Build a strong foundation in enterprise network architecture and virtualization technologies. This course introduces core design models, redundancy strategies, and essential virtualization concepts for modern enterprise environments.

Learners will explore the fundamentals of enterprise network design, including tiered architectures, on-premise versus cloud solutions, and redundancy mechanisms. The course also covers software-defined networking approaches such as SD-WAN and SD-Access, as well as key virtualization technologies like hypervisors, virtual machines, VRF, GRE/IPsec tunneling, LISP, and VXLAN. By the end of this course, learners will understand how to design resilient networks and implement virtualization solutions that support scalable and flexible enterprise infrastructures. This course blends clear theoretical explanations with practical demonstrations to help learners grasp both traditional and modern enterprise networking concepts. Learners progress through structured modules that build foundational knowledge and prepare them for advanced topics in enterprise networking. This course is part one of a three-course Specialization designed to build a complete and cohesive understanding of the subject. While it offers valuable skills on its own, you'll gain the most benefit by progressing through all three courses as a structured learning journey.
