Which two statements describe a routed switch port on a multilayer switch? (Choose two.)
A.
Layer 2 switching and Layer 3 routing are mutually supported.
B.
The port is not associated with any VLAN.
C.
The routed switch port supports VLAN subinterfaces.
D.
The routed switch port is used when a switch has only one port per VLAN or subnet.
E.
The routed switch port ensures that STP remains in the forwarding state.
Explanation:
A routed port is a physical port that acts like a port on a router; it does not have to be connected to
a router. A routed port is not associated with a particular VLAN, as is an access port. A routed port
behaves like a regular router interface, except that it does not support VLAN subinterfaces.
Routed ports can be configured with a Layer 3 routing protocol. A routed port is a Layer 3 interface
only and does not support Layer 2 protocols, such as DTP and STP. You can configure routed
ports by putting the interface into Layer 3 mode with the no switchport interface configuration
command. Then you have to assign an IP address to the port, enable routing, and assign routing
protocol characteristics by using the ip routing and router protocol global configuration commands.
