CCNA-TS - Troubleshooting Cisco Internetworks for Network Associates

Classroom Learning

Also available via

Who Needs to Attend

Individuals seeking CCNA certification; network engineers requiring troubleshooting skills on Cisco devices and networks; CCNP candidates wishing preparation for the TSHOOT course; and any network professional responsible for the availability and performance of the enterprise network

Prerequisites

Follow-On Courses

Develop in-demand skills necessary to troubleshoot a medium-to-large network of Cisco routers and switches.

In this intensive 3-day Mini Camp, you will identify a process for developing the network baseline for routers, switches, and end systems, and you will develop a working understanding of proven troubleshooting methodologies based on Cisco best practices, industry-proven processes, and the instructor's practical experiences. The focus of the course is on general routing and switching at the Cisco Certified Network Associate (CCNA) level of expertise. Numerous practical troubleshooting lab exercises reinforce the lecture material. In fact, for each hour of lecture, there is an hour of lab. Each student pair will have access to seven Cisco devices (routers and switches) in order to complete the lab scenarios.

If you require the skills to troubleshoot a medium-to-large Ethernet-TCP/IP network using Cisco routers and switches and you would like to better prepare for the troubleshooting portion of the CCNA certification exam, this is the course for you.

Mini Camp Hours

Class begins each day at 8:00 AM and may extend until 8:00 PM or later. Students should expect class to run late into the evening on most days. In a typical Mini Camp, it is not uncommon for some students to remain past 8:00 PM, depending upon the class size and the experience of the students.
