Lab #5
For lab #5 you have to configure the routers interface, if you do not then you network cannot reach the eagle server (My Situation). To configure the routers you have to first setup the R2-Central router, which is the first router connected with the switch. You have to install an operating system for the Host PC and you need to install the terminal command prompt. After you install the operating system you go to the command prompt, and you type in the command INTERFACE, FastEthernet0/0 which then you add in the ip address given and turn the port on. My failure was the access the command prompt (A simple mistake which i hope i won't make in the future). My biggest failure of the lab which i now understand was to correctly read the instructions that are given to me CAREFULLY.
Lab #4
Lab #4 is basically lab #3 except you fully mastered the understandings of how to actually repair your network. You basically have to replace your "broken" devices (The Eagle_Server) with one that is configured correctly. When it says to replace it means to reconfigure and reboot the problem. That process is called troubleshooting, its something that 90% of the time you have to do when you first make a network. By troubleshooting the network, you will run simulation mode, which directly takes you step-by-step how the packet is traveling through the network. This helps you identify the problem accurately instead of actually taking the time to find the problem more physically. You repeat the simulation and also the trail & error process it takes to successfully send and receive a packet.
Lab #3 Reflection
Lab number three is basically to try and understand what went wrong with the network and to repair the problem in the network. You add in more numbers to the devices such as the gateway IP address and the DNS address which was the main problem of my network. I completely ignored the DNS server IP address, which is probably why the 2 routers didn't want to communicate with each other, it's imperative that you reach all of the requirements to components of the network if you want your server system to function correctly. Therefore, the problem was located in the transport layer which deals with TCP.
Lab #2 Reflection
In lab number 2 the main concepts were to determine if you configured the devices correctly so you can send a packet. The lab simply told you to diagnose the computer and to look at the scenarios when you send a packet to see if you successfully configured your network right. I configured all of the data that was given to me in the charts, after that i connected all of the devices together in the correct diagram. I turned on all of the ports, used the correct type of wire, and finally got all of the lights to go green.
Now was my part in lab #2 to send a packet from the Host computer to the Eagle_Server, without any type of technical difficulties. That's the main challenge and concept of the lab, to see if you know what you're doing instead of just randomly plugging in cables and typing random numbers. In this case, i did not complete the lab; therefore and i knew what the problem had to be. When i sent the packet over from the host to the eagle server, the packet successfully went through the from the host computer to the switch to the router. The packet did not however, travel to the second router. So right then i knew that the network was not working and i was just configuring with random numbers i did not comprehend with. Understanding what went wrong is the next lab.

Lab #1 Reflection
Hi!
For the first lab I learned how to use Packet Tracer, and the ability to configure and operate a server using 2 routers, 2 PC's, 1 switch, and 1 Eagle Server. At first, the task was a bit confusing because when i gathered all of the materials displayed in the lab, they were all red besides the 2 PC's and the switch. The problem was that i didn't correctly configure the routers with the servers. I also, had to setup the network and the network gateway using the 2 PC's (One of which, were the host). The settings to configure the devices were on the sheet of paper in the lab instructions and on the device itself (Of course).
After i had input all of the numbers in the correct device (including the gateway ip, host ip, and the subnet ip) there was still a physical problem with the devices. I had the switch the ports from off to on (Otherwise the device is just a simple piece of "brick"), after all that work the server was good and running smoothly. Now was the part where I diagnose the computer. I requested a message from the computer (Non-host) to the eagle server. I checked on bottom-right part of my screen to see the status of the message and the status of my network, and it was a successful connection.
As a result, i learned the main mechanics of how to operate the eagle server to be online, and to make the PC host communicate with the server using routers, switches, and cables.

My CISCO Student Career So Far........
Introduction
So far, if i were to rank my progress as a CISCO student i would say that i would have greatly improved by a TON compared to my grade last marking period. In the last marking period, i passed the class with a 77% which is a C; I currently have an 89% on my grade which clearly presents an improvement in the class.
Why am i Improving you ask?
The reason being of why i am improving is because I'm greatly improving my scores on tests. I find the tests to be more easy as i go through the course of the CISCO training and i has become very easy for me to understand networking. I would also like to say, I believe that the pre-test is impacting my motivation and effort that i put into the Actual examinations because the pre-test gives me a more general idea on what i should be studying on, why i already know, and what i need to know to pass the official examinations. If my instructor continues to give me pre-test, my grades would definitely, for a fact, increase my knowledge in the networking course and continue to gradually increase my grades and test scores.
How to continue to do better
All i have to do to keep my grades going higher is to do my work, study, and keeping a perfect attendance in class. All it takes to accomplish this flexible goal is motivation and self-confidence to know what my capabilities are and my limits. In reality, my capabilities are endless if i know how to accomplish it and to not abandon my objectives.
