Designing for Cisco Internetwork Solutions 3 (DESGN)

This instructor-led course is designed to provide students with the knowledge and skills required to achieve associate level competency in network design. This is a structured and modular approach to designing networks that are scalable and resilient with well-defined failure domains. The course discusses routing and switching, the 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.


Target Audience

This course is intended for pre-sales and post-sales network engineers involved in network design, planning and implementation. As well as individuals looking to attain the Cisco Certified Design Associate (CCDA) certification or the Cisco Certified Design Professional (CCDP) certification.


Objectives

After you complete this course you will be able to:

  • Describe and apply network design methodologies
  • Describe and apply network design concepts of modularity and hierarchy
  • Design a resilient and scalable Campus network
  • Design a resilient and scalable connectivity between parts of your Enterprise network
  • Design connectivity to the Internet and internal routing for your network
  • Integrate collaboration and wireless infrastructure into your core network
  • Create scalable IPv4 and IPv6 addressing
  • Describe what are software defined networks and describe example solutions


Prerequisites

It is strongly recommended, but not required, that students have the following knowledge and skills:

  • A Cisco CCNA Routing and Switching certification and practical experience with deploying and operating networks based on Cisco network devices and Cisco IOS software
  • Implementing Cisco Wireless Network Fundamentals (WIFUND) level knowledge of wireless topics
  • Complete the Implementing Cisco IP Switched Networks (SWITCH) course
