CV0-003 · Question #118

Which of the following virtual network components allows a virtual NIC to connect to local area resources?

The correct answer is B. Virtual switch. A virtual switch (vSwitch) is the core virtual networking component that connects virtual NICs to the physical network, enabling VMs to reach local area network resources.

Why each option

A virtual switch (vSwitch) is the core virtual networking component that connects virtual NICs to the physical network, enabling VMs to reach local area network resources.

Avirtual router

A virtual router operates at layer 3 to route traffic between different IP networks or subnets, not to provide basic LAN connectivity for a virtual NIC.

BVirtual switchCorrect

A virtual switch operates like a physical layer-2 switch inside a hypervisor, connecting virtual NICs of VMs to each other and to uplink ports tied to physical NICs. This allows VMs to communicate with resources on the local area network just as a physical NIC connected to a physical switch would. Without a virtual switch, virtual NICs would have no path to the LAN.

CVirtual network

A virtual network is a broad architectural concept encompassing multiple components rather than a specific device that directly connects a vNIC to LAN resources.

DVirtual gateway

A virtual gateway provides egress from one network segment to another (often to external or different subnets) and is not the component that bridges a vNIC to local LAN resources.
