Q
To prevent Service Advertisements (SAPs) from flooding a network, Cisco routers do not forward them. How are services advertised to other networks?
AA. Each router builds its own sap table and forwards that every 60 seconds
BB. Each router assigns a service number and broadcasts that
CC. Saps aren’t necessary with cisco routers
DD. Cisco routers filter out all saps
Correct Answer:
A. A. 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.
