Introduction The CompTIA Network+ proves knowledge of networking features and functions and is the leading vendor-neutral certification for networking professionals. This course provides delegates with the knowledge and skills necessary to manage, maintain, troubleshoot, install, operate, and configure basic network infrastructure, describe networking technologies and basic design principles; adhere to wiring standards and use the testing tools. The CompTIA Network+ is the first step in starting a networking career and is recognised by many vendors such as Microsoft, Cisco, Novell and Red Hat as part of their certification tracks.

Prerequisites Before attending this course, delegates must have: Attended the CompTIA A+ course or have; 18 to 24 months of experience in the networking field

Target Audience Anyone wishing to build a solid foundation with regard to networking technology Anyone wishing to pursue a career in IT networking Network administrators, network technicians, network installers, help desk technicians, cable installers.
