Course Outline

In this course, networking professionals who work in complex network environments will gain the skills needed to maintain their networks and to diagnose and resolve network problems quickly and effectively. You will learn to troubleshoot and maintain particular technologies, and you will learn procedural and organizational aspects of the troubleshooting and maintenance process. A large part of the course consists of practicing these skills and reinforcing the concepts by putting them to use in a controlled environment.
At the end of the course, you will have increased your skill level and developed a set of best practices that are based on your experience and the experiences of other students and that you can take back to your organization. This course is a component of the CCNP curriculum and assists the network professional in preparing for Cisco CCNP certification.

- do we get a certifiacate for completing the courseÉ - although the instructor did give us excercises to do I would have liked a few more - almost like a test, so that I made sure I retained and understood what was taught. I`m a learn to do by doing person and like the instrutor lead courses so I can have someone there to explain in my terms how things work. I`ll have to really use the online excercises to make sure Ì am confident when I need to do something in Excel.

The instructor was excellent as was the hands-on learning approach. The only thing I took issue with was the fact that there were a lot of bilingual persons taking the course and they tended to ask questions in French, during this English class. The instructor was trying very hard to explain everything in both languages, but I felt that these students should have requested a French-speaking classroom setting if they wanted to speak French.

For the cost of this course, a hard copy of the course handout should be provided as the classes follows the handout word for word.

The course was very relevant. I was able to apply the knowledge I aquired in the course to my job on the very next day. The only complaint I have is with the temperature of the room. It was freezing! Students has to wear a jacket or sweater. We were told the temp gage was shared with another classroom that was quite warm so they had turned the temp very low causing our room to be very uncomfortable.

Given the cost of the course, the hardcopy of the manual should have been provided. It would have been useful to make notes alongside the material as we went along.

Reviewed by Jeff P. 2011

   

I am very disappointed with the handouts. I was told I could go online and download a copy of the manual, the problem is that I would like the printed copy of the manual. I chatted online with one of your technitian who was unable to help me. Then I was told someone would contact me by phone to help me. That never happened. When taking a training course, a person EXPECTS to leave the course with ALL the material.
