CCNA4. Design and support of computer networks

The goal of this course is to help develop the skills required to design small corporate LANs and WANs. The course is a short tutorial on gathering information about customer requirements, choosing equipment and protocols based on those requirements, and creating a network topology to meet customer needs. Issues related to the creation and implementation of the proposed project for the client are also considered. The course aims to develop the practical skills required to work as Presales and Entry-Level Networking Professionals.

Upon completion of this course, you will receive information on the following topics: cisco wireless certified

the goal of proper network design;

Using the Cisco Network Lifecycle Method in Design;

methods of describing existing networks to prepare for their modernization;

the impact of various applications and services on network design;

requirements for the design of the central level, distribution and access levels for the enterprise complex, including wireless access and security;

design requirements for WAN connections at the enterprise edge and VPN support for remote workers;

testing and verification of the design of the network of the enterprise campus and the global network;

preparation and presentation to the client of a commercial proposal for network modernization.
