第10题:
The port must be physically connected to another Layer 3 device.
At least one port in VLAN 20 must be active.
The Layer 3 routing protocol must be operational and receiving routing updates from neighboring peer devices.
Because this is a virtual interface, the operational status will always be in an up/up state.
