Elements and Performance Criteria Pre-Content


Performance Criteria 

Elements describe the essential outcomes of a unit of competency.

Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

6.5 Troubleshoot basic WAN connection problems 

Required Skills and Knowledge

This section describes the skills and knowledge required for this unit.

Required skills 

  • communication skills to establish client requirements
  • problem-solving skills to troubleshoot and debug switch and router network issues
  • technical skills to assess and implement security requirements.

Required knowledge 

  • overview knowledge of:
  • classless routing protocols
  • WAN link protocols
  • detailed knowledge of:
  • basic routing concepts, small enterprise network switches and routers
  • classful routing protocols (RIPv1)
  • purpose and basic operation of the protocols in the open system interconnection (OSI) and TCP/IP models.

Evidence Guide

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:

  • design an IP addressing scheme to suit requirements
  • install, configure and test the network elements to ensure interoperability within the network
  • apply network topologies, protocols and security issues
  • apply solutions and troubleshoot defined network problems.

Context of and specific resources for assessment 

Assessment must ensure access to:

  • site where network installation may be conducted
  • small enterprise routers and switches
  • network design documentation
  • equipment specifications
  • hardware and software
  • organisational guidelines
  • computers
  • appropriate learning and assessment support when required.

Where applicable, physical resources should include equipment modified 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:

  • direct observation of the candidate installing, configuring and testing a new or updated network
  • evaluation of prepared documentation that outlines testing procedures, test results, recommendation to network changes and completion records
  • verbal or written questioning of required knowledge.

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 non-English 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.
