Where is a virtual switch typically located?

• A. As a software anti-virus program.
• B. As a standalone physical switch in the data center.
• C. As a logical component within a virtualized server platform, such as a hypervisor driver or plug-in.
• D. As a cloud backup service.

Answer: (C)

A virtual switch is a software-based network component that runs inside the host’s virtualization layer. It provides the data path between virtual machines on the same host and connects them to physical networks through the host’s NICs. Because it operates as part of the virtualization platform, it’s a logical component within the virtualized server environment, typically implemented as a driver or plug-in inside the hypervisor (for example, VMware vSwitch, Hyper-V virtual switch, or Open vSwitch). It is not an antivirus program, not a standalone physical switch, and not a cloud backup service.
