Elements and Performance Criteria

1. Determine user needs
   • Identify the different segments of the proposed network based on business requirements
   • Determine segment needs, using network functional analysis
   • Estimate traffic content and volumes based on business requirements
   • Develop a prioritised organisational network functional matrix
2. Develop local area network specification
   • Determine the resource requirements for each network segment on the basis of functional analysis
   • Analyse features of the physical environment for the effect on network design
   • Conduct a costing process for possible topology options
   • Consider topology options with reference to available resources and network functional matrix
   • Select and document appropriate network topology based on business requirements and functional analysis

Performance Evidence

Evidence of the ability to:

analyse business or organisational needs

identify the most appropriate local area network (LAN), virtual private network (VPN) or wireless local area network (WLAN) topology

document recommendations.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
