Elements and Performance Criteria

1. Define network
   • 1.1 Identify current and future network requirements based on the organisation's business and technical requirements
   • Design an appropriate structure to meet client requirements, such as video, audio or data application services
   • Design a network addressing system with subnet and host identities (IP addressing) and virtual LANs (VLANs)
   • Identify and document resource requirements according to network design
2. Install and configure network backbone
   • Install and configure switches and routers according to network requirements and resources
   • Install network protocol suites using configurations on switch uplink ports as required by network design specifications
   • Configure hosts and workstations for network access
3. Test and validate network
   • Test network connectivity to ensure operation parameters are met between hosts on segments or VLANs
   • Make adjustments as required
   • Validate and document network performance

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Evidence of the ability to build an ATM LAN that provides the required services and communication standards document resource requirements and network performance
Context of and specific resources for assessment	Assessment must ensure access to local area network infrastructure switches with various interfaces fast one gigabit ethernet appropriate learning and assessment support when required modified equipment for people with special needs
Method of assessment	A range of assessment methods should be used to assess practical skills and knowledge The following examples are appropriate for this unit verbal or written questioning to assess candidates knowledge of network hardware LAN and WAN topologies VLANs TCPIP internet protocol version IPv internet protocol version IPv review of completed documentation of a networks performance direct observation of candidate installing and testing backbone technology
Guidance information for assessment	Holistic assessment with other units relevant to the industry sector workplace and job role is recommended where appropriate Assessment processes and techniques must be culturally appropriate and suitable to the communication skill level language literacy and numeracy capacity of the candidate and the work being performed Indigenous people and other people from a nonEnglish speaking background may need additional support In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Network may include:	data large and small LANs private lines use of the PSTN for dial-up modems only voice VPNs.
Technical requirements may relate to:	business database network people in the organisation platform system.
Client may include:	external organisations individuals internal departments internal employees.
Network protocol suites may include:	IPv6 (layer 3 protocol only) TCP/IP (IPX/SPX, DECnet, AppleTalk are legacy protocols).
