Which two statements describe a routed switch port on a multilayer switch? (Choose two.)

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.
