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: analyse, document and troubleshoot a given complex network using industry methodologies and resources develop monitoring and management plans use networking and network fault management tools evaluate risk assessments and minimise threats on enterprise networks.
Context of and specific resources for assessment	Assessment must ensure access to: location where the network configuration can be implemented routers and switches with appropriate operating systems computers suitable testing and analyses tools 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: direct observation of the candidate preparing, installing, configuring, testing, analysing and correcting network problems documentation of the tools and methodologies adopted by the candidate to test, analyse, network functionality and performance (system audits) documentation of the options and justification for the selected solutions developed to address network problems evidence of the success of the corrective measures delivery of the revised configuration documentation of the entire network verbal and 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.
