Question 23

An engineer is deploying a client-side virtualization workstation. What resource requirements should the engineer consider? (Select all that apply.)

Answer 23

CPU and virtualization extensions

Networking

Most virtualization software requires a central processing unit (CPU) with virtualization support enabled. Even if there is no formal requirement, the VMs will be impaired if hardware-assisted virtualization is unavailable.

A hypervisor will create a virtual network environment through which all the virtual machines (VMs) can communicate and has a network shared by the host and by VMs on the same host and other hosts.

Question 24
