Description

The Designing for Cisco Internetwork Solutions (DESGN) v3.0 is a 5-day instructor-led course that introduces the learners to the a structured and modular approach to designing networks that are scalable, resilient, and have well-defined failure domains. The content of this course discusses routing and switching design of Campus and Enterprise networks in detail. Data center, wireless networking, and real-time traffic infrastructure are introduced, and their effects on the core network are discussed from the design perspective.
The course enables learners to gather customer internetworking requirements, identify solutions, and design the network infrastructure to ensure basic functionality of the proposed network design.
