Industry Projects

Our projects are designed by experts in the industry to reflect industry standards. By working through our projects, Learners will gain a practical understanding of what they will take on at a larger-scale in the industry. In total, there are 5 Projects that are available in this program.

Peer-to-Peer Communication

In this project, the learners will use Cisco Packet Tracer and understand communication flow from peer to peer. For this project, learners will work in real-time and simulation mode.

In real-time mode, learners will have to configure the cross-over cable for the same devices and configure the straight-through cable for two different devices
In basic peer-to-peer communication, they will have to connect the same devices through ethernet
The valid IP for peer-to-peer connectivity has to be configured as well.
The connectivity existing between two devices has to be checked through the command prompt window
In simulation mode, a PDU Packet has to be added to one device, and the simulation has to be run.

Local Area Network with Hub

In this project, learners will understand what a local area network with a hub is, and how it works using Cisco Packet Tracer. Learners will have to:

Configure the hub using a set of devices with straight through cable
Configure a valid IP address to all the devices
Check the connectivity existing between the devices in the command prompt window
In simulation mode, add a sample PDU Packet to one device and run the simulation

Local Area Network with Switch

Learners will understand what a local area network with switch lab is, and how it works when used in LAN using Cisco Packet Tracer. This project requires performing the following:

Configuring the switch using a set of devices with straight through cable
Configuring the valid IP address on all the devices
Checking the connectivity existing between the selected two devices in the command prompt window
In simulation mode, add a sample PDU Packet to one device and run the simulation between selected devices to check the connectivity

Communication between Hosts in Two Different Local Networks

Learners will understand how communication happens between hosts in different local area networks using Cisco Packet Tracer. This project requires the following actions:

To configure devices to the switch in two LAN Networks with a straight-through cable
To configure a valid IP address for each LAB with each subnet mask
To enable the communication between two LAN networks by using a router
To check the connectivity between two networks using a router through the default gateway
In simulation mode, add a sample PDU Packet to one device in a network and run the simulation between the selected devices of another network to check the connectivity.

Inter-Vlan Communication

Learners will understand the logic underlying inter-VLAN communication, and replicate the same using the Cisco Packet Tracer. This project requires the following:

To create an interconnected VLAN model with switches, routers, and PCs.
To assign IP addresses to each PC and configure the router.
