Cisco CCNP Service Provider 350-501 Questions & Answers

• Question 151:

  After a series of unexpected device failures on the network, a Cisco engineer is deploying NSF on the network devices so that packets continue to be forwarded during switchovers. The network devices reside in the same building, but they are physically separated into two different data centers. Which task must the engineer perform as part of the deployment?

  A. Implement an L2VPN with the failover peer to share state information between the active and standby devices.

  B. Implement OSPF to maintain the link-state database during failover.

  C. Implement VRFs and specify the forwarding instances that must remain active during failover.

  D. Implement Cisco Express Forwarding to provide forwarding during failover.

  Correct Answer: C

• Question 152:

  The network team is planning to implement IPv6 on the company's existing IPv4 network infrastructure. The network currently uses IS-IS to share routes between peers. Which task must the team perform so that IS-IS will run in multitopology mode on the updated IPv6 network?

  A. Configure the links between the network routers as point-to-point.

  B. Configure the network routers to use metric-style wide.

  C. Configure the network routers as Level 2 routers.

  D. Configure the IS-IS IPv6 metric on the dual-stack links.

  Correct Answer: D

• Question 153:

  What must a network engineer consider when designing a Cisco MPLS TE solution with OSPF?

  A. The OSPF extensions and RSVP-TE must be enabled on all routers in the network.

  B. OSPF extensions for RSVP-TE are supported in Area 1.

  C. The OSPF extensions and RSVP-TE must be enabled on the egress routers.

  D. OSPF extensions for RSVP-TE are implemented in Type 6, 7, and 8 LSAs.

  Correct Answer: A

• Question 154:

  Refer to the exhibit.

  

  What is the purpose of this JSON script?

  A. It changes the existing password.

  B. It updates a user authentication record.

• Question 155:

  What is a characteristic of MVPN?

  A. It bypasses the use of MPLS in the service provider core and transmits packets using IP only.

  B. It uses pseudowires to route unicast and broadcast traffic over either a service provider MPLS or IP core.

  C. It allows VRF traffic to use the service provider MPLS VPN to route multicast traffic.

  D. It creates GRE tunnels to route multicast traffic over a service provider IP core.

  Correct Answer: C

• Question 156:

  Refer to the exhibit.

  

  Users in AS 65010 are connected with the application server in AS 65050 with these requirements:

  1.

  AS 65010 users are experiencing latency and congestion to connect with application server 172.16.50.10.

  2.

  AS 65030 must be restricted to become Transient Autonomous System for traffic flow.

  3.

  Links connected to AS 65020 and AS 65040 are underutilized and must be used efficiently for traffic. Which two configurations must be implemented to meet these requirements? (Choose two.)

  A. Apply the AS-Path route-map policy for traffic received from R3.

  B. Configure the route map to prepend the AS-Path attribute for R5-R3 BGP peering.

  C. Apply the MED route-map policy for traffic received from R4.

  D. Configure a higher Local preference for R5-R4 BGP peering.

  E. Configure the route map to set the MED 50 attribute for R5-R4 BGP peering.

  Correct Answer: BE
