ICND1 - Interconnecting Cisco Networking Devices, Part 1

ICND1 - Interconnecting Cisco Networking Devices, Part 1

Gain a foundational understanding of core routing and switching technologies and prepare for the CCENT certification exam (100-105 ICND1).


In this course, you will learn how to install, operate, configure, and verify a basic IPv4 and IPv6 network, including configuring a LAN switch, configuring an IP router, managing network devices, and identifying basic security threats. The goal of the course is to provide you with the knowledge and skills necessary to install, configure, and operate a small- to medium-sized network.

Now at version 3.0, Interconnecting Cisco Networking Devices, Part 1 (ICND1) v3.0 provides the foundational understanding of network Layers 1 through 3 that are applicable to core routing and switching plus other advanced technologies. Several topics have been added including; understanding the interactions and network functions of firewalls, wireless controllers and access points, along with additional focus on IPv6 and basic network security.

Interconnecting Cisco Networking Devices, Part 2 (ICND2) v3.0, which covers topics in more depth and teaches you how to perform basic troubleshooting steps in enterprise branch office networks, preparing learners for the CCNA Routing and Switching certification, can follow this course.
