A network administrator is troubleshooting a high utilization issue on the route processor of a router that was reported by NMS. The administrator logged into the router to check the control plane policing and observed that the BGP process is dropping a high number of routing packets and causing thousands of routes to recalculate frequently.

A network engineer is investigating a flapping (up/down) interface issue on a core switch that is synchronized to an NTP server. Log output currently does not show the time of the flap.
Which command allows the logging on the switch to show the time of the flap according to the clock on the device?

As the network administrator, you need to develop a verification plan for an OSPF network. The OSPF network has several area routers, area border routers (ABRs), and autonomous system boundary routers (ASBRs).
Which LSA types should you expect ABRs to generate while verifying the OSPF network? (Choose two.)

Automatic 6-to-4 tunnels exist between dual-stack routers (A, B, and C). One router has the IPv6 address, 2002:D030:6BC0:173C::26:37D0/48
Which of the following addresses is the IPv4 address of the router with the IPv6 address 2002:D030:6BC0:173C::26:37D0/48?

Company A recently acquired Company B and the network infrastructures are being merged. Both organizations used non-overlapping globally unique network addressing but different Interior Gateway Protocols (IGPs). Initially, multiple WAN links will connect the two organizations. Company A will maintain its core routing protocol, and Company B's routing protocol will be the edge routing protocol. Two-way redistribution will be used to ensure full network routing capability.
What additional routing configuration should be performed to prevent routing loops and suboptimal routing?
