Been a CCNA for over 6 years, spent hundreds if not thousands on study material and network equipment. This guy is next level. Free training and every email I sent to him with a question was responded to the same day. Unbelievable. All the other notable instructors are great, but as stated, this guy is next level.

Your voice and its recording quality, Your speech clarity for all types of listeners, the content quality, and the way you teach: Everything is perfect! Thank you for changing my life.

[Jeffway]

Many people say the CCNA is more difficult than Network+ but your course is so good that I had to choose to go for the CCNA just so you could be my teacher. We are all so grateful for your dedication to teaching us networking Jeremy!

[whowhat]

Every time I see your videos, it makes me excited. I want to shout out to the whole Networking world, Jeremy is the BEST!!! Believe me, there is no course on CCNA that can beat your this youtube free video course. I am saying this because I have completed the courses online that are regarded as the most valued and the most recommended ones- You are even better and beyond - love you man!!

[gabrielbendavid]

I most say this is the best CCNA course that I found on YouTube, the effort you put to explain every small detail is just amazing. You are really great teacher and I think that I speak for every one that we really appreciate that.

King of the teachers! You are bigger than my all university professors. If they think they're good at teaching, it means they still haven't met you.

One of the top CCNA channels on Youtube! The content is great, this is the perfect complement to my CCNA study. You are great Jeremy!

[adjaoudboudjema]

hello Jeremy, thank you so much for your effort, time, concentration, methodologies, even your clear English, (not only i'm learning the CCNA, but also I'm practising my English listening ). im a person with a physical disability, at first, I worried how I might in the future cope with the wiring cable problem, being my physical impairment, but after I discovered your channel i built up a stronger motivation to go ahead and turn the barriers into a force and learn more. Again thank you very much. I can say that what you are doing is a pure example of inclusion and sustainability goals. God bless you,

[IslamQ]

For the question 3:

PC4 to SW2: Src=4444, Dst=ffff
SW4 to R3: Src=4444, Dst=ffff
R3 to R2: Src=eeee, Dst=dddd
R2 to R1: Src=cccc, Dst=bbbb
R1 to SW1: Src=aaaa, Dst=1111
SW1 to PC1: Src=aaaa, Dst=1111

Thank you Jeremy, your course is very good and helpful.
Best regards.

[dirtywill]

Thank you so much for this material. I went from my A+ to my Security +. Not only is this teaching me how to work on CISCO products, but it is effectively filling in my knowledge gaps of Networking and where Network interactions relate to the OSI.

b) src/dst MAC at SW2 -> R3 segment: pc4 f0/1 - 4444, r3 g0/1 - FFFF
c) src/dst MAC at R3 -> R2 segment: r3 g0/0 - EEEE, r2 g0/1 - DDDD
d) src/dst MAC at R2 -> R1 segment: r2 g0/0 - CCCC, r1 g0/1 - BBBB
e) src/dst MAC at R1 -> SW1 segment: r1 g0/0 - AAAA, pc1 f0/1 - 1111
