In the network shown in the following graphic, Switch1 is a Layer 2 switch.

PC-A sends a frame to PC-C. Switch1 does not have a mapping entry for the MAC address of PC-C. Which action does Switch1 take?

A.

Switch1 queries Switch2 for the MAC address of PC-C.

Answers
A.

Switch1 queries Switch2 for the MAC address of PC-C.

B.

Switch1 drops the frame and sends an error message back to PC-A.

Answers
B.

Switch1 drops the frame and sends an error message back to PC-A.

C.

Switch1 floods the frame out all active ports except port G0/1.

Answers
C.

Switch1 floods the frame out all active ports except port G0/1.

D.

Switch1 sends an ARP request to obtain the MAC address of PC-C.

Answers
D.

Switch1 sends an ARP request to obtain the MAC address of PC-C.

Suggested answer: B

Explanation:

In a network, when a Layer 2 switch (like Switch1) receives a frame destined for a MAC address that is not in its MAC address table, it performs a flooding operation. This means the switch will send the frame out of all ports except the port on which the frame was received. This flooding ensures that if the destination device is connected to one of the other ports, it will receive the frame and respond, allowing the switch to learn its MAC address.

A . Switch1 queries Switch2 for the MAC address of PC-C: This does not happen in Layer 2 switches; they do not query other switches for MAC addresses.

A . Switch1 drops the frame and sends an error message back to PC-A: This is not the default behavior for unknown unicast frames.

D . Switch1 sends an ARP request to obtain the MAC address of PC-C: ARP is used by devices to map IP addresses to MAC addresses, not by switches to find unknown MAC addresses.

Thus, the correct answer is B. Switch1 floods the frame out all active ports except port G0/1.
