B. Establish a direct link from the switch to all other switches in the network
C. Configure the switch full-duplex operation and configure the other switches for
half-duplex operation
D. Configure the switch so that it has lower priority than other switches in the network
E. None of the above
Answer: D

Switch having lowest bridge ID will become the root bridge. The bridge ID is how STP
keeps track of all the switches in the network. It is determined by a combination of the
bridge priority (32,768 by default on all Cisco switches) and the base MAC address. The
bridge with the lowest bridge ID becomes the root bridge in the network. To elect the
desired switch as a root bridge, set the bridge priority lowest than other switch.

address?
A. Broadcast frames are never sent to switches
B. A broadcast frame is never forwarded by a switch
C. Broadcasts only use network layer addressing
D. A broadcast address will never be the source address of a frame
E. Broadcast addresses use an incorrect format for the switching table
F. None of the above
Answer: D
Explanation:
There are three different address types:
* Unicast : One source to One destination
* Broadcast: One source to multiple destination
* Multicast: One source to multiple destination joined to group
On unicast or broadcast or multicast communication, the source address is always the
unicast address but the destination address can be unicast, broadcast or multicast.
