An enterprise network has two core routers that connect to 200 distribution routers and uses full-mesh 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 effective?

• A.Implement eBGP between the core and distribution routers
• B.Increase the memory on the distribution routers
• C.Increase bandwidth between the core routers
• D.Increase the memory on the core routers
• E.Implement route reflectors on the two core routers

Which are two open-source SDN controllers? (Choose two)

• A.OpenDaylight
• B.Big Cloud Fabric
• C.Application Policy Infrastructure Controller
• D.OpenContrail
• E.Virtual Application Networks SDN controller

An ISP provides VoIP and internet services to its customers. For security reasons, these services must be transported in different MPLS Layer 3 VPNs over the ISP core network. The customer CEs do not have the ability to segment the services using different VLANs and have only one uplink interface that does not support VLAN tagging. How should you design the network to ensure that VoIP traffic that is received from the CE goes in the VoIP VPN, and that Internet traffic goes into the Internet VPN on the ISP PE devices?

• A.Use policy-based routing to direct traffic into the correct VRF
• B.Enable NBAR on the PE to direct the traffic into the correct VRF
• C.Extend the Layer 3 VPN toward the CE
• D.Use a secondary interface IP address to differentiate between VoIP and Internet traffic
• E.Use a subinterface on the PE for each service, VoIP and Internet, with different subnets

What is design considerations of policy-based routing?

• A.It routes traffic destined to a set of users through different exit points
• B.It decreases failure detection time
• C.It can create microloops during network reconvergence
• D.It uses RSVP to differentiate traffic flows, so queuing mechanisms can prioritize them
