You Work as a Network Technician for the P4S Ltd

Multiple Choice

You work as a network technician for the P4S Ltd. Study the exhibit carefully, router P4S-RA is the hub router in a Frame Relay hub-and-spoke deployment. Configure router P4S-RA's serial interface as a point-to-multipoint interface, and it is servicing three spoke routers. The link between Router P4S-RC and the frame provider experiences a service disruption, which causes the interface on Router P4S-RC to go down. How does Router P4S-RA learn of this failure in the network and how does it react?

A) If OAM is configured between Router P4S-RA and Router P4S-RC, router P4S-RA will be notified of the failure after three missed OAM packets. After the third OAM packet is missed, the frame PVC becomes inactive, and this event terminates the routing process neighbor relationship established between Router P4S-RA and Router P4S-RC.
B) Router P4S-RA does not detect the failure in the network and its interface continues to remain in an operational state. If routing is configured over this link, Router P4S-RA must wait for the neighbor relationship to time-out before updating its routing table to account for the lost router and its networks.
C) Router P4S-RA must wait for a full LMI status update from the provider frame switch before it is notified about the PVC status. Once the full LMI status message is received, the routing process neighbor relationship between Router P4S-RA and Router P4S-RC is immediately terminated.
D) Router P4S-RA immediately detects the failure via LMI notification and its interface is placed in a non-operational state. If routing is configured over this link, the neighbor relationship is terminated and the routing table is updated. The change is then propagated as appropriate to the rest of the network.
