質問 1

Refer to the exhibit. Company_A hosts multiple online VoD platforms. R3 is connected to MAN with a 100 Mbps link. R2 has only a 10 Mbps connection, but it has the lowest number of hops to R1. A network engineer must allow users in area 49.421 e.2331.5548.7624.00 to access online library resources, using the best possible route toward the online platforms to guarantee the highest connection quality. After the engineer implements the requirements, they notice an excessive number of routes in the R4 routing table and high memory consumption on the router.
Which two actions must the engineer take to resolve the issue? (Choose two.)

（A）Create a route map on R3 and redistribute all routes from L2 into L1.

（B）Configure summary-address level-2 64.45.52.0 0.0.3.255 on R2.

（C）Create an access list on R2 and redistribute all routes from L1 into L2.

（D）Configure summary-address 64.45.52.0 255.255.252.0 level-1 on R3.

（E）Configure summary-address area level-1-2 64.45.52.0 255.255.252.0 on R3.

（B）A warning message displays by default when 850 prefixes are received.

（C）The BGP peer tries to reestablish the session after one minute.

（D）A BGP peer ceases when it receives 1001 prefixes.

（E）A BGP peer resets when it receives 1001 prefixes.

（F）A warning message displays by default when 750 prefixes are received.

（G）A BGP peer ceases when it receives 1000 prefixes.

質問 7

Refer to the exhibit. An engineer has configured all routers in the environment to run IS-IS Level 1 and Level 2 routing. The engineer wants traffic from R1 to R5 to pass via R2. but IS-IS routing has calculated the best path via R4. Which action corrects the problem?

（A）Configure routers R1, R4, and R5 for Level 2 routing only.

（B）Set the link metric for the link from router R1 to router R4 to 30 or more.

（C）Configure routers R1, R2, and R5 for Level 1 routing only.

（D）Set the link metric on R2 for the links from router R2 to routers R3 and R4 to 30 or more.

質問 11

An engineer applied the summarization configuration on R1 for four networks (192.168.20.0/24 to
192.168.23.0/24) in area 1 and eight networks (192.168.32.0/24 to 192.168.39.0/24) in area 2 to stop the flooding of all the customer routes. While checking the routing table of R2, the engineer noticed that R1 is still sending only specific routes to R2.
Which configuration should the engineer apply on R1 to summarize routes?

（A）

（B）

（C）

（D）

質問 14

Refer to the exhibit. The Cisco router has a single uplink to the upstream network, which is critical to the business. The router is configured for traffic steering with the Autoroute mechanism configured to steer all OSPF and IS-IS prefixes over non-shortest paths and divert traffic for those prefixes to the SR-TE policy. However, the Autoroute Announce functionality for all prefixes is not working. Which additional command set must the engineer configure on the router to correct this issue?

（A）
