Investigate the application of cloud networks in telecommunications switching

Assessment tool

Version 1.0
Issue Date: May 2024


Telecommunication planning engineers and senior technical staff apply the skills and knowledge in this unit to investigate the application of cloud networks (infrastructure-as-a-service) in telecommunications switching.

Technical planners develop strategies to accommodate shortfalls in capacity and functionality for a switching network, and develop solutions for network growth using emerging technologies.

This unit describes the performance outcomes, skills and knowledge required to investigate the application of cloud networks (infrastructure-as-a-service) in telecommunications switching.

Most infrastructure-based services are embedded in physical infrastructure. Cloud computing and infrastructure-as-a-service changes the focus from the physical infrastructure to the new world of virtual infrastructure. No longer are services built around floor space, servers or ports, but rather around virtual machine (VM) images, application instances, and virtualised storage and networks.

Scalability, cost savings, security, flexibility of infrastructure and energy consumption are significant factors when business considers cloud networks. Applications involving cloud networks are developed to support business strategies.

Cloud network solutions support the application of Next Generation Technologies (NGN).

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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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:

evaluate the current physical network infrastructure's capacity and functionality shortfalls

investigate the application of cloud networks and plan the architectural design

develop components of cloud networking solution for meeting capacity and functionality requirements of the network

assess the risks in using cloud networks to meet capacity and functionality requirements of the network

analyse impact of integration of cloud network solution on the network

prepare a test plan with test scenario and produce a test management schedule

use integration document and software test management tools to replicate issues exhibited in test environment

certify cloud network solution compatibility and compliance

prepare a cost-benefit analysis of the cloud network solution

develop a business case for implementation of a cloud network.

Context of and specific resources for assessment

Assessment must ensure:

site where the application of cloud networks in telecommunications switching may be investigated

software tools currently used in industry

vendor products, specifications, equipment and enterprise policy required for the activity.

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 investigating the application of cloud networks and planning the architectural design

review of reports, plans and business case for a cloud network solution prepared by the candidate

oral or written questioning of the candidate to assess knowledge of cloud networks.

Guidance information for assessment

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

ICTTEN8197A Produce engineering solutions using numerical computations and simulation.

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.

Submission Requirements

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
