Cisco CCNP Service Provider 300-510 Questions & Answers

• Question 201:

  An engineer is implementing LFA FRR on PE routers to allow unicast traffic to rapidly converge around link or node failures. The engineer configured IS-IS on the newly deployed routers in the data center in the same exchange as other routers. Which additional action must the engineer take before configuring LFA on the PE routers?

  A. Configure IP Cisco Express Forwarding on each router.

  B. Configure the isis network point-to-multipoint command on each router.

  C. Configure MPLS on each router.

  D. Configure the isis network point-to-point command on each router.

  Correct Answer: D

• Question 202:

  Refer to the exhibit.

  

  The UserA device fails to receive IPTV streaming traffic from the source. While debugging the issue, a network engineer finds that routers RB and RC receive the multicast traffic normally. RC receives subscription messages from UserA to join the IPTV stream. Which action must the engineer take on router RA to correct this problem?

  A. Change ip igmp version 2 to ip igmp version 3 on interface GigabitEthernet 1/0.

  B. Remove the ip pim ssm default configuration and replace it with ip pim rp-address 10.10.10.3.

  C. Configure ip pim bidir-enable in global mode and add ip pim rp-address 10.10.10.3.

  D. Configure ip pim ssm with ip igmp version 2 on interface GigabitEthernet 1/0.

  Correct Answer: A

• Question 203:

  Refer to the exhibit.

  

  Mid-sized company Z connected two branch offices via a multicast-enabled ISP using the BGP routing protocol. PIM was implemented to support multicast streaming between the branches via MSDP. Client A cannot connect to the multicast stream source of company Z. The network engineer ran a debug on the edge of the network as shown. Which action resolves the issue?

  A. Enable the BGP routing protocol and advertise the 10.10.10.0/24 subnet on R1.

  B. Deploy BSR on routers R1 and R2 and enable multicast on both LAN segments.

  C. Configure the PIM protocol on the Serial1/1 interface and enable Auto-RP.

  D. Implement MBGP and enable a multicast address family on R2.

  Correct Answer: D

• Question 204:

  Refer to the exhibit.

  

  R1 is sending data traffic to R6 using the same SRGB range as the other routers in the topology, but it is also using a non-default SRLB range. Which two configuration tasks must the engineer perform to enable normal SRGB and SRLB operations on this network? (Choose two.)

  A. Configure router R2 with adjacency SID 4002 to enable it to reach R4.

  B. Configure an adjacency SID from SRLB range 1002 to 6005.

  C. Set the SRGB range to 1002 to 6005.

  D. Configure router R1 with adjacency SID 1003 to enable it to reach R2.

  E. Set the default SRGB range to 16000 to 23999.

  Correct Answer: BE

• Question 205:

  Refer to the exhibit.

  

  Excessive routes are flooding from network 150.0.0.0 into AS100. Internet traffic between AS400 and AS300 is working normally. No route controlling mechanism is applied on incoming and outgoing traffic. Which configuration resolves the issue?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 206:

  Refer to the exhibit.

  1.

  The OSPF backbone area is configured to advertise loopback prefixes.

  2.

  The PE routers are running BGP-IPv4 address family in a BGP-free core topology.

  3.

  The DSL subscriber IP subnet 172.16.20.10/32 is redistributed in BGP on PE1. Which configuration on PE1 resolves the issue?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C
