  • Hi Jeremy, first off i'd like to thank you for all the work that you have done for the CCNA and the current work on the CCNP it really motivated me to completely change my carrier perspective.

    Secondly, could you tell which software do you use to make those schematic i feel like you take a screenshot from GNS3 then add arrows or checkboxes and then bring everything inside a powerpoint that you present on the video, am I right ?

    Still thank you and have a nice day

  • hello dear. would like to educate me how the MAC address of the routers will be known to each other while routers exchange packets between each others if ARP is meant only within LAN, because packets have to apply layer two encapsulation .

  • Hi Jeremy, I have an inquiry Do we need to config DHCP snooping to be able to use DAI?

  • hey, Jerry …this is the first video I watched on your CCNA playlist. And it's extremely effective and useful. You explained everything in 30 minutes. I really appreciate you making these high quality video available freely on YouTube.😀

  • a very minor point: @ 12:39 dhcp is mispelled in the second line, although it's clear what it means

  • Hi Jeremy, i have a question here about DAI optional check at 16:00 with also that example.
    DAI won't check the message on trusted port, when PC1 send ARP request to SRV1 and SRV1 send response, the ARP response won't be checked on SW1, right ? How is the optional check work if the ARP response won't be checked ? Or maybe when we configure the optional check, the ARP response will be checked ?

  • So the switches don't inspect traffic on untrusted ports going to the device? Only those leaving, correct?

  • @Jeremy's IT lab when they ask to define explain give the characteristics of certain concepts does that mean we should be writing them down or it's multichoice questions only

  • many thanks to teacher Jeremy, a great teacher, every lecture is well designed, in depth, detailed explanation on command information.

  • With thousands of security measures in place hackers always find their way into networks! Something is missing…

  • Thanks J always grateful for the knowledge you share. Bless

  • Hi Jeremy, you made the difficult topics so easy to understand and I watched all your videos so far and was able to pass my CCNA exam today! I could not have done it without your video series.

  • Hello, Jeremy. If I learned all the videos that you've posted. Am i good to go for the CCNA exam?

  • Recently got a really good paying job in networking and I could not have done it without these videos. Experience is limited but passing my CCNA using your course helped opened these doors for me. I feel like I owe you part of my salary lol As long as these videos keep coming I will keep watching! Thanks again Jeremy!

  • Hi Jeremy! Do you use Wendell Odom books when preparing your videos? I want to understand if I should read his book?

  • Jeremy, just wanted to say thank you for all your lessons. I passed my CCNA exam a couple days ago thanks to you and your videos! So, thank you again for all you do!

  • Hey man, I enrolled in your lab course and I’m about to buy the other course. What’s the advantages of the website course vs YouTube vids. Will this course properly prepare me for the CCNA or get me close enough to pass?
