Remote Procedure Call impact on wan link

[TechBoyJK]

I came up to a question on an exam i took recently, and it stated that I need to reduce traffic across a wan link. It said I could either block netbios traffic or remote procedure call traffic, or something like that. I was just curious what the effect of remote procedure calls on a network were. im googling now, but I like the anandtech explanations i get...

no effect really. nebios is normally blocked because it uses broadcasts. Don't want broadcasts on a WAN link as all it does is eat up bandwidth.

-edit- for a more andvanced answer (and not what the question wanted) is RPC is frequently blocked for security reasons - spread of worms, limiting RPC to specific networks/hosts, etc.
