Elements and Performance Criteria

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.
Resources may include availability of:
central processing unit (CPU) cores
CPU load to be shared
CPU speed
hard disk space (storage)
memory (RAM)
network bandwidth
physical CPUs.
Enterprise requirements may include:
how and what the enterprise wants regarding work environment
preventative maintenance and diagnostic policy
problem-solving processes
roles and technical responsibilities in network management
vendor and product service level support agreements.
Functionality may include:
availability of services on a virtual machine
virtualised services performing the same as a service running on physical machine.
Migration tools may include:
AutoVirt AutoMove
Leostream
Microsoft System Center Virtual Machine Manager (SCVMM)
Microsoft Virtual Server 2005 Migration Toolkit
PlateSpin Migrate
Virtuozzo
Vizioncore vConverter
VMware Converter
VMware P2V Converter
VMware vCenter Converter.
Physical machine may include:
laptop or notebook
server
workstation.
Installation media may include:
blu-ray disk
CD
DVD
floppy disk
ISO image
network share
universal serial bus (USB) flash drive.
Snapshots may include:
stored virtual machine configuration to allow:
rollback of changes to a virtual machine
implementation of instant changes to a virtual machine.
High availability may relate to use of:
clustered virtual machines performing an identical task
load balancing between virtual machines to ensure service requirements are met
pre-configured virtual machines that can be rapidly stored and deployed in the event of a system failure
standby power solutions in the event of a power disruption.

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:
monitor and provide resources to virtual environment
create and deploy virtual machines
implement changes to virtual machines
back up and recover a virtual machine.
Context of and specific resources for assessment
Assessment must ensure access to:
site or prototype where virtual machine environments may be implemented
network technical requirements
appropriate software
appropriate learning and assessment support when required.
Where applicable, physical resources should include equipment modified for people with special needs.
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:
verbal or written questioning to assess candidate’s knowledge of emerging policies relating to:
current recommendations on sustainability options in ICT design
benefits of virtualisation
installation and configuration of virtualisation software
installation and configuration of virtual machines
configuration of virtual machines into network design
direct observation of candidate demonstrating:
installation and configuration of virtualisation software
installation and configuration of virtual machines
configuration of virtual machines into network design
review of documentation prepared by candidate to:
record the process of installing and configuring virtual machines
document the system.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.
Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.
Indigenous people and other people from a non-English speaking background may need additional support.
In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.
