General knowledge so that the learner can define the requirements covering areas such as

Scope of operation redundancy paths highlowspeed links protocols security traffic flow patterns traffic load response time and reliability requirements types of usersapplications growth projections and capacity planning constraints and costs

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 following is essential

Assessment must confirm the ability to clearly identify the configuration for connecting a LANWLAN or VPN into a WAN given budget constraints and business needs

To demonstrate competency in this unit the learner will need access to

Design documents relating to LANs to be incorporated in the WAN

Equipment specifications

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 andor management requirements evaluation and coordination would be characteristic

Assessment must ensure

selfdirected 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

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 ICA Section

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 andor 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 The interdependence of units for assessment purposes may vary with the particular project or scenario

Guidance information for assessment

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

ICAAB Determine bestfit topology for a local network

ICAA5144B Determine best-fit topology for a local network

ICAAB Gather data to identify business requirements

ICAA5151B Gather data to identify business requirements

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 andor 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
