A Virtual Machine includes which of the following components?

• A. CPU, Memory (RAM), Network Interface Card (vNIC), and Storage (Virtual Disk)
• B. CPU Only
• C. Memory Only
• D. Storage Only

Answer: (A)

A virtual machine provides a complete, software-defined computer to a guest operating system, exposing the same kinds of resources a real machine would. The essential building blocks are a processor to execute instructions, memory to hold data and programs in use, a network interface to connect to other machines, and storage to keep the operating system, applications, and data persistently. The hypervisor sits underneath and allocates these virtual resources from the physical hardware, presenting virtual devices to the VM. Because all four components are exposed, the guest OS can boot, run applications, access network resources, and read/write data to disk as if it were on a real machine. If any one of these were missing—no memory, no vNIC, or no virtual disk—the VM wouldn’t be able to operate or persist data, which is why including all of them is the correct description.
