 305 (Virtualization and Containerization) — Question 8

Which of the following are true regarding the CPU of a QEMU virtual machine? (Choose two.)

Answer options

• A. The CPU architecture of a QEMU virtual machine is independent of the host system’s architecture.
• B. Each QEMU virtual machine can only have one CPU with one core.
• C. For each QEMU virtual machine, one dedicated physical CPU core must be reserved.
• D. QEMU uses the concept of virtual CPUs to map the virtual machines to physical CPUs.
• E. QEMU virtual machines support multiple virtual CPUs in order to run SMP systems.

Correct answer: A, E

Explanation

Option A is correct because QEMU allows the emulation of different CPU architectures regardless of the host system. Option E is also correct, as QEMU supports multiple virtual CPUs, enabling it to run symmetric multiprocessing (SMP) systems. Options B, C, and D are incorrect; B and C limit the capabilities of QEMU virtual machines, and D misrepresents the function of virtual CPUs in QEMU.
