  Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window.

  All necessary preconfigurations have been applied.

  Do not change the enable password or hostname for any device.

  Save your configurations to NVRAM before moving to the next item.

  Click Next at the bottom of the screen to submit this lab and move to the next question.

  When Next is clicked, the lab doses and cannot be reopened.

  Topology

  

  Tasks

  Configure and verify an OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:

  1.

  R1 pings the Loopback0 interface of R2. Use interface-level configuration to complete this task.

  2.

  R2 pings the Loopback0 interface of R1. Use interface-level configuration to complete this task.

• Question 4:

  DRAG DROP

  Drag and drop the features from the left into the order of operations for SRv6 SRH field creation and forwarding on the right.

  Select and Place:

  

  Correct Answer:

  

  First - next header Second - routing type Third - segments left Fourth - last entry Fifth - segment list sixth - packet is forwarded

• Question 5:

  Refer to the exhibit.

  

  

  VPN users that are connected to PE routers are facing network issues. Traffic that originates from CE1 drops before reaching CE2. An engineer finds no outgoing traffic statistics on PE1 and PE2 routers toward CE devices and finds that the PE1 router is running the older software image. Which action must be implemented to resolve the issues?

  A. Enable LDP protocol on PE1 and PE2 routers.

  B. Advertise P1 router loopback on PE1 in OSPF.

  C. Enable CEF-based forwarding on PE1 router.

  D. Advertise PE2 router loopback on PE1 in OSPF.

  Correct Answer: C

• Question 6:

  Refer to the exhibit

  

  An engineer is configuring service traffic from router R1 to R6 as shown. Which additional configuration must the engineer implement so that the LDP and SR domains will participate and interwork with each other?

  A. Router2(config)# segment-routing Router2(config-sr)# ldp mapping-server Router2(config-sr-ms)# prefix-sid-map Router2(config-sr-ms-map)# Router2(config-sr-ms-map-af)# 2.2.2.2/32 500 range 4

  B. Router2(config)# segment-routing Router2(config-sr)# sr mapping-server Router2(config-sr-ms)# ldp-sid-map Router2(config-sr-ms-map)# address-family ipv4 Router2(config-sr-ms-map-af)# 10.1.1.1/32 500 range 50

  C. Router2(config)# segment-routing Router2(config-sr)# mapping-server Router2(config-sr-ms)# prefix-sid-map Router2(config-sr-ms-map)# address-family ipv4 Router2(config-sr-ms-map-af)# 10.1.1.1/32 500 range 50

  D. Router2(config)# segment-routing Router2(config-sr)# ldp mapping-server Router2(config-sr-ms)# prefix-sid-map Router2(config-sr-ms-map)# address-family ipv4 Router2(config-sr-ms-map-af)# 2.2.2.2/32 500 range 40

• Question 7:

  Refer to the exhibit.

  

  An engineer is troubleshooting connectivity issues on the MPLS core network. A customer connected through R4 cannot reach the OSPF domain on R5. While checking the routing table of R1, the engineer cannot see all the routes from R3 and R5. Which task must the engineer perform so that R4 is able to reach R5?

  A. Enable OSPF peering and configure route redistribution between routers R4 and R1.

  B. Enable route filtering between routers R1 and R3.

  C. Enable MP-BGP peering on routers R1, R3, R4, and R5.

  D. Enable OSPF on the Area-0 routers and configure MP-BGP between routers R1 and R3.

  Correct Answer: C
