VLANs and Trunking - CompTIA Network+ N10-009 - 2.2

- - - - -
VLANs can be used to create a separate of broadcast domains on a single switch. In this video, you'll learn about VLANs, 802.1Q trunking, and managing both voice and video across the same connection.

Thank you for such succinct explanations!

I'm in the beginning of my IT career, and was surprised when little was know from professionals on VLANs and how they work. VLANs are important and are now audit findings ready for he making if your network is not segmented properly.

Lol, I was literally setting up my home Internet with vlans before I saw this

How does separating VOIP and data into separate VLANs improve performance if they are still travelling the same connections/devices? Wouldn't congestion affect them all the same?

[tonioval]

Thank you professor! If the data VLAN is untagged does this mean that it is the native VLAN or just similar to it?

Is this something that's practical for an average home internet user? I have a 16-port switch that I just plug all of my stuff into. That switch is connected to the router, which is then connected to the modem.

i assumed VLAN tagging was physically port-based in a switch. however the last example of the shared cable for a VoIP phone and computer seems like there is some additional methods for either logical port/address sorting? is it only an L3 switch feature?

Hi professor messer, does trunking involves connection and communication with different VLANs (like in example you explained vlan 100 and vlan 200 on switch 1 and other was also the vlan 100 and 200 with other switch, so can vlan 100 and 200 on one switch communicate with vlan 300 and 400 of other switch using trunk?) or just same VLANs apart
