A. Forwards the switch to the first available link B. Drops the frame c. Floods the network with the frame looking for the device D. Sends back a message to the originating station asking for a name resolution

11. If a switch receives a frame and the source MAC address is not in the MAC address table but the destination addressis, what will the switch do with the frame? A. Discard it and send an error messageback to the originating host B. Flood the network with the frame C. Add the source address and port to the MAC address table and forward the {rame out the destination port D. Add the destination to the MAC address table and then forward the frame 12. You want to run the new 802. lw on your switches. Which of the following would enabie this protocolf A . S w i t c h ( c o n f i g ) # s p a n n i n g - t r em o d er a p i d - p v s t e B .
