Network Administrator Commands on Layer 3 Switch

What is the administrator configuring?

A network administrator issues the following commands on a Layer 3 switch:

DLS1(config)# interface f0/3

DLS1(config-if)#no switchport

DLS1(config-if)#ip address 172.16.0.1 255.255.255.0

Choose the correct option:

A. a Cisco Express Forwarding instance

B. a routed port

C. a trunk interface

D. a switched virtual interface

Answer:

The network administrator is configuring a routed port. Option B is correct.

The "no switchport" command is used to change the Layer 2 switch port to a Layer 3 routed port. Then, the "ip address" command assigns an IP address to the port, and "no shutdown" command brings the interface up. Finally, "end" command exits the interface configuration mode.

A routed port is a Layer 3 interface that is used to route traffic between different networks or subnets, and it is associated with a single VLAN. In this case, the network administrator is configuring a Layer 3 interface with an IP address, which can be used to route traffic between different subnets.

Therefore, option B is correct.
