You are the lead IP network designer for a new service provider called XYZ, and you are working closely with the CTO to finalize design requirements. The CTO informs you that they want to transport IPv6 prefixes of customers through the XYZ network at this time; however, they need your advice on whether to deploy dual stack or MPLS 6PE/6VPE.
Which two options do you recommend? (Choose two.)

Refer to the exhibit. This DMVPN network is running OSPF in a single area. A network engineer notices that traffic destined to the data center from one of the spokes is using another spoke as the next hop. It is preferred that all traffic destined to the data center uses the least amount of hops.

Which solution resolves this issue with the minimum amount of changes on the network?

Voice traffic between two campus enterprise networks is growing. The network designers decide to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in order to provide more bandwidth and diversity. The QoS profile will be the same on the new 10-Mb service due to the voice stability on the first Metro Ethernet link. When the second link is added to the OSPF domain, which traffic design consideration would have the most impact on the voice traffic when both links are active?

Refer to the exhibit. A service provider using IS-IS has designed this network with all core links at the Layer 2 control plane. How will they adjust the design to reduce the flooding of update packets?

Which option describes a design benefit of Bridge Assurance?
