The enterprise customer wants to stream one-way video from their head office to eight branch offices using multicast. Their current service provider provides a Layer3 VPN solution and manages the CE routers, but they do not currently support multicast. Which solution quickly allows this multicast traffic to go through while allowing for future scalability?
Enable a GRE tunnel between nodes CE1 and CE2
Enable a GRE tunnel between nodes C2 and C4
Enable a GRE tunnel between nodes C1 and C4
Implement hub and spoke MPLS VPN over DMVPN (also known as 2547o DMVPN) between CE1and CE2
The service provider must provide a Draft Rosen solution to enable a GRE tunnel between nodesPE1 and PE2
Correct answer: B
An enterprise network has two core routers that connect to 200 distribution routers and uses fullmesh IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process. Which design solution is the most cost effective?
Implement route reflectors on the two core routers
Increase the memory on the core routers
Implement e BGP between the core and distribution routers
Increase the memory on the distribution routers
Increase bandwidth between the core routers
Correct answer: A
You want to mitigate failures that are caused by STP loops that occur before UDLD detects the failure or that are caused by a device that is no longer sending BPDUs. Which mechanism do you use along with UDLD?
