Required Skills and Knowledge

REQUIRED SKILLS AND KNOWLEDGE
This section describes the skills and knowledge required for this unit.
Required skills
Communication skills in relation to dealing with clients and team members (e.g. when internet specifications are produced to meet client user requirements and budget constraints) Basic report writing skills for business, including analysis and evaluation Ability to create and use logs for examining and reporting, required to manage and support the internet service on the organisation's LAN Problem solving skills involving participation of other users and management. Basic research skills for identifying, analysing and evaluating broad features of a particular business and sound skills in internet security patching and monitoring Questioning and active listening skills in relation to clients and team members Ability to participate in project planning activities, in relation to scope, time, cost, quality, communications and risk management
Required knowledge
Current and developing industry hardware and software (e.g. routers, servers, switches and modems), with broad knowledge of general features and capabilities (e.g. LAN or WAN application, network traffic management) General knowledge of the organisation's business needs and functions General understanding of LAN-based communications technologies Knowledge of internet (WAN-based) technologies, with general understanding of features and capabilities, incorporating depth in some areas, for example, being able to consider the various WAN technologies when managing and supporting the internet (e.g. ADSL, ISDN, PRI (primary rate interface) and BRI (basic rate interface), ATM, frame relay, leased line) General knowledge of OH&S requirements in relation to working in a safe manner; environmental aspects of work that is undertaken and basic and ergonomic considerations relating in particular to the workstation environment Security knowledge, with broad understanding of general features and capabilities, with limited depth in some areas (e.g. when monitoring security and internet access Broad knowledge of vendor product and vendor directions (e.g. when installing and configuring internet infrastructure to meet business requirements (e.g. current trends are self-configuring ADSL or cable modem-router-switches, however, these apply to the simpler LANs, such as SOHO (Small Office, Home Office), where LAN configurations are relatively simple) Broad knowledge of open source options and software (e.g. Linux-based systems) as well as proprietary software (e.g. Microsoft based systems)

Evidence Guide

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 verify knowledge of internet technologies and that internet technology (both hardware and software) is installed and configured correctly. To demonstrate competency in this unit the person will require access to: Server hardware and software Security policy guidelines Networking hardware (e.g. switches, cables)
Context of and specific resources for assessment	The choice of LAN/WAN technologies has increased notably in recent years. Two important aspects accompany these many alternatives: the affordable cost and the emerging trend to automated set-up predominantly for the home or small business market. This unit is geared for medium to large LAN/WAN designs rather than the automatic set-up approach and accordingly requires a more rigorous level of configuration. 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. Assessment must ensure: 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. 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 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. 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. 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
