      Question

      In the context of virtualization, paravirtualization

      differs from full virtualization in which of the following ways? 
      A Paravirtualization requires hardware support for virtualization. Correct Answer Incorrect Answer
      B Paravirtualization modifies the guest operating system to work with the hypervisor. Correct Answer Incorrect Answer
      C Full virtualization is slower than paravirtualization due to the need for translation. Correct Answer Incorrect Answer
      D Paravirtualization can only be used with Linux-based operating systems. Correct Answer Incorrect Answer
      E Full virtualization provides direct access to the host’s hardware. Correct Answer Incorrect Answer

      Solution

      Paravirtualization requires modifications to the guest operating system to allow it to interact more efficiently with the hypervisor. This allows the guest OS to perform virtualization-aware operations, reducing the overhead associated with traditional full virtualization, where the hypervisor must emulate the hardware for the guest OS. Option A is incorrect because paravirtualization does not necessarily require hardware support, unlike full virtualization, which often benefits from hardware-assisted virtualization. Option C is wrong because while full virtualization may introduce some overhead due to instruction translation, paravirtualization gains performance by avoiding this overhead through OS modification. Option D is incorrect as paravirtualization is not limited to Linux; it can work with various OSs as long as they support necessary modifications. Option E is incorrect because full virtualization does not provide direct hardware access; instead, it emulates the hardware environment for guest OSes.
