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 and configure a routed network

configure a VLAN on a given network topology

configure VLAN trunking and spanning tree protocols

establish VLANs over a wireless network

design and deploy remote access and network security.

Context of, and specific resources for assessment

Assessment must ensure:

a site where configuring advanced network switching may be conducted

use of tools, equipment and materials currently used in industry

relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials.

Methods 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 performing network switch configuration

direct observation of the candidate troubleshooting network problems

oral or written questioning to assess required knowledge.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example with:

ICTTEN2209A Build and maintain a secure network

ICTTEN4212A Apply advanced routing protocols to network design

ICTTEN4214A Install and maintain a wide area network.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
