Cisco CCNP Service Provider 300-510 Questions & Answers

• Question 101:

  Which expression, when used with the as-path-set command, matches the AS path attribute of the route?

  A. neighbor-is

  B. dfa-regtex

  C. ios-regex

  D. Length

  Correct Answer: C

• Question 102:

  What is the purpose of a BGP confederation?

  A. It limits the number of routes a device receives from its peers, which reduces CPU load.

  B. It improves service by increasing the number of simultaneous iBGP peering sessions.

  C. It redirects traffic away from route reflectors, which reduces their operating load.

  D. It reduces the number of iBGP peers and increases stability.

  Correct Answer: D

• Question 103:

  Refer to the exhibits.

  

  All links inside the network are configured at a default cost of one inside the fully converged OSPF domain. Given the configuration from XR1, which interface does traffic from XR1 that is destined to the loopback interface of XR6 select for the exiting interface?

  A. Interface GigabitElhemet 0/0. The tie breaker of the node index priority is lower and trumps the path cost.

  B. Interface GigabitEthernet 0/1. The tie breaker of the path cost being lower. The node index priority does not impact this selection process.

  C. Interface GigabitEthernet 0/1. The tie breaker of the node index priority is lower and trumps the path cost.

  D. Interface GigabitEthernet 0/0. The tier breaker of the path cost being lower. The node index priority does not impact this selection process.

  Correct Answer: A

• Question 104:

  After changing the IP address on an IOS XR router, an engineer cannot ping the new address Which step did the engineer forget to complete?

  A. commit the configuration

  B. roll back the configuration

  C. save the running configuration

  D. merge the configuration

  Correct Answer: A

• Question 105:

  Refer to the exhibit.

  

  The green policy is designed with low delay, and the pink policy is designed with low cost. What is the next hop for node A on its way to node D, with the objective of achieving a low delay?

  A. 192.168.3.2

  B. 192.168.1.6

  C. 192.168.3.6

  D. 192. 168.1.2

  Correct Answer: D

• Question 106:

  Refer to the exhibit.

  

  Routers within the cluster are not receiving the desired prefixes. What must be done to fix the issue?

  A. Clients in that cluster must have full mesh connectivity between eBGP peers.

  B. No client-to-client must be disabled.

  C. Clients in that cluster must have full mesh connectivity between iBGP peers.

  D. No client-to-client reflection must be enabled.

  Correct Answer: C

• Question 107:

  Refer to the exhibit.

  

  What is the relationship between Router 1 and Router 2?

  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.

  Correct Answer: D

• Question 108:

  Refer to the exhibit.

  

  Routers R1, R2. R3, and R4 have been configured to run OSPF. and router R5 is running EIGRP Traffic from R1 to R5 is expected to pass via R4. but OSPF routing has calculated the best path via R3. Which action corrects the problem?

  A. Configure R3 to use metric-type 1 with a higher metric than R4.

  B. Configure R1 with a static route to the R5 networks and set R5 as the next hop.

  C. Reconfigure R1 in Area 0.

  D. Change the metric-type value on R3 to 2.

  Correct Answer: D

• Question 109:

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

  D. Configure routers R1, R2, and R5 for Level 1 routing only.

  Correct Answer: B

• Question 110:

  After an engineer configures BGP in R1, it starts receiving this message Jun 29 13:30:50.122: %BGP-5-ADJCHANGE: neighbor 192.168.10.1 Down User reset Jun 29 13:30:52.341: %BGP-3-NOTIFICATION: sent to neighbor 192.168.10.1 2/6 (unacceptable hold time) 0 bytes Which action makes the peering come back up again?

  A. Make a soft reset to the peer.

  B. Set up a minimum hold-down timer higher.

  C. Set up a hello timer higher.

  D. Set up a hold-down timer higher.

  Correct Answer: B
