To prevent Service Advertisements (SAPs) from flooding a network, Cisco routers do not forward them. How are services advertised to other networks?

A) Cisco routers filter out all SAPs

B) SAPs aren’t necessary with Cisco routers

C) Each router assigns a service number and broadcasts that

D) Each router builds its own SAP table and forwards that every 60 seconds

Correct Answer : Each router builds its own SAP table and forwards that every 60 seconds

Explanation : Cisco routers build SAP tables and forward the table every 60 seconds. All SAPs can’t befiltered even with 4.x since NDS and time synchronization uses SAPs.
