CCDA DESGN 640-864: Designing Remote Connectivity

Chapter Description

This chapter discusses wide-area network technologies and design and includes sections covering Identifying WAN Technology Considerations, Designing the Enterprise WAN, and Designing the Enterprise Branch.


In this chapter, the following key points were covered on remote connectivity network design:

  • Analyze network requirements:
    • Type of applications, traffic volume, and traffic pattern
    • Redundancy and backup needed
  • Characterize the existing network and sites:
    • Technology used
    • Location of hosts, servers, terminals, and other end nodes
  • Develop WAN and branch network design:
    • Select WAN and branch technology to support requirements
    • Select hardware and software components to support requirements
  • Network application and connectivity requirements that influence the WAN design
  • The Cisco Enterprise MAN and WAN Architecture provides integrated QoS, network security, reliability, and manageability:
    • On private WANs
    • On ISP service through site-to-site and remote-access VPNs
    • On service provider–managed IPO or MPLS VPNs
  • The Cisco Enterprise Branch Architecture supports small, medium, large, and teleworker locations.
