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:

plan and design a MPLS network that meets business requirements

configure and test the MPLS network according to specified guidelines

produce appropriate documentation

implement secure VPN tunnelling.

Context of and specific resources for assessment

Assessment must ensure:

a live network and networked computers

network design documentation, equipment specifications and organisational guidelines

network components, routers, switches and multi-layer switches.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct observation of the candidate planning, designing and configuring a MPLS

review of documentation completed by the candidate

oral or written questioning of the candidate to assess required knowledge and skills.

Guidance information for assessment

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

ICTTEN6216A Design and manage internet protocol TV in a service provider network.

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.

Required skills

analytical skills to use complex technical data to develop network designs

communication skills to consult with customers

literacy skills to read and write reports

numeracy skills to use binary systems

project planning skills to set benchmarks and identify scope

problem solving skills to solve a range of predictable network problems

research skills to identify, analyse and evaluate broad features of a particular business domain and best practice in networking technologies including hardware and software to be installed

technical skills to:

deploy multipoint-to-multipoint VPLS domains via IP-MPLS cloud

implement and verify routing information protocol (RIP), enhanced interior gateway routing protocol (EIGRP), open shortest path first (OSPF) and border gateway protocol (BGP) operations

implement MPLS architecture across a WAN environment

implement secure VPN tunnels across the MPLS network

Required knowledge

current industry-accepted hardware and software products

network operating systems and cabling standards

networking technologies

the customer business, domain, function and organisation effect on customer requirements and network equipment

transmission technologies and protocols
