When you select 'ask your question' a box will appear and it will ask you to write your question. Underneath the text box you'll see a 'pi' sign and an 'omega' sign and next to that you'll see a paperclip sign. Click the paperclip sign and then choose the file/s you want to attach.
I have attached a docx (document) if you don't get what i mean.
Hope it helped :)
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.
The correct answer is true :)
