質問 8

Refer to the exhibit. A growing company with multiple internal networks asked the network- engineering team to improve communication between its internal networks, focusing on efficient data exchange. A network engineer is configuring IS-IS for route advertisement between routers R1 and R2, which are situated in different AS. The engineer configured R1 with IP address
192.168.1.1 and R2 with IP address 192.168.1.2 In accordance with RFC 1195 and IEEE 10589 standards. However, the routers failed to establish IS-IS adjacency via their GigabitEthernet0/0 interfaces. The engineer checked the cables and interfaces for any faults that might affect physical connectivity and verified the uniqueness of the routers' system ID. Which action must the engineer take to resolve the issue?

（A）Configure the same IS-IS level on both routers

（B）Change the IS-IS metric style to wide.

（C）Increase the IS-IS hello Interval.

（D）Change the IS-IS network type to point-to-point.

質問 9

Refer to the exhibit. All backbone interfaces on the network are in VRF_MPLS and ip rsvp signaling hello is preconfigured on all MPLS routers in the network. After router R2 was upgraded and its configuration restored from backup, LSP signaled via RSVP that the tunnel from R1 had been torn down.
The network engineer confirmed IP reachability within the backbone network. Which action must the engineer take to fix the issue?

（A）Configure ip rsvp udp neighbor 172.16.10.1 vrf VRF_MPLS under the global configuration on R2.

（B）Configure ip rsvp udp-multicasts 172.16.10.2 vrf VRF_MPLS under the interface Gi0/0 configuration on R1.
