When a Layer 3 device receives a frame, what is the first thing it does?
remove the frame header
remove the packet header
read the IP addresses in the frame header
read the IP addresses in the packet header
Once a Layer 3 device determines the route to a destination, what does it do before sending the traffic toward its ultimate destination?
Add a new frame header to forward the traffic to the next Layer 3 device in the route or its final destination on the internal network.
Change the destination IP address.

Where are routers normally located in a network architecture hierarchy?
At the bottom of the hierarchy
In between the endpoint devices and the switches
At the top of the hierarchy

A multilayer switch is capable of which of the following? Select all that apply.
routing
switching
data segmentation
data reassembly
A Layer 3 switch is used at all of the following layers in a hierarchical switch backbone except
core
distribution
access
Layer 3 switches are used at all 3 layers; that's why they're called Layer 3 switches.

WLC
All options are used to centralize control of a wireless LAN
Layer 3 roaming on a WLC
allows the WLC to process traffic at Layer 3 as well as Layer 3.
allows wireless clients to move between wireless APs without losing network connectivity.
allows the WLC to communicate with all the network's wireless APs over Layer 3.
