010-100 Question #76: Real Exam Question with Answer & Explanation

The correct answer is B. Virtualization lets you run several operating systems on the same hardware in parallel. E. Virtualization allows separation of services, tasks and users in distinct virtual machines.. Virtualization allows multiple operating systems to run concurrently on shared hardware and enables workload isolation through virtual machines. It is supported on Linux and is heavily used in server environments.

Question

Which statements are true about virtualization? (Choose TWO answers)

Options

AVirtualization is not supported by Linux because of its permissions and multi-user requirements.
BVirtualization lets you run several operating systems on the same hardware in parallel.
CVirtualization is a proprietary technology that has additional licence costs even for Linux.
DVirtualization is a pure desktop technology that should not be used on servers.
EVirtualization allows separation of services, tasks and users in distinct virtual machines.

Explanation

Virtualization allows multiple operating systems to run concurrently on shared hardware and enables workload isolation through virtual machines. It is supported on Linux and is heavily used in server environments.

Common mistakes.

A. Linux has robust virtualization support, including KVM (Kernel-based Virtual Machine) built directly into the kernel; its multi-user and permissions model does not prevent virtualization.
C. Virtualization is not proprietary technology requiring additional licensing for Linux; open-source hypervisors like KVM, Xen, and QEMU are freely available and widely used.
D. Virtualization is extensively used in server and data center environments, not only on desktops; server virtualization is in fact one of its primary and most common use cases.
