We're already off to a bad start. Question 3, hubs are not layer 2 devices. They do not distribute traffic based on MAC addresses, they simply forward traffic through all ports as a broadcast which makes it a layer 1 device. Routers operate on layer 3 (IP) and Firewalls can be layers 3,4 or 7. The only correct answer is B) Switch. If you're going to make Network+ videos you need to make sure your information is accurate.
Hub was listed as a layer one device in the material for network+
It is listed in seection 2.1 layer one device.

When did hub become a data link device. Misleading!!
I am thinking the same. Wrong informaton.
@@sh14home it is listed in section 2.1 for the network+ as a layer one device
I got confused too
I wonder if you have done CompTIA network+. Some of them are wrong.
Congratulation Helena. I'm studying I'm trying hard. I'm sure I won't pass it. 😢
You got this! We’ll both pass 😎👍🏻
Can you please make more videos like that for comptia network + N10-009 which is the newest version. Please please please please!
