Well done, Jeremy. This is one of the best sequences I've seen to explain a rather complicated topic. Great work!

[@JeremysITLab]

Cheers Ed, thanks!

My 2 favourite YT CCNA Channels!!! Love all your work!

[@alex1949]

I earned my CCNA! Thanks to your videos and the vol 1&2 cert guides, I passed with ease after 3 months of study. My background is in IT, but on the PC and server side. My networking experience was limited to setting up simple static routes, 2 VLANs and DHCP relays by looking at KZbin how to-s and copying commands. I really didn't understand the commands I used at the time. I am much more capable now. Looking forward to your CCNP course!!

[@konefine3626]

Hi, did you do a full time study or studying while still working? Just curious , thanks

[@alex1949]

@@konefine3626 Both. For the first 2 months, I studied about 2 to 3 hours a day. A little more on weekends. I went through all of Jeremy's videos, but skimmed through the few chapters in the book I felt I already knew. The last 10 days I had time off, so I studied full time.

[@konefine3626]

@@alex1949 Thanks for sharing that

[@anonymous95990]

so is this series and vol 1&2 cert guides enough for passing the CCNA? were these your only resources?

[@alex1949]

@@anonymous95990 What ever wasn't clear to me enough, or if I wanted another explanation from a different perspective, I would Google that particular area. I did not use any other resources otherwise. The 1&2 guides gives you access to more study questions, similar to the quizzes Jeremy gives. For me, it helps to know WHY the other answers are wrong, not just which one is right. If I know why its wrong, then I understand the subject.

[@daudhn]

I love the way you present and explain the materials in all your videos- very clear and easy to follow. Thank you very much Jeremy! Keep up the awesome work!

[@FIREfreezerPR]

It's nice to have a brain-break after the intensive last couple of subjects. Still important information though!

14:31 The data center that Jeremy works at must be the best run data center on the planet

[@XxThePlaylistxX]

I work with a 3-tier architecture and it's so simple to scale and work with. Spine and leaf seems like a cabling nightmare but I know data centers usually have a better system for managing that, sometimes they just run all the dark fiber beforehand to accomodate for expansion because the most expensive part of installing cabling is the labor, not the materials.

[@YakuLin]

Hello, Firstly, thank you so much because I pass the CCNA yesterday. Now I am just rewatching this video to fill the gaps in my knowledge and I have a question. How does a Spine-Leaf architecture connect to the internet? Are the core routers connected to Spine or Leaf switches? Big thanks!

[@リンゴ酢-b8g]

CONFIRMED. a common question in the exam: In Which way does a spine and-leaf architecture allow for scalability in a network when additional access ports are required? A. A spine switch and a leaf switch can be added with redundant connections between them. B. A spine switch can be added with at least 40 GB uplinks. C. A leaf switch can be added with a single connection to a core spine switch. D. A leaf switch can be added with connections to every spine switch. and teh answer is A leaf switch can be added with connections to every spine switch. almost word for word according to jeremy's explanation

[@ahmedlateef5244]

Many thanks, Jeremy.

Hello Jeremy. First to say massive thank you for all your videos. I currently just finished Day28 OSPF. Still long way to go, but I enjoy every video I watch, and thank you for that! My question is how many videos is left to create to finishing full course? Just wandering in with position I'm in full course perspective. Thanks again Jeremy.

Well done, thanks !!!

[@Hartley94]

Thank you so much.

[@bakig.5961]

The core layer serves as the aggregator for all of the other campus blocks and ties the campus together with the rest of the network. So, it should be better not to use the word "aggragate" for Distribution Layer.

Jeremy, Can we use bosons netsim at the start of learning for CCNA, or we need to first get through (books or your videos) and then go for Netsim and Exsim ? Great Course as always, mad love

I recommend using NetSim to practice labbing whatever topics you have been studying from the course/book you're following!

How does STP function in the Spine Leaf architecture? Since the Leaf's are L2 and the Spines are L3 you have to use just a normal L2 connection between them right? Therefore wouldnt the redundant connections be disabled?

[@Neophage]

Now that SOHO's been covered, I've started wondering how exactly that connection from router to "The Internet" actually looks in an enterprise environment. I don't presume there's such a thing as an enterprise modem, is there? Never mind, you basically answer this in the next video.

Probably not, it's not in the exam topics list.

[@maciekb.4354]

@@JeremysITLab Thanks for your reply, the reason for asking is when I ran a prep test from Pearsons it threw at me questions about E-Line, E-LAN and E-Tree lol

[@mzalg3932]

Hello, Please I've a question: as you mentioned in a 3-tier design, STP should be avoided. but as per the diagram, each core switch is connected to each distribution layer switch. In this case how we will avoid loops between distribution and core layer switches ? Thanks.

[@braveheart1320]

I might be a little late, but generally distribution switches will not be switching on layer 2, but will rather be switching at layer 3 with SVIs (switch virtual interfaces). This prevents a layer 2 loop/broadcast storm from occurring, whereas with an access layer switch, they will generally only be operating at layer 2. Hope this was helpful!

Each A connects to each B implies each B connects to each A😂

[@marcusclaudius266]

I'm a little confused by the Boson question. Is it possible for A to be true, but E not true? It's a bit confusing for them to say pick 2, but then the correct answers is just saying the same thing twice.

[@JeremysITLab]

Yep, stating the same principle in two different ways. But they're the only two correct choices!

with all respect sir could u just put some words about Cisco ACI just to make us more confortable with this terms Thx any way :)

[@cnps235]

We can't just find more clearer than your courses for the CCNA Mr Jeremy. However, even if we are very thankfull, you gotta see how to structure your courses so the basics won't come the latest as the 100th video of LAN architectures and there's no wireless subject relatedd too because Wireless is a big part of the questions we encounter in the exams ...

[@JeremysITLab]

I ordered it this way on purpose because there is no need to learn it right away, and there are many concepts in this video that would be impossible to understand at the beginning: PoE, QoS, port security, IP phones, STP, HSRP...if you don't know those topics, you won't understand how they fit into LAN architectures. The Cisco Official cert guides place this topic near the end too, by the way. There are no wireless topics yet because the course isn't finished yet.

[@cnps235]

@@JeremysITLab, thanks for the answer ! I admit that explained clearly like that it makes sens ... howerver, i was just sayind it like that because in the description of the exam topics list, they classified all those topics of topologies and WLC as networks fundamentals so i said to myself that they may be pre-requisites but thanks for the explanations, really appreciate it. To end this free series of discussion :) i I would just ask you to marvel us with the series on the WIRELESS, we can not wait to go through it ! Many thanks !

[@tikshuv-ccna]

It's very controversial the thing with order. Order can be historically based, or logically based, or from general to specific. I think Jeremy took an interesting order, like flowing and understanding networking also building the concepts on top if each other not just being logical or general/specific thing. About the wireless i dunno maybe it can come earlier.
