NEW QUESTION # 142
Refer to the exhibit.
An engineer working for a private telecommunication company with an employee id 3977 74 814 implemented the configuration on Router 1. what is the effect of it?
- A. Router 1 sends and receives multiple best paths from neighbor 192.168.1.1

- C. Router 1 sends only one best path to neighbor 192 168.1.1.

Answer: A
NEW QUESTION # 143
Refer to the exhibit.
A network operator is getting the route for 10.11.11 0/24 from two upstream providers on
#XR3. The network operator must configure #XR3 to force the 10.11.11.0/24 prefix to route via next hop of 10.0.0.9 as primary when available. Which of these can the operator use the routing policy language for, to enforce this traffic forwarding path?
- A. higher local preference on the prefix coming from 192.168.0.1
- B. lower local preference on the prefix coming from 192.168.0.2
- C. weight of 100 on the prefix coming from 192.168.0.1
- D. weight of 0 on the prefix coming from 192.168.0.2
Answer: D
Explanation:
Because Weight is the first attribute in path selection algorithm and is 0 for eBGP routes by default. If we set it to 0, router will continue from weight to the bottom, and when comparing neighbor router IDs it will find 192.168.0.1 less than 192.168.0.2 and st path will be selected as the best
NEW QUESTION # 144
Refer to the exhibit.
A network engineer has divided AS into confederations. Due to repeated ASN, when the 10.0 0.0/8 prefix from R1 arrives to R2, BGP automatically rejects it. What should the engineer do to fix the problem so that BGP allows that prefix on R2?
- A. Configure the command as-override on R2.
- B. Configure the command allowas-in on R2.
- C. Configure the command as-override on R1.
- D. Configure the command allowas-in on all the PE routers.

NEW QUESTION # 146
Refer to the exhibit. R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3.
Assume that there is no connectivity issue between R1, R2 and R1, R3.
Which result between BGP peers R1, R2 and R1, R3 is true?
- A. The BGP session does not come up between R1 and R2 and between R1 and R3.
- B. The BGP session comes up between R1 and R3, but not between R1 and R2.
- C. The BGP session comes up between R1 and R2, but not between R1 and R3.
- D. The BGP session comes up between R1 and R2 and between R1 and R3.
Answer: C
NEW QUESTION # 147
Refer to the exhibit. After you applied these configurations to routers R1 and R2, the two devices could not form a neighbor relationship.
Which reason for the problem is the most likely?
- A. The two routers have the same network ID.
- B. The two routers cannot authenticate with one another.
- C. The two routers have the same area ID.
- D. The two routers have different IS-types.
Answer: A
Explanation:
For those asking about the password, area authentication doesn't prevent neighboring to come up because it is carried only in LSP, CSNP and PSNP messages and not in IIH messages.

Answer: D
NEW QUESTION # 150
Which two statements about route reflectors are true? (Choose two.)
- A. If a route reflector receives a route with a cluster-list attribute containing a different cluster ID, the route is discarded.
- B. Routes received from nonclient peers are reflected to route reflector cluster as well as OSPF peers.
- C. Routes received from nonclient peers are reflected to route reflector clients as well as nonclient peers.
- D. If a router received an iBGP route with the originator-ID attribute set to its own router ID, the route is discarded.
- E. Routes received from a route reflector client is reflected to other clients and nonclient peers.
Answer: D,E

Which difference must an engineer consider when Implementing Inter-domain and Intra-domain multicast routing on the network?
- A. Intra-domain routing allows the service provider to control incoming and outgoing multicast data streams on its network, but inter-domain routing limits the service provider's control.
- B. Intra-domain routing uses the PIM and MBGP protocols for multicast routing, but inter-domain routing must use PIM.SSM or MSDP.
- C. Intra-domain routing is dependent on the RP router within the same SP network, but inter-domain routing reduces the dependency on the other SP network.
