Designing Cisco Network Service Architectures (ARCH) course enable students to perform the conceptual, intermediate, and detailed design of a network infrastructure that supports desired network solutions over intelligent network services, to achieve effective performance, scalability, and availability. ARCH enables learners, applying solid Cisco network solution models and recommended design practices, to provide viable, stable enterprise internetworking solutions. The course presents concepts and examples necessary to design converged enterprise networks. New is the addition of a content addressing software defined networks (SDN). Building on the Designing for Cisco Internetwork Solutions (DESGN) course, in the ARCH course the students will learn additional aspects of modular campus design, advanced addressing and routing designs, WAN service designs, enterprise data center, and security designs.
