This course, in which hands-on work plays a central role, will enable you to understand and implement the essential elements of enterprise computer networks. All genuinely important aspects will be covered, particularly the features and implementation of interconnection equipment, with emphasis on routers, TCP/IP, and top-level protocols like DNS, DHCP, HTTP, etc. You’ll be able to validate your skills with AVIT® certification, offered as an option.

Introduction to network management
The exercises and demonstrations in this course are based on the end-to-end construction of a mini enterprise network based on the traditional HQ/branch model. Participants will configure and interconnect servers, workstations, and equipment as the course goes on.
Customer reviews are based on end-of-course evaluations. The score is calculated from all evaluations within the past year. Only reviews with a textual comment are displayed.
