Question 6

Which description of the RPF check in the multicast forwarding traffic is true?

Accepted Answer

Accepted Answer

A)  It is a best practice that the routers with the most powerful hardware should take the role of the DR and BDR. 
B)  If the IP OSPF priority is the same for all routers, the highest loopback IP address and router ID will decide which routers will take the DR and BDR role during the selection process. 
C)  To select the DR and BDR, the IP OSPF priority must be set to a higher value than the default value at the DR and BDR during the selection process. 
D)  To select the DR and BDR, the IP OSPF priority must be set to a lower value than the default value at the DR and BDR during the selection process. 
E)  The role for the DR and BDR will be selected when a new OSPF router comes up.
F) To force two routers to become a DR and a BDR, the IP OSPF priority can be set to zero at all other OSPF routers.
