An architect must design an IPv6 migration solution for an enterprise customer to support these requirements:
* Clients will transition to the new IPv6 network, which provides NAT64 and IPv6 DNS resolution services, using the same DNS name that points to the IPv4 address.
* The service provider will create a client-facing IPv6 interface with a new IPv6 virtual address that points to the same IPv4 DNS server.
* The service provider will support clients that use global IPv6 addresses and encapsulate IPv4 packets into IPv6 tunnels.
Which two migration solutions must the architect choose? (Choose two.)

An engineer is working for a large cable TV provider that requires multiple sources streaming video on different channels using multicast with no rendezvous point.
Which multicast protocol meets these requirements?

An engineer is designing an EIGRP network for a small branch site where there is only one Layer
3 router. The engineer wants the router to advertise the local LAN network to remote EIGRP neighbors without sending any unnecessary multicast messages on the local LAN.
Which action should the engineer take?

Refer to the exhibit. An architect must create a stable and scalable EIGRP solution for a customer. The design must:
* conserve bandwidth, memory, and CPU processing
* prevent suboptimal routing
* avoid any unnecessary queries
Which two solutions must the architect select? (Choose two.)

Which protocol is deployed through LAN automation to build node-to-node underlay adjacencies in SDA?
