Description
This unit describes the performance outcomes, knowledge and skills required to secure and monitor the performance of a small to medium network.
It requires the ability to implement routing protocols, Access Lists (ACL’s) to block common security threats, implement Network Adress Translation (NAT) on an edge router and selecting a WAN technology for an organisation. The unit also includes using tools to monitor the network for performance as well as the application of systematic troubleshooting tools and techniques to ensure correct network operation and performance.
The unit applies to an Information Technology (IT) practitioner required to analyse, configure and troubleshoot routers and switches in small to medium sized business network.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
