Switches perform three actions when making a switching decision. (Choose 3)

a. Decide whether or not to forward the frame based on the destination MAC address.
b. Preparing to forward packets by learning the IP address by examining the source IP address of each packet received by the switch.

b. No speed 100

Both ends of a connection between two switches must use the same speed. a. True b. False

a. True

What happens if auto-negotiation for port speed is disabled between two ports? a. The switch, being Cisco, will try to sense the speed and set appropriately. However, if this fails, fail back to IEEE defaults of 10 Mbps. b. The switch, being Cisco, will not try to sense the speed and automatically default to 10 Mbps. c. The switch, being Cisco, will try to sense the speed but only negotiate the highest possible rate, otherwise the link fails. d. The switch, being Cisco, will set to 10 Mbps and half-duplex.

a. The switch, being Cisco, will try to sense the speed and set appropriately. However, if this fails, fail back to IEEE defaults of 10 Mbps.

A port security violation has occurred if: a. A switchport discovers a new MAC address on the port. b. A switchport adds a MAC address to the switchport. c. A switchport learns a new source MAC address and it has exceeded the maximum configured. d. None of the above.
