Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

WLANs

identify and describe the typical components and technologies required for a WAN, including:

concepts and types of modems

internet protocol (IP) addressing

packet switching

routed or routable protocols, including IP, IPX and AppleTalk

router operations, including double data rate (DDR)

routing protocols, including routing information protocol (RIP), enhanced interior gateway routing protocol (EIGRP) and open shortest path first (OSPF)

transmission control protocols or internet protocols (TCPs/IPs)
