Course Overview
Hi everyone! My name is Ross Bagurdes, and welcome to my course, Building and Troubleshooting a Network with ICND1 Skills. I'm a network engineer with 20 years' experience building and managing Enterprise networks and teaching people about them. This course was built to help people become as prepared as possible to earn that CCENT certification by taking the ICND1 exam from Cisco. In this course, we're going to review the most important terminology from the previous 13 courses, as well as build and troubleshoot a lab incorporating all of those ICND1 topics. Some of the major topics we're going to cover are reviewing the most critical terminology for that exam. We're going to understand your learning style, which will help you retain information while you're studying. We're going to design and build a network that incorporates all of those ICND1 exam topics, and then we're going to troubleshoot that network we designed to build those critical troubleshooting skills that are so valuable as a data network engineer. By the end of this course, you'll have the resources you'll need to study for and retain as much information as possible to take that ICND1 exam. Before beginning this course, I highly recommend watching and studying the previous 13 courses in the ICND1 series. After completing this course, you should feel comfortable moving on to the ICND2 study materials, which will help you prepare for the CCNA exam. I hope you'll join me on this journey to review ICND1 exam topics with the Building and Troubleshooting a Network with ICND1 Skills course at Pluralsight.

Review and Lab Network Drawing
Welcome to Pluralsight. I'm Ross Bagurdes. This course is Building and Troubleshooting a Network with ICND1 Skills, and this is for the CCNA 200-125 and 100-105 exams. In this course, we're going to review the last 13 courses, which will help get you prepped for the ICND1 exam, which will earn you your CCENT certification or Cisco's Certified Entry-Level Network Technician. In this first module, we're going to do some review of protocols and concepts and then introduce the lab that we're going to use for the rest of the course to build and troubleshoot the network with all the skills that we've learned so far. So our goals in this module are to, first, review the OSI module and TCP/IP model and the protocols and concepts that are assigned to each layer. Now we have done this before in a previous course, but I want to just reiterate the importance of it, and we're going to go through the mapping of those protocols once again. Second, we're going to describe the ICND1 lab network that we're going to use and then take that network and create the drawing and label it with IP addresses, device names, interface names, and other information that's relevant so that we can go build our network and do some testing, troubleshooting, and observation of how all these protocols interact together.

Building the ICND1 Lab Network: Routers
Welcome to Pluralsight. I'm Ross Bagurdes. This next module, we're going to start building the ICND1 lab network that we designed in this course. Since there's a lot of configuration going on here, we're going to start with the routers. This next module after this we'll do the switches. If we look at our goals this module, we're going to start by building this ICND1 lab network. We're going to start with just the routers. And what I'd like to do here is use a combination of the routers and Notepad to help us build the configurations that we can use on these devices.

Building the ICND1 Lab Network: Layer 3 Switch and Switches
Welcome to Pluralsight. I'm Ross Bagurdes. In this module, we're going to build the rest of our ICND1 lab network. And we're going to focus here on our layer 3 switch and the layer 2 switches. Our goals this module are going to be the same as the last module. We're going to build that ICND1 lab network now focusing on our switches, and we're going to use Notepad to help us build those configurations for those switches. Let's just dive into it and start configuring our switches.

Testing and Examining Our Network
Welcome to Pluralsight. I'm Ross Bagurdes. In this module, we're going to test and examine that network we just configured. The goals here are to test and examine our configuration, and we're going to use ping commands, traceroute commands. We're going to SSH into the devices and issue some show commands as well. If along the way we discover any issues in our configuration, what we'll do is we will correct those issues so that our network functions as we expect it to.

Adding Services
Welcome to Pluralsight. I'm Ross Bagurdes. In this module, we're going to add some services to our network. Our goals here are going to be to add port forwarding Network Address Translation so that a device on the internet can access our web server at 10. 0. 80. 80. Additionally, I want to create an access control list to protect our web server so that we're only allowing traffic on port 80 to reach that server. And what that'll do is it'll help protect the server from attacks on port numbers, TCP port numbers, that aren't port 80. We only need port 80 for this web server to work, so we're going to block everything except port 890.

Troubleshooting Our Network
Welcome to Pluralsight. I'm Ross Bagurdes. This next module we're going to do some troubleshooting. What I've done is I've created some bad config files for each of the devices, and I've uploaded those to the download section of this module. So if you are interested, you can set this network up yourself. You can load on all the bad configuration files that I have put in that downloads folder and then do your own troubleshooting of this network until you figure out what's wrong. Should you get stuck or want to know how to solve the issues that I've created in that network, were you can come back and watch the video, and I'll step you through each device and show you how I'm troubleshooting and solving the problems based on the complaints users are experiencing. The goals for this module are really to just do some troubleshooting of network issues that I have created for you. In that downloads section, I have put both the broken config files and the correct config files for each device. So if you want to play the game and do some troubleshooting on your own here, you might have some fun with this by putting all those bad configuration files on your devices and trying to do some troubleshooting on your own. Come back here, and I'll show you how I solved each of the problems. Hopefully you'll learn something about how to walk through and solve network issues in a data network system like we have here for our lab network. Let's get started.

ICND1 Exam Tips
Welcome to Pluralsight. I'm Ross Bagurdes. This last module in our ICND1 wrap-up course is going to focus on some exam tips for you. Now that ICND1 exam will earn you the CCENT certification or Cisco Certified Entry-level Network Technician. Our goals this module are to discuss prepping for that ICND1 exam. One of the things I'd like to talk about are some learning styles that you may or may not be aware of. I'm going to encourage you to incorporate as many learning styles as possible in your preparation for the exam. And I'll discuss some resources you can use to find out what you're learning style is best at. And then you can use that to your advantage when you're preparing for this exam. Second, we'll talk about scheduling the exam, and I'll show you where to go on the Pearson VUE website to do that. Then we'll talk about taking the exam. And I'm going to go over what you can expect when you show up in that room, as well as some of the question styles. Now I signed an agreement with Cisco that says I won't tell you what questions you're going to be asked, but I have created some questions that are in the style of Cisco questions, and we can take a look at how we might go about solving those.
