QUESTION 35

Why will a switch never learn a broadcast address?

A. Broadcast frames are never sent to swiches.

B. Broadcast addresses use an incorrect format for the switching table.

C. A broadcast address will never be the source address of a frame.

D. Broadcasts only use network layer addressing.

E. A broadcast frame is never forwarded by a switch.

Correct Answer: C

Section: Switching

Explanation

Explanation/Reference:

Switches only put source MAC addresses into their switching table: they want to know from which direction a frame came from, so they can send frames back in

that direction as required. The broadcast address is never the source address, so switches will never put the broadcast address into their switching tables.
