NEW QUESTION # 126
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 64.45.52.0 255.255.252.0 level-1 on R3.
- C. Create an access list on R2 and redistribute all routes from L1 into L2.
- D. Configure summary-address level-2 64.45.52.0 0.0.3.255 on R2.
- E. Configure summary-address area level-1-2 64.45.52.0 255.255.252.0 on R3.
Answer: B,D
Explanation:
Configure summary-address level-2 64.45.52.0 0.0.3.255 on R2:
This command summarizes the routes at Level-2 on R2. It helps to reduce the number of specific routes advertised toward Level-2 routers, which in turn optimizes R4's routing table and memory consumption.
Configure summary-address 64.45.52.0 255.255.252.0 level-1 on R3:
This creates a summary route for Level-1, consolidating routes that are more granular into a single prefix.
This reduces route advertisements in the Level-1 domain and minimizes routing table size.
The excessive routes and memory consumption issue is addressed through route summarization.
Summarizing routes:
- Reduces the number of routes that need to be stored.
- Optimizes router performance and memory usage.
- Ensures only essential routes are advertised into the routing domains (Level-1 and Level-2).
NEW QUESTION # 127
Refer to the exhibit.

- A. Enable route filtering between routers R1 and R3.
- B. Enable MP-BGP peering on routers R1. R3, R4, and R5.
- C. Enable OSPF peering and configure route redistribution between routers R4 and R1.
- D. Enable OSPF on the Area-0 routers and configure MP-BGP between routers R1 and R3.
Answer: C
NEW QUESTION # 128 
Refer to the exhibit. Why is neighbor 10.1.5.5 stuck in "2WAY" state?
- A. OSPF authentication has failed between R2 and 10.1.5.5
- B. Router ID 10.1.5.5 is not reachable from R2
- C. It is an expected behavior when OSPF network type is broadcast
- D. OSPF parameters (Area ID or hello interval) are mismatched between R2 and 10.1.5.5

NEW QUESTION # 140
Refer to the exhibit. A network engineer configured routers R1 and R5 to run in IS-IS Level 1 mode and router R6 to run in IS-IS Level 2 mode. All other routers are running as Level 1 / Level
2 routers. An engineer expects traffic from R1 to R6 to pass via R2, but IS-IS routing has calculated the best path via R4. Which action corrects the problem?
- A. Change the link metric for the link from router R1 to router R2 to 1.
- B. Configure all routers as Level 1 / Level 2 routers.
- C. Remove the link metric for the link from router R1 to router R2.
- D. Configure all routers as Level 1 routers.
Answer: A
Explanation:
The default link metric for IS-IS is 10, so changing the link from R1 to R2 to 1 will change the overall metric to R6 to 9 (8+1).
NEW QUESTION # 141
Refer to the exhibit.

The four routers in this network have formed adjacencies. Router R2 is an IS-IS level 1-2 router that connects to other areas, and the attach bit is set in the R2 level 1 LSP advertisements to R1. According to the network design, R2 should push level 2 routes from its routing table to the R1 routing table. However, R1 installed a default route in its routing table. Which action resolves this problem?

- B. Set the attach bit on R1and use a prefix list to filter prefixes from R2.
- C. Use the is-type level-1-2 backdoor command to unset the attach bit on R2 and configure a distribute-list to redistribute prefixes to R1
