Interconnecting Cisco Networking Devices Part 1 focuses on providing the skills and knowledge necessary to implement and support a small switched and routed network. For the purpose of this course, a small network is defined as 1 to 20 hosts connected to a single switch, with the switch running a single VLAN (VLAN1). The switch is also connected to a router providing a routed link (Routing Information Protocol [RIP] and default) to a simulated Internet and corporate office. ICND1 works from the bottom up, providing knowledge and skills as they are needed. The course starts with an introduction to networks. It then introduces host-to-host communications using TCP / IP. Next, Layer 2 devices (switches) are introduced into the network. Next, Layer 3 devices (routers) are introduced into the network. The introduction of Layer 3 devices leads to the use of WANs and routing to connect the site to the Internet and corporate sites.
Cisco Systems offers CCENT, which delves deep into networking, specifically focusing on Cisco's hardware and software. The course covers everything from the basics of routing and switching, installation, operation, and troubleshooting network devices. You must pass the Interconnecting Cisco Networking Devices Part 1 or ICND1 exam to earn the CCENT certification. Having this certification on your resume will give you a leg up on the competition. 781b155fdc
