Studying for CCNA Update
It has been a while since I have written a post about studying for Cisco's CCNA IT certification.
To be honest, progress has been slow.
However, there are reasons for that.
Back in late December 2024, I had just completed the reading the following chapters in the CCNA 200-301 Official Cert Guide, Volume 1, Second Edition by Wendell Odom, CCIE No. 1624.
- Part One: Introduction to Networking
- Chapter 1: Introduction to TCP/IP Networking
- Chapter 2: Fundamentals of Ethernet LANs
- Chapter 3: Fundamentals of WANs and IP Routing
- Part Two: Implementing Ethernet LANs
- Chapter 4: Using the Command-Line Interface
- Chapter 5: Analyzing Ethernet LAN Switching
- Chapter 6: Configuring Basic Switch Management
- Chapter 7: Configuring and Verifying Switch Interfaces
I also completed the exercises for Chapters 4, 5, 6, and 7 in Pearson Vue's CCNA Network Simulator training program. Furthermore, I even completed all of the exercises for Chapters 4, 5, 6, and 7 on Wendell Odom's CCNA Skills Blog. Do you need to use Pearson Vue's CCNA Network Simulator while studying for the CCNA IT certification? No, you don't. However, the CCNA Network Simulator does come with A LOT of guided practice exercises to get you experience using Cisco's IOS command-line interface for configuring switches and routers. In other words, using Pearson Vue's CCNA Network Simulator is completely optional. However, I believe that the money spent on Pearson Vue's CCNA Network Simulator is money well spent.
For CCNA study, Wendell Odom's CCNA Skills Blog is also entirely optional. The CCNA Skills Blog contains a lot of good resources for studying CCNA. Moreover, the CCNA Cert Skills Blog also features Wendell Odom's own CCNA practice exercises. While Pearson Vue's Network Simulator is a simulation, Wendell Odom's networking exercises require you to use Cisco's Packet Tracer program. Unlike the Network Simulator, Wendell Odom's networking exercises are entirely free. Plus, Cisco offers Packet Tracer as a free download from its website. You do have to create an account with Cisco to download Packet Tracer, however. It's irritating, but Packet Tracer is an invaluable program to have in your CCNA study.
What was the problem?
Despite reading the first seven chapters in the textbook and completing all of the exercises, what was the problem?
Since I had recently earned four training badges from Cisco Networking Academy (see previous post here), I was probably feeling a little too high and mighty when it came to basic networking. Thus, when it came to reading Chapters 4, 5, 6, and 7 in the CCNA 200-301 Official Cert Guide, I just read through the chapters without taking any notes. I was about to start Chapter 8: Implementing Ethernet Virtual LANs, when I realized that I probably committed a mistake by not taking any notes while reading those four chapters.

Chapter 7 from the CCNA Official Cert Guide |
Thus, I made the decision to RE-READ all four chapters and TAKE COPIOUS NOTES. After re-reading each individual chapter, I went back to the Pearson Vue Network Simulator and completed the exercises for each chapter. To be sure, it was A LOT of work and required a lot of extra time. However, it was a necessary review to complete.

Chapter 8 from the CCNA Official Cert Guide |
After all of that hard work, I was ready to start reading Chapter 8: Implementing Ethernet Virtual LANs. This time, there would be a difference, however. I would take notes as I read through the chapter. Predictably, taking notes while reading prolonged the amount of time it would have taken to complete the chapter if I had just read it. In the Introduction to the CCNA 200-301 Official Cert Guide, Wendell Odom mentioned that he tried to write each chapter so that it would take approximately an hour to read. That was an interesting comment, I thought. Whenever I read something technical, I tend to read slowly as I try to absorb all of the information. At over 30 pages, Chapter 8 is one of the longest chapters in the CCNA 200-301 Official Cert Guide.
Why is Chapter 8 so long? Well, the chapter covers two topics. The first topic concerns what are known as virtual LANs. What is a virtual LAN? A virtual LAN is created when you essentially subdivide a switch into smaller segments. A typical switch has 24 ports. For example, let's say you have a small business with several departments, but you only have several departments, such as accounting, operations, sales, human resources, and so on. To improve security and network efficiency, you decide to group all of the devices used by the accounting department into a specific range of ports. Then, you do the same for all of the other departments. There is a problem. When you create a virtual LAN, the switch recognizes each virtual LAN as a separate network. You can't just send a message from a device on VLAN 1 to another device on VLAN 2 even though you are using the same switch. It just won't work. To send a message to another device on another VLAN on the same switch, you need a router. After all, the VLANs are located on different networks. That's where trunking comes in. Essentially, trunking identifies what VLAN the message is being sent to. Thus, you have to adjust the settings on the switch and the router to enable trunking, which will then allow devices on separate VLANs to send messages to each other.
Yes, it's
A LOT of information to digest as you are taking notes. However, I eventually made it to the end of the chapter. When you take notes while reading, the process makes you concentrate on what you are reading.

Pearson Vue Network Simulator Chapter 8 Exercises |
Now that I have completed reading and taking notes on Chapter 8 in the CCNA 200-301 Official Cert Guide, I have been slowly completing all of the Network Simulator exercises for Chapter 8. The Network Simulator contains three types of exercises for Chapter 8.
- Skill Builders
- Configuration Scenarios
- Troubleshooting Scenarios
So far, I have completed all 13 Skill Builder exercises. I recently completed all three Configuration Scenarios. Now, I just need to complete the remaining four Troubleshooting Scenarios. Once all of the Network Simulator labs are complete, it will then be time to either move on to Chapter 9: Spanning Tree Protocol Concepts or head on over Wendell Odom's CCNA Skills Blog and work my way through his VLAN exercises.
Sounds like fun, doesn't it?
