Interconnecting Cisco Networking Devices (CCNA), Part 1 of 5: Scalable Networks

Course description

The Interconnecting Cisco Networking Devices Part 2 (ICND2) is the exam associated with the Cisco Certified Network Associate certification. This course starts with making sure you understand how VLAN's work. Next, it covers layer 2 networking as well as redundant paths and spanning trees It finishes up by looking at redundancy at layer 3 with routers as well as HSRP and gateway load balancing.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This is part 1 in the series.
