Troubleshooting and Maintaining Cisco IP Networks


The course is designed to teach professionals who work in complex network environments the skills that they need to maintain their networks and to diagnose and resolve network problems quickly and efficiently. The course will provide information about troubleshooting and maintaining particular technologies as well as procedural and organizational aspects of the troubleshooting and maintenance process. A large part of the training will consist of practicing these skills and reinforcing the concepts by putting them to use in a controlled environment. At the end of the course, the students will have increased their skill level and developed a set of best practices that are based on their own experience and the experiences of other students and that they can take back to their organizations.

The authorized student material, that each Global Technology Training (GTT) student receives, includes more than nine hours of e-learning content that stresses core learning objectives covered in the associated certification exam. These self-paced lessons, demos, and assessments can be absorbed by candidates after the class and at their own pace.
