Packet Tracer lab 1.1.5.3

This lab requires us to use packet tracer to practice determining the proper cables to use. In cabling devices the media being used is most relevant, whether it be LAN or WAN, the cabling issues will vary depending on the scenario. With you connect devices you must verify the connection through actions, such as sending a packet. Usually you are urged to use an auto connect tool, but in this lab in particular, for obvious purposes, you must determine what media to use your self. After everything is connected run a test to see if you are correct and troubleshoot otherwise.

Packet Tracer Lab 1.1.4

This packet tracer activity revolves around using the setup mode and tests our ability to properly configure routers.We investigate the show running-configuration command. This command can be used to help verify and troubleshoot some of the basic hardware and software components of the router. We use this command in the lab to display the information about the of the Cisco IOS software currently running on the router as well as the version of the bootstrap and the information about the hardware configuration, including the amount of system memory. On the other hand setup mode is initiated if the startup configuration file cannot be located, the router will prompts the user to enter setup mode. Setup mode involves Setup mode is a series of questions urging the user for basic configuration information. Setup mode is not intended to be used to enter complex router configurations, but in the case of the lab it is required.

  This packet tracer activity shows a complex network of routers with many different technologies. We view the activity in simulation mode in order to see the traffic traveling from multiple sources to multiple destinations over various types of media. It is enforced that the routers are used to determine the path of the packet and forward the packets, without this knowledge you cannot properly complete the configuration of the routers. With a properly configured routing table we can follow a packet from source CPU to the destination CPU.

Packet Tracer Lab 1.5.1

This packet tracer revolved around cabling a network with routers, switches, and hosts. Once we setup the network according to the desired scenario, the router needs to encapsulate the packet into the data link frame of of the outgoing interface. The switching function is a process used by a router to accept a packet on one interface and forward it out on another. A key responsibility of the switching function is to encapsulate packets in the appropriate data link frame for the outgoing data link. Therefore layer 2 data link addresses must change at every hop as the packet is decapsulated and re-encapsulated in a frame in each router.

HW 2/27/12

For stage 2 of the assignment today, we were required to assign a task to each group member. Corresponding to the task would be a component, such as me i was number 3 and therefore assigned the ROM component. Then we would simulate the journey of a packet through the network among our group. For example "copy ios" command would be recorded by the ROM then given to the CPU and then sent to either the RAM or NVRAM. This setup would apply for several different commands and the path of the packet would vary with each command.

Web Seminar Essay

         On thursday we participated in a web seminar, conducted by a senior vice president of cisco, carlos dominguez. He gave us insight on how the journey to reach cisco is and what it takes to get there. He told us about the benefits of being enrolled in the cisco academy. As well as the culture of technology and how to adapt to the constant changes of it.
        There are various benefits to being enrolled in the cisco system as a student. It gives us access to the Cisco curriculum and contents so that we will be able to use that directory to properly assist us in either cisco labs or other programming dilemmas we may encounter. Not only does it have information to offer but it also acts as an interactive blog and if you cannot find your desired information, you can ask a question to the cisco community and receive a message as a response. It is also helpful for us to receive access to job listings as well as a calendar updated with various events and of course certification testing dates, which is very crucial for our class. As a result their are many advantages to being enrolled in the cisco system.
          Carlos Dominguez told us to follow our hearts and our minds in order to achieve our goals. He also told us to tap into the constantly changing world of technology through social media. He also gave us insight on how to persevere and motivate yourself through your obstacles to meet your ultimate task. He also discussed his passion for video production and how their are many fields of cisco that pertain to each of your desires.
          In conclusion Carlos Dominguez has inspired me to work harder and achieve my goals no matter what the obstacle. I would be delighted to experience another web seminar such as this one in the future. He has motivated me to add to my determination and further pursue my career in cisco.

CCNA Case Study Chapter 8

A) External Interface
B) The external interface will create sound waves and disrupt the previous ones leaving the user without desired signals
C) if their is a possibility that the alarm clock will once ring next to the unprotected cables then a different result would be achieved.
