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 following is essential:
Assessment must confirm the ability to develop, implement and maintain a network security shield for VPNs, LANs and WLANs.
To demonstrate competency in this unit the following resources will be needed:
Network technical requirements
Network infrastructure, including servers and security hardware and software
Industry/vendor training may include CISCO, Microsoft, IBM, Redhat.
Context of and specific resources for assessment
The breadth, depth and complexity covering planning and initiation of alternative approaches to skills or knowledge applications across a broad range of technical and/or management requirements, evaluation and coordination would be characteristic.
The demonstration of competency may also require self-directed application of knowledge and skills, with substantial depth in some areas where judgement is required in planning and selecting appropriate equipment, services and techniques for self and others.
Assessment must ensure:
Applications involve participation in development of strategic initiatives as well as personal responsibility and autonomy in performing complex technical operations or organising others. It may include participation in teams including teams concerned with planning and evaluation functions. Group or team coordination may also be involved.
Method of assessment
The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1.
Competency in this unit should to be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency.
Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process.
Guidance information for assessment
The interdependence of units for assessment purposes may vary with the particular project or scenario. Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICAA5056B Prepare disaster recovery and contingency plans
An individual demonstrating this competency would be able to:
Demonstrate understanding of a broad knowledge base incorporating theoretical concepts, with substantial depth in some areas
Analyse and plan approaches to technical problems or management requirements
Transfer and apply theoretical concepts and/or technical or creative skills to a range of situations
Evaluate information, using it to forecast for planning or research purposes
Take responsibility for own outputs in relation to broad quantity and quality parameters
Take some responsibility for the achievement of group outcomes
Maintain knowledge of industry products and services
