CCNA BOOT CAMP TRAINING with 4 Certifications

❶However, the CCNA Routing and Switching is still the most valuable and it is a prerequisite if you would like to specialize in Voice, Video, Security or something else from the available Associate-level certifications.

We have to identify all those different components and how we will connect them together. And most importantly, we have to understand how communication flows from one end of the network to the other end. Take a moment to think about all the electronic devices that you have access to, whether it's your phone or whether it's your television or whether it's your PC. What do they all have in common? Different components that make them work. But those components are nothing without one thing, and one thing that's very important, and that is the operating system.

When we think about our switches and routers in the Cisco world, we just have a bunch of components inside of the box, what makes that box tick is that operating system, so we will focus on Cisco IOS. Every electronic device we purchase will have some initial configuration on it.

Now is that the initial configuration we will use in the real world? We always want to make those modifications to make that device meet our needs.

And this is what we need to do here as well with our switches. We need to ensure that it has the most appropriate host name we can manage it across remote networks. We don't always want to have to connect to the other console cord. So we want to specify management IP address so we can connect to it. We also want to be able to double check to make sure that the boot up sequence is correct, that everything is working properly on our switch. Hope you are saying layer 2.

So we find our switches at layer 2, but how do we connect all these switches together? What are we going to use at the physical layer of the OSI model? There are different types of cables we can utilize.

It's important that we choose the correct ones for our needs. So we will spend our time at layer 1 and layer 2 of the OSI model focusing on encapsulation methods, we could utilize to ensure that we have communication between our devices in our local area networks.

When is Internet Protocol version 4, or IPv4, going away? Internet Protocol version 6, or IPv6, is definitely its replacement.

But when will that happen? There is no set date, there is no light switch that will be turned on or off that says: Even though we know that Internet Protocol version 6, or IPv6, is on the horizon, we still need to be proficient with IPv4 — addressing and subnetting. Will you take one large address block and just associate it with one portion of your network or will you be creative and be efficient with those IPv4 addresses because they are scarce and make sure that you separate them into their different logical networks, break them up through subnetting.

If you are not familiar how to do that, we're going to teach you how to do that later in the course. Can we no longer subnet it anymore? No we can, and this is known as variable-length subnet masking, or VLSM, and what is it? It's really just us subnetting a subnet. After we've focused on layer 1 of the OSI model, layer 2, layer 3, let's keep moving on up. Let's focus on layer 4 of the OSI model, which is also known as the transport layer.

Two protocols we will focus on specifically here, TCP and User Datagram Protocol, or UDP, we will compare and contrast them and we will learn when and why we use each of them for transportation.

And then we will dive into something we have all been waiting for, the operation of our router. We will look at how our routers come to us in the box, how we will set them up, configure them and the basic operations of them.

Then we are going to cover one of the most important concepts here! We are going to discuss packet forwarding. How do we send that packet from one end station all the way to another end station that's in a completely different network? So we are digging into our router now. And we are going to focus on what happens when that packet arrives at the router, what it is going to do in order to make sure that it continues on its journey to its destination.

We will have to focus on something else as well, that is the concept of routing and how we train our routers. So here, we will introduce you to static routing and how we can manually train our routers to ensure that they know what to do when the packet arrives.

Later on we are going to focus on access control list a few different times here in the ICND1, why are we doing that? One thing though that they might not be very detailed and would just get you home. If you really need to get the understanding and go deep this is how I would suggest preparing -. For the topics and notes that you study from OCG, go through Chris's videos and fill in the gaps. Get more notes done. Get their bundle which comes with their CCNA workbook as well.

Get your hands dirty at the CLI. So the way the prep should be done for any certification level is to start with the basics, hon the basics and then when you have a good understanding go deep and practice as much as you can before you attempt the exam.

I'd also give a huge thumbs up to Chris Bryant. I've never been the biggest fan of having to read the huge books we need to, so being able to watch the videos many times and then jump onto Packet Tracer to have a play was ideal for me.

I started with DansCourses on Youtube. But I am always open to and looking for more information, and learning materials. I found them, But am not able to spend I did spend They were just moving too slowly, got bored. So I look further, and find YouTube videos And build my own LAB at home..

I have a few Cisco devices here. You just have to wait for the reduced price, they do it at least every month! You might also like the Premium section here. You get tons of videos plus Cisco Learning Labs! The Complete Course - Udemy. Chris' is more comprehensive, but anyone who's seen Laz's videos will know that he has a style of presentation that can sometimes make complex subjects just 'click' when he explains them.

Perfect example is his free YouTube video on IP addresses and subnetting:. Thanks for those two links!! I couldn't say no at those prices. But if anyone else wants them at those prices the offer ends today July 6th. If you're someone who grasps things better by the use of an analogy, I found the guys at CBT Nuggets often came up with some good ones that would make the topics suddenly become clearer for example DLCIs likened to exits on the highway or gates at an airport.

I would have liked to take out a subscription, but I personally found it a bit too expensive for me. They do however offer a free trial and I took advantage of that in the run up to my exam.
