    • executing programs in containers
    • running programs directly on computer hardware
  2. a hypervisor allows:​​ (choose two)

    • virtual resources to be accessed by operating systems and application software
    • an operating system to be installed on virtual hardware
    • application software to run without an operating system
    • system calls to be directly executed by physical hardware

    • True
    • False
  4. Hosted hypervisor systems require:

    • dedicated datacenter resources
    • a host operating system
