You just turned on a four port Ethernet switch (it hasn’t learned any addresses yet) and connected a host to each port. You send packet #1 from 00:11:22:33:44:55 to 66:77:88:99:00:11 which arrives at port 1 of your switch. Next, packet #2 is sent from 22:33:44:55:66 to 00:11:22:33:44:55 which arrives at port 3 of your switch. Which of the following are true?
1. Packet #1 is broadcast on all ports
2. After the first packet is received, the switch associates 66:77:88:99:00:11 with port 1
3. Packet #2 is only sent out on port 1
4. Packet #2 is sent out on ports 1, 2, 4

Answer:

Option 2 is correct.

Explanation:

When the user recently switched over that port Ethernet device, which is, no addresses have yet been acquired as well as a client has been linked on each port. He sends #1 packet from 00:11:22:33:44:55 to 66:77:88:99:00:11 arriving at the device's port 1. Next packet #2 is transmitted between 22:33:44:55:66 to 00:11:22:33:44:55 that appears at the switch's port 3.

So that the Package # 2 will be sent only through port 1 by the user who switched over the network.
