VIRTUALIZATION

1) What is virtualization?

• a) A process to reduce software costs
  

• b) A technique to run multiple operating systems on a single physical machine
  

• c) A type of cloud storage
  

• d) A method for data encryption

Which of the following is NOT a type of virtualization?

• a) Network virtualization
  

• b) Storage virtualization
  

• c) Application virtualization
  

• d) Hardware fragmentation

3) Which component manages virtual machines in a virtualization environment?

• a) Hypervisor
  

• b) Kernel
  

• c) BIOS
  

• d) Compiler

4) Which of the following is a benefit of virtualization?

• a) Increased hardware costs
  

• b) Reduced flexibility
  

• c) Improved resource utilization
  

• d) Limited scalability

5) In which type of virtualization do virtual machines run directly on hardware without the need for a host operating system?

• a) Type 1 Hypervisor
  

• b) Type 2 Hypervisor
  

• c) Full Virtualization
  

• d) Desktop Virtualization

6) In which type of virtualization is the guest operating system modified to work in a virtual environment?

• a) Full Virtualization
  

• b) Para-virtualization
  

• c) Storage Virtualization
  

• d) Network Virtualization

Which of the following is a disadvantage of para-virtualization?

• a) It requires more hardware resources
  

• b) It cannot run unmodified operating systems
  

• c) It leads to increased virtualization overhead
  

• d) It lacks scalability compared to full virtualization

8) Which of the following best describes full virtualization?

• a) The hypervisor presents a complete simulation of the underlying hardware
  

• b) The guest OS has direct access to physical hardware
  

• c) The hypervisor requires extensive modifications to the host OS
  

• d) The guest OS uses shared kernel modules for performance

9) What is the key difference between full virtualization and para-virtualization?

• a) Full virtualization provides better performance than para-virtualization
  

• b) Para-virtualization requires guest OS modification, while full virtualization does not
  

• c) Full virtualization runs only on specialized hardware
  

• d) Para-virtualization does not use a hypervisor

10) Para-virtualization typically offers better performance than full virtualization because:

• a) It reduces the number of layers between the guest OS and hardware
  

• b) It eliminates the need for a hypervisor
  

• c) It uses dedicated hardware components
  

• d) It runs unmodified guest operating systems
