Description
This unit describes the performance outcomes, knowledge and skills to investigate design concepts of an accessible and secure network suitable for a small to medium size enterprise (SME).
It requires the ability to investigate the features and operations of a Wireless Local Area Network (WLAN) and includes network security requirements, network design features, virtualisation concepts and network automation concepts. The unit also covers the use of systematic troubleshooting tools and techniques to ensure correct network operation and performance.
The unit applies to an Information Technology (IT) practitioner required to oversee the operation of a small to medium sized business network.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
