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 select and install a router using predetermined configuration and tests. Basic configuration capability is essential in demonstrating competency. To demonstrate competency in this unit the person will require access to: Router specifications Technical requirements for a network Router Cabling Networked (LAN) computers WAN service point of presence (or simulated) |
Context of and specific resources for assessment | A router connects networks together, controlling the routing of packets from source to destination and providing alternate paths when necessary. Routers are more sophisticated than bridges, connecting networks of different types and making logical routing decisions on the basis of available data. Typically a router hands off packets to another router along the path until the destination is reached. In the context of the Internet, a router is a device or, in some cases, software in a computer, that directs information packets to the next point toward their destination. A router is located at any juncture of networks, including each Internet point-of-presence. As such, routers are key to the operation of the Internet. It is essential that this unit covers a broad variety routers ranging from simple SOHO ADSL/CABLE routers, to complex fibre channel multi-routing units designed for backbone capability. Additionally, it is imperative that routers are provided for hands-on experience, particularly SOHO and Fibre channel routers. The breadth, depth and complexity of knowledge and skills in this competency would cover a broad range of varied activities or application in a wider variety of contexts most of which are complex and non-routine. Leadership and guidance would be involved when organising activities of self and others as well as contributing to technical solutions of a non-routine or contingency nature. Assessment must ensure: Performance of a broad range of skilled applications including the requirement to evaluate and analyse current practices, develop new criteria and procedures for performing current practices and provision of some leadership and guidance to others in the application and planning of the skills would be characteristic. Applications may involve responsibility for, and limited organisation of, others. |
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. The assessment of this unit of competency will usually include observation of router selection and configuration for a variety of scenarios 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, for example: ICAA4047B Determine project specifications and secure client agreement An individual demonstrating this competency would be able to: Demonstrate understanding of a broad knowledge base incorporating some theoretical concepts Apply solutions to a defined range of unpredictable problems Identify and apply skill and knowledge areas to a wide variety of contexts, with depth in some areas Identify, analyse and evaluate information from a variety of sources Take responsibility for own outputs in relation to specified quality standards Take limited responsibility for the quantity and quality of the output of others Maintain knowledge of industry products and services Additionally, an individual demonstrating this competency would be able to: Configure and debug routers and routing tables Select a router for a particular task Interpret available information and request clarification where needed Take responsibility for outputs in work and learning |
