Interconnecting Cisco Networking Devices (CCENT), Part 2 of 4: Internet Connectivity

Course description

Interconnecting Cisco Networking Devices Part 1 is the exam associated with the Cisco Certified Entry Network Technician (CCENT) certification or the first half of the Cisco Certified Network Associate Routing and Switching (CCNA Routing and Switching). This course is about establishing internet connectivity. Topics covered include: understanding internet layers and protocols, IP addressing, broadcast domains, relaying packets, use of the Cisco discovery protocol, static routing, access control lists and traffic handling as well as using network address translation.

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.
