Which of the following statements are true regarding emulation? (Choose TWO)

Question

Options

• AEmulation allows operating systems to be run on foreign architectures
• BEmulation can only provide distinct hardware components but no complete virtual machines
• CEmulation implements a whole computing system in software
• DEmulation requires changes to the guest operating system

• A
  78% (32)
• B
  7% (3)
• D
  15% (6)

Explanation

Emulation is a technique in which a complete computing system is implemented entirely in software. According to virtualization documentation, emulation allows operating systems and applications compiled for one CPU architecture to run on a different, foreign architecture, making statement A correct. Statement C is also correct because emulation reproduces the entire hardware environment, including CPU, memory, and devices, using software alone. This contrasts with virtualization, which relies on hardware support and does not emulate the full system. Statement B is incorrect because emulation does provide full virtual machines, not just individual components. Statement D is also incorrect, as emulation does not require changes to the guest OS; the guest believes it is running on real hardware.
