• True

• False

Many of the concepts used in today's virtualization products date back to IBM mainframe computers for the 1970s.

• True

• False

The hypervisor intercepts and processes requests coming from the guest operating systems and then returns the results back to the virtual machine.

• True

• False

A virtual machine can't share the use of a network adapter with the host.

• True

• False

Cloud services are highly reliant upon the use of virtualization technology.

• True

• False

What component of virtualization controls all physical memory, and thus has the ability to make any unused memory pages in each guest available for other virtual machines or the host computer?

• The guest operating system

• The host operating system

• The hypervisor

• The BIOS

What virtualization technology makes it possible to avoid overhead associated with software-managed shadow page tables?

• Time Sliced Prioritization Method (TSPM)

• Second Level Address Translation (SLAT)

• Threaded Input / Output Translation (TIOT)

• Virtual Disk Interface Layer (VDIL)

Which of the following does an operating system installed in a guest virtual machine do?

• interacts directly with host machine hardware

• controls the hypervisor

• interacts with hardware through the hypervisor

• intercepts requests for an emulated hard drive

What hypervisor uses a special guest called Domain 0 that loads along with the hypervisor and is used to directly access the hardware?

• VMWare ESXi

• VMWare Workstation

• Oracle VirtualBox
