300-510 Question 53

Refer to the exhibit A network engineer installed a new router (router 3) at the regional hub running MPLS services for scalability Router 3 is connected to the 10.44 4.0,'24. 10.44 5.024. 10 44.6.0/24. and 10 44 7 0/24 subnets The new router has been configured for OSPF area 2. and it is advertising the four connected networks. The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders Which action resolves the issue?

Options:

A.

On router 3, configure an access list to filter the networks.

B.

On router 2, configure a route map to filter the networks.

C.

Under the OSPF configuration on router 3. add area 2 range 10.44.4.0 255.255.252.0.

D.

Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.

300-510 Question 55

What is the relationship between Router 1 and Router 2?

Options:

A.

Router 1 centrally learns the topology of the network to aid in SR-TE path selection, and Router 2 is a node that feeds Router 1 topology information.

B.

Router 1 and Router 2 are participating in SR-TE tunnels and are both head-end routers.

C.

Router 1 and Router 2 centrally learn the topology of the network to aid in SR-TE path selection for peers.

D.

Router 2 is the head-end router in an SR-TE tunnel, and it is learning topology of the network from the PCE enabled on Router 1.
