What is a hypervisor? A. is a software program that manages multiple operating systems (or multiple instances of the same operating system) on a single computer system. B. It is the position after supervisor C. is a firmware that allows encrypted file systems D. Is a thin layer of software than runs inside the virtual machines

A. is a software program that manages multiple operating systems (or multiple instances of the same operating system) on a single computer system.

What is a blue pill attack? A. An attack in which one virtual machine freeze B. An attack in which a rootkit is installed that can intercept all the calls to the hypervisor and redirect them, unbeknownst to the operating system. C. An attack that turn the screen blue D. A highly developed code that puts a smurf clocking applications.

B. An attack in which a rootkit is installed that can intercept all the calls to the hypervisor and redirect them, unbeknownst to the operating system.
