Build and maintain a secure network


Application

This unit describes the skills and knowledge required to build a simple and secure wired local area network (LAN) or wide area network (WAN) using a range of client server applications and services.

It applies to individuals who may work in job roles such as an installer of internet protocol (IP) networks, a WAN and LAN network technician or a WAN and LAN network support person.

No licensing, legislative or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

ELEMENT

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Prepare to build LAN or WAN

1.1 Prepare for given work confirming site-specific work health and safety (WHS) and environmental requirements, with appropriate personnel

1.2 Identify safety hazards and implement risk control measures in consultation with appropriate personnel

1.3 Determine network design specification from job briefs or appropriate personnel

1.4 Determine network addressing scheme for network connectivity and confirm using calculations

1.5 Select and obtain network hardware according to established procedures

1.6 Obtain operating instructions, manuals, hardware and software testing methodologies

1.7 Consult appropriate personnel to ensure the task is coordinated effectively with others involved at the worksite

2. Build and verify network

2.1 Establish connections between network hardware according to manufacturer’s specifications and established procedures

2.2 Verify network routing and switching to conform to network design specification

2.3 Set up, configure and share network resources between network devices

3. Monitor network performance and troubleshoot network

3.1 Monitor network traffic and assess performance metrics against manufacturer’s specifications and established procedures

3.2 Identify security threats and initiate control measures according to enterprise procedures

3.3 Troubleshoot network and internet connectivity according to manufacturer’s specifications and enterprise procedures

4. Complete and document network build

4.1 Restore worksite to safe condition according to established safety procedures

4.2 Record and store network schematics and network addressing scheme

4.3 Notify appropriate personnel of completion of the task

4.4 Notify customer and obtain sign-off

Evidence of Performance

Evidence of ability to:

effectively implement work health and safety (WHS) workplace procedures and practices

develop a network addressing scheme

determine required network components to build the network

plan, build, configure, test and analyse performance of a network

troubleshoot network problems.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.


Evidence of Knowledge

To complete the unit requirements safely and effectively, the individual must:

describe enterprise WHS procedures

explain internet and computer network communication

outline network addressing schemes including open systems interconnect (OSI) and transmission control protocol (TCP)/IP model

describe planning the cabling of ethernet networks

define the seven layer OSI model

identify correct tool and equipment usage

identify troubleshooting procedures.


Assessment Conditions

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications network engineering field of work and include access to:

a site where building and maintenance of secure network may be conducted

tools, equipment and materials currently used in industry

relevant workplace procedures

product and manufacturing specifications and reference material.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
