ICTTEN6042A
Undertake system administration

This unit describes the performance outcomes, skills and knowledge required to conduct system administration to maintain the integrity of network support systems and software.The unit applies to both system platforms and applications of computer systems including local area networks (LAN) and wide area networks (WAN).Computer-based networks such as call centres, billing centres, customer records, internet protocol (IP) based media content managers for internet protocol TV (IPTV) and web sites all require efficient system administration to maintain a viable network. System administration involves proactive maintenance, providing application support, creating and deleting user accounts and special investigations.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.

Application

System administration support officers from service providers and large organisations apply the skills and knowledge in this unit to manage and administer the network and make recommendations for improved customer support.

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 ability to:

provide methodology for system maintenance

produce cost benefit analysis and training for database optimisation and administration

conduct system measurements

develop support processes for system users

manage user accounts and security procedures

investigate potential system administration problems and make recommendations.

Context of and specific resources for assessment

Assessment must ensure:

a network for maintenance and analysis of special investigations

equipment and systems manuals, specifications and enterprise policy.

Method of assessment

The following assessment method is appropriate for this unit:

direct observation of the candidate undertaking system measurements and investigations

direct observation of the candidate providing application support, and creating and deleting user accounts

review of reports and recommendations completed by the candidate for special investigations

oral or written questioning to assess knowledge required to prepare methodology for system maintenance.

Guidance information for assessment

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

ICTNPL6046A Undertake network performance analysis

ICTTEN6043A Undertake network traffic management

ICTTEN6044A Coordinate fault rectification and restoration of service following network outages

ICTTEN6045A Implement planned network changes with minimal impact to the customer.

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.
