QUESTION 264

which of the following descriptions about urpf loose mode is correct?

 

A.  It is typically used on point-to-point interfaces where the same interface isused for both directiongs of packet flows; if the source address has a return route in the FIB table,it is then checked against the adjacency table to ensure the same interface receiving the packet is the same interface used for the return path

B.  If a packet fails the uRPF loose mode check, the packet is then transmitted and creates a log message

C.  It is typically used on multipoint interfaces or on routers where asymmetrical routing is used(packets are received on one interface but the return path is not on the same interface);loose mode verifies a source address by looking in forwarding information base(FIB). Created by routing protocols, to verify there is a return route to the source and to venrify that the path uses a valid interface

D.  None of above

E.  If a packet fails the uRPF loose mode check ,the packet is then dropped

 

Answer: CE
