Adding Cisco Prime using discovery which protocol must be used when RTDM is processed?
A. OSPF
B. BGP
C. LLDP
D. ARP
Correct Answer: D
Explanation/Reference:
Explanation:
The ARP Discovery Module depends on the Routing Table Discovery Module (RTDM), and is executed only when RTDM is processed. This precondition is identified based on the flags processed by the ARP Discovery Module, which are part of the DeviceObject.
The entries coming out of the ARP Discovery Module do not need to pass through RTDM because (per the router Discovery algorithm) active routers are those that RTDM must process and identify.
When the ARP table is fetched and the entries are not already discovered by RTDM, these entries (though they may represent routers) are not active routers and need not be passed on to RTDM. This is ensured by setting the ARP Discovery Module flag to Processed and leaving the RTDM flag set to Unprocessed.
