There are three levels in the computing virtualization architecture, which of the following does not belong to the three levels of the host?

Question

Options

• Ahypervisor
• BDockerwning
• CGuest Machine
• DHost machino

• A
  5% (1)
• B
  77% (17)
• C
  14% (3)
• D
  5% (1)

Explanation

Option B ("Dockerwning") is correct because it is not a recognized term or component in the three-level computing virtualization architecture - it appears to be a fabricated or misspelled option with no meaning in virtualization theory.

The three legitimate levels are: the Host Machine (D), which is the physical hardware running the system; the Hypervisor (A), the software layer that creates and manages virtual machines by abstracting hardware resources; and the Guest Machine (C), the virtual OS instance running on top of the hypervisor. Each of A, C, and D represents a real, distinct tier in the standard virtualization stack.

Memory tip: Think of the three levels as a sandwich - the Host is the bottom slice (physical hardware), the Hypervisor is the filling (the management layer in between), and the Guest is the top slice (the virtual machine the user interacts with). Any option that doesn't fit into this hardware → virtualization → virtual OS hierarchy is the odd one out.
