Cisco CCNP Service Provider 300-510 Questions & Answers

• Question 41:

  Refer to the exhibit

  

  A network engineer installed a new router (router 3) at the regional hub running MPLS services for scalability Router 3 is connected to the 10.44 4.0/24. 10.44 5.0/24. 10 44.6.0/24. and 10 44.7.0/24 subnets

  The new router has been configured for OSPF area 2. and it is advertising the four connected networks.

  The engineer noticed that the same networks are listed as interarea summary routes, and they are being flooded into each area on the area borders

  Which action resolves the issue?

  A. On router 3, configure an access list to filter the networks.

  B. On router 2, configure a route map to filter the networks.

  C. Under the OSPF configuration on router 3. add area 2 range 10.44.4.0 255.255.252.0.

  D. Under the OSPF configuration on router 2, add area 2 range 10.44.4.0 255.255.252.0.

  Correct Answer: D

• Question 42:

  Refer to the exhibit.

  

  Multicast traffic destined from T1 and T2 routers to RP routers works well. A network engineer observes problems with multicast traffic flows between Site-A and Site-B. Site-A users fail to receive multicast stream on Site-B via RPTY site, while Site-B users fail to receive multicast stream on Site-Avia RPTZ site.

  Which action must be implemented to resolve the issues?

  A. Establish MDSP peering with interface IP subnet.

  B. Configure Site-A and Site-B in 10.80.14804

  C. Allow the OSPF and MSDP packets on the firewall.

  D. Configure direct OSPF peering between Site-A and Ste-B

  Correct Answer: C

• Question 43:

  How does SRv6 function on the control plane?

  A. It enables SRH-capable nodes to terminate IPv6 packets at the network egress to carry the SRv6 locator.

  B. The Ingress node of the SR domain adds a uSlD format IPv6 header to carry the SRv6 locator.

  C. The ingress node of the SR domain swaps the SRv6 header for the IPv6 header

  D. The egress node of SR domain imposes a new outer header

  Correct Answer: B

• Question 44:

  What is a requirement of PIM-SM?

  A. It requires Cisco Express Forwarding to be enabled.

  B. It must be enabled on loopback interfaces only

  C. It requires OSPF to be configured on the network.

  D. It must use an RP

  Correct Answer: D

• Question 45:

  Refer to the exhibit.

  

  A network engineer configured three new PE routers to expand the network.

  The new routers run in the IS-IS routing protocol and reside in the data center in the same exchange as the existing routers. However, the network is now experiencing suboptimal routing.

  The Layer 2 configuration and VLANs are configured correctly to provide segregation between networks, but the Level 1 routes are not being converted to Level 2 routes.

  Which action resolves the issue?

  A. On Router 1, redistribute the routes into IGP.

  B. On Router 1, summarize internal routes between areas.

  C. On Router 2, redistribute the routes into IGP.

  D. On Router 2. summarize internal routes between areas.

  Correct Answer: D

• Question 46:

  Refer to the exhibit.

  

  Customers A and C are experiencing packet drops when connecting to the application server While troubleshooting the problem the network engineer confirms that the IS-lS Level-1/2 adjacency is up between routers A B C. and D and both customers can communicate with the database server without packet loss Which action must the engineer take to resolve the issue?

  A. Advertise the application server subnet in the router D IS-IS database

  B. Advertise a static default route to the router B IS-IS database.

  C. Leak the 172, 17.10/24 route in the IS-IS databases on routers A and C.

  D. Leak the customer A and customer C subnets in the router A IS-IS database.

  Correct Answer: A

• Question 47:

  Refer to the exhibit

  

  After recent configuration changes to a customer's network, a network engineer notices that R2 cannot communicate with R3 Both FastEthemet interfaces on R2 and R3 are up and configured with the correct IP addresses MD5 password configured en R2 and R3 match with no issues.

  What is the minimum change the engineer must make to enable R2 and R3 to communicate and fix the problem?

  A. Configure a loopback interface on R2 and assign it to area 0.

  B. Define area 2 as a NSSA on R2 and R3

  C. Configure virtual links between RI and R3.

  D. Configure interface F0/0 on RI and R2 to be in area O.

  Correct Answer: A

• Question 48:

  Refer to the exhibit.

  

  A service provider has LDP and segment routing running in the network. Mobility traffic is carried through LDP and enterprise traffic is carried through segment routing. Which configuration must be implemented to connect the bank branch with the HUB site on routers?

  A. Configure segment-routing Sr-prefer prefix-list on AG1 and AG2 router for 10.10.10.10/24.

  B. Enable segment-routing Mpls Sr-prefer on CR1 and CR2 routers for 10.0.0.0/8.

  C. Enable segment-routing Mpls Sr-prefer on AG1 and AG2 routers for 10.0.0.0/8.

  D. Configure segment-routing sr-prefer prefix-list on CR1 and CR2 routers for 10.20.20.10/24.

  Correct Answer: D

• Question 49:

  Refer to the exhibit.

  

  After a recent network implementation project, customer A is performing stress testing to verify network redundancy at the branch office connected to R4.

  When the link from R2 is shut down as shown, the SLA tracking object fails and the cost of the link between R2 and R4 increases to 100. However, a traceroute operation from a PC in the Branch office shows that traffic to HQ is still routed via

  R2.

  Which solution corrects the problem and optimizes traffic flow via R3 without creating operational overhead?

  A. Configure two OSPF processes on R2 and R3 and redistribute traffic between them.

  B. Redistribute routes from BGP to OSPF as type El.

  C. Use multiarea adjacency to extend Area 10 to the link between R2 and R3.

  D. Create a virtual channel from R3 to R4.

  Correct Answer: B

• Question 50:

  What is the characteristic of enabling segment routing for IGPs?

  A. Segment routing must first be enabled under the routing process and then globally.

  B. Segment routing must first be enabled globally and then under the routing process.

  C. Segment routing must be enabled only globally.

  D. Segment routing must be enabled only under the routing process.

  Correct Answer: B
