Refer to the exhibit. Users connected to an application on 1.1.1.1 via routers CE1 and CE2 are complaining of frequent disconnections. While troubleshooting the issue, a network engineer with an employee ID: 1234:56:789 determined that the application itself is working normally, but the link connected to the 1.1.1.1 application is flapping. The users on CE1 and CE2 are accessing applications on 2.2.2.2 without difficulty. Which action resolves the issue?

• A.Disable split horizon on router R2.
• B.Enable passive interface on the router R3 Loopback1 interface.
• C.Redistribute CE1 routes on router R2.
• D.Enable route dampening on routers R1 and R2.

Refer to the exhibit. The networking team configured segment routing in the network with a unique range of labels assigned to each router. However, the maintenance of the network is becoming more difficult as additional routers are added. Which action must the team take to simplify the implementation?

• A.Set the same SRGB size on each node.
• B.Specify a custom prefix SID to distinguish each device.
• C.Disable the default preservation.
• D.Set the same SRGB on all routers.

An SP core is running PIM on the network. Multicast groups in this networkare in the 232.0.0.0/8 range. Which commandenables multicast routing operations without using an RP?

• A.ip pim bidir-enable
• B.ip pim register-source
• C.ip pim ssm default
• D.ip pim autorp

Refer to the exhibit. An enterprise is running OSPF within its network. Cisco Express Forwarding is enabled on all connected links between routers. Users on the network report that they cannot reach application servers connected to R1. While troubleshooting the problem, a network engineer checked the MPLS forwarding table and noticed that labels are missing for the link between R1 and R4. Which action must the engineer take to resolve the issue?

• A.Enable LDP on the link between R1 and R4.
• B.Configure the OSPF router ID on R1 and R4 as a loopback interface with a /32 mask.
• C.Implement a virtual link from R1 to either R2 or R4 so that R1 can connect to area 0.
• D.Place the R1-R2 and R1-R4 links into area 0.

A network administrator is planning an upgrade for a PE router that has BGP peering sessions with several CE routers. The SLA has stringent uptime requirements, so the administrator wants to implement BGP NSR with SSO to provide fast convergence during the upgrade. Which action must the engineer take as part of the NSR implementation?

• A.Configure the clear ip bgp 65514 soft in command on the PE and CE routers.
• B.Configure MPLS on the link between the PE and CE routers.
• C.Configure a VRF on each CE router on the interface that connects to the PE router.
• D.Configure the bgp graceful-restart command on the PE router.
