I've completed by Microsoft Professional and Server Exams and am now studying for my CCNA.
However, I haven;t got a clue about Novell or IPX. Can someone explain what SAP and GNS are?

I suck at IPX, so someone is likely to give a better explanation than me, but here goes anyway.

SAP - Service Advertisement Protocol. These are how IPX devices announce what services they contain. Print queues are a service. File sharing is a service. NDS is a service, etc.

GNS - Get Nearest Service. IPX is server-centric so clients rely on servers to tell them what services are available on a network. When a client requests a service (or is it when it starts up) it issues a GNS request to find a server and then queries it to determine what services are available. This factors into the Cisco world because routers build SAP tables just like servers and can answer GNS requests. Just like everything else in IPX, you can filter the heck out of this with GNS filters.

That's my understanding. I'm sure someone will point out where I'm incorrect or misguided.

I didn't have a whole lot of IPX crap on my test. The stuff I had were more in refrence to how to set up IPX routing and where would you do it and how can you tell if it's running.......that kind of thing. Good luck

my buddy recently took the 607 and got hardly anything on ipx, so not to say don't study it but I wouldn't focus on it (i'm focusing more on ip than ipx for when I take the test)
