i just can't understand why you only have 253K subscribers, you really deserve 5 millions at lease.

Amazing. I'm brand new to the world of IT and making a mid-life career change form the medical field and I have to say the granular care and attention he puts into these explanations is absolutely essential to my understanding. Most instructors I think lose touch with the beginner's mind because they have lived so long in the world that they are trying to describe to the newcomer, but David seems to have an intuitive understanding of the more conceptually challenging areas in these technologies, and approaches them with tenderness and understanding I've seen from very few instructors in my lifetime. Bravo!

You are an ingenious teacher ever ! Lots of Love and Respect.

Aaah! Now the penny dropped! 13 years after conpleting my CCNA. I just thought of the port numbers on the server side and never thought of the port numbers on the client side.

It is nice to just go through the content, refresh my memory and see what changed. (Without the stress of exams in my case ;) )

Wish I came across your channel earlier.

[BeeBumper]

I have been taking your CCNA course on your website, I booked my exam and have been doing some practice tests, most of the time I have no problem verifying why some answer is not what I thought it would be but this one sticks in my side and I wanted to know what your feeling on it is:
The question is quite simple really:
What command configures a switchport using the default Vlan?

I think because all ports are in vlan 1 by default that just making it an access port is all that you need to do, and that is debatable as it is usually by default an access port anyway.

So I said "switchport mode access", rather than "switchport access vlan 1" because the ports are in vlan 1 by default. Any other vlan, I would say "switchport access vlan X". The answer is supposed to be "switchport access vlan 1" but to me that is redundant, and unless specifically stated it is in another vlan, this would be unnecessary. Am I over-complicating this question?

[michaelbryant]

Omg I just realized the PDU is the OSI model. This helped so much! Reading about it for months lol
