Scenario In this lab‚ you will design and configure a small routed network and verify connectivity across multiple network devices. This requires creating and assigning two subnetwork blocks‚ connecting hosts and network devices‚ and configuring host computers and one Cisco router for basic network connectivity. Switch1 has a default configuration and does not require additional configuration. You will use common commands to test and document the network. The zero subnet is used. All contents are Copyright

plan consists of the physical and the logical views of the network. A physical network is the hardware such as cables‚ switches‚ hub etc. A logical network is the addressing used to connect these devices Job brief-secure wireless network for a coffee shop You need to install a wireless network for a coffee shop. They require certain network devices such as a firewall‚ router computers etc. It is a coffee shop where they want a wireless access point for their customers to login while drinking coffee

One could personally see the switches connecting various computer nodes and may be a router to which the switches are connected. Also we can see the Network Interface Card (NIC) at the back of the computer where we plug in the cable with the RJ45 connector‚ the blinking light etc. on the card. (Sometimes when it is not working

DesignIT has already relocated one Web Server (Microsoft IIS Server)‚ one File Server (Microsoft Server 2008)‚ and one more Server 2008 (Small Business Server). As a network design consultant‚ I have been charged with the task of designing and configuring the network for DesignIT. The small company has informed me that the network should include six computers‚ three printers‚ a Firewall‚ a wireless network for portable devices‚ and a high speed internet connection. DesignIT has also requested me
