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

develop basic security functionality for either VPN LANs WANs or WLANs

implement such security

maintain such security

document the security implemented and its maintenance

Context of and specific resources for assessment

Assessment must ensure access to

network technical requirements

network infrastructure including servers and security hardware and software

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

security protocols

review of candidates documentation of installed security and its maintenance

evaluation of candidates security implementation on a VPN

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
