A.

Router R1 generates a type 4 LSA that is flooded to areas 0, 1, and 2.

B.

Router R3 generates a type 4 LSA that is flooded to areas 0, 1, and 2.

C.

Router R3 generates a type 4 LSA that is flooded to areas 0 and 2.

D.

Router R3 generates a type 4 LSA that is flooded to area 0, and router R6 generates a type 4 LSA that is flooded to area 2.

What happens by default on an Nokia 7750 SR when a VPLS accepts a tagged frame at the ingress SAP 1/1/1:100?

A.

The FCS is verified and kept in the customer frame. The VLAN tag is kept and transported over the network.

B.

The FCS is verified and kept in the customer frame. The VLAN tag is removed for transport over the network.

C.

The FCS is verified and removed from the frame. The VLAN tag is kept for transport over the network.

An LDP tunnel is established on router R1 towards router R6. The link between routers R2 and R4 goes down. What will happen to the MPLS data traffic to router R6 IMMEDIATELY after the link goes down?

A.

MPLS data traffic will be discarded until the IGP finds a new next-hop to router R3.

B.

MPLS data traffic will be discarded unless the LDP tunnel has a standby secondary path.

C.

MPLS data traffic will not be discarded because router R1 received labels from both next-hops, routers R2 and R3.

D.

MPLS data traffic will not be discarded because of fast reroute capability on router R2.
