Beskrivelse

This intensive extended 3-day course is focused on general routing and switching challenges at the Cisco Certified Network Associate (CCNA) level of expertise. Delegates will identify a process for developing a network benchmark for routers, switches, and end systems, as well as gain a working understanding of proven troubleshooting methodologies based on Cisco best practices, industry-proven processes, and the instructor's practical experiences. Numerous practical troubleshooting lab exercises reinforce the lecture material with the time dedicated to labs and lectures evenly split. Each student pair will have access to seven Cisco devices (routers and switches) in order to complete the lab scenarios.

Mini Camp Hours

Delegates should expect to start classes early and finish late and may extend to 8:00 PM or later.

Forudsætninger

Attendees should meet the following prerequisites:

ICND1 - Interconnecting Cisco Network Devices 1
