Keith, you are a phenomenal instructor. I've taken the entire 200-301 curriculum over 3 quarters of community college, and had ZERO IT understanding going in, didn't even know what networking was, really. Needless to say, I missed a lot, and now, using your videos and labs for review, a lot of concepts are making more sense. Thank you so much.

Barely could use a computer and now in just a few months in college Cybersecurity I've learned a ton but processing it all is difficult so I like to watch people explains things better than self teaching in college.

HI Keith, I have actually been studying for the 200-125 CCNA the past month and unfortunately I have not been able to master all the concepts yet. I'm about 3/4 of the way there, but I feel like at this point i'm better off saving my voucher for the 200-301. I'm going to be relying heavily on your videos here and on CBT nuggets to pass exam within the next 2 months. I may just buy Todd Lammle's new 200-301 book to replace his current 200-125 I've been using. Do you think just the videos would be enough? Keep up the good work and thanks for taking the time with these vids

Hi Jorge. The CBT Nuggets are very thorough, and should be enough. Having a book as a resource is also a good idea for additional insights for any topic you want to dive into a little more. Glad you are here, and happy studies! It is worth the effort.

Thank you for the question R T. Jeremy's IT Lab courses are wonderful! I would recommend at least 1 book as a reference as well. Check the feedback on Amazon regarding books, to make sure others are recommending it as well. I've heard that Lammle's book is a good one.

[@hdot4258]

Hi guys, quick question. I'm a complete newbie to the world of IT. Is this course the right place for me to start or should I be getting a ComptiaA+ first. I'm so confused and all help is appreciated. Thanks!!!

[@KeithBarker]

Thank you for the question. If you are brand new to networking, you may want to consider CompTIA Network+ followed by the Cisco CCNA. There is quite a bit of overlap, which is good for reinforcement.

[@ErichBProductions]

It's interesting you say we don't need to memorize the OSI model. All the other resources I've used to learn networking emphasize the importance of knowing the OSI model because it's the model most network engineers use for communicating issues on a network. Would you say TCP/IP or the "actual" model is enough for the CCNA but we should know OSI for working in networking or is TCP/IP /"actual" model enough even when diagnosing network issues?

[@KeithBarker]

Thank you for the question Erich. What we use today is a mashup of terms and layers from BOTH the OSI and DOD model. Final result is: Application Layer Transport Layer 4 Network Layer 3 Datalink Layer 2 Physical Layer 1 And it is important to understand the layers above for designing, managing, and troubleshooting networks. Cheers!

[@ytfamily000]

Hey Keith. I came across your series thanks to Jeremey's IT Lab. You're both amazing! I'm just wondering, how did you decide on the order of videos? Is it based on the CCNA 200-301 official exam guide, or something else? Also, is your course enough to study from (along with Jeremy's I guess), or do you suggest other materials/sources too? I know you're on CBT Nuggets but not sure of the difference between materials. Last question: is video 66 (or 68) the last video in the series or will there be more? Again, many thanks!

[@KeithBarker]

Thank you for the question. I add several videos to the playlist each month. Not intending for this to be a sole study solution, but rather to help those who are studying.
