An IPv6 overlay tunnel is required to communicate with isolated IPv6 networks across an IPv4 infrastructure. There are currently five IPv6 overlay tunnel types. Which three IPv6 overlay tunnel statements are true? (Choose three.) A. Overlay tunnels can only be configured between border routers capable of supporting IPv4 and IPv6. B. Overlay tunnels can be configured between border routers or between a border router and a host capable of supporting IPv4 and IPv6. C. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv6-compatible, 4to6, and Multiprotocol Label Switching (MPLS) overlay tunneling mechanisms. D. Cisco IOS supports manual, generic routing encapsulation (GRE), IPv4-compatible, 6to4, and Intra-Site Automatic Tunnel Addressing Protocol (ISATAP) overlay tunneling mechanisms. E. An manual overlay tunnel supports point-to-multipoint tunnels capable of carrying IPv6 and Connectionless Network Service (CLNS) packets. F. Overlay tunneling encapsulates IPv6 packets in IPv4 packets for delivery across an IPv4 infrastructure.

What is the purpose of the eigrp stub configuration command? A. to increase scalability by limiting the EIGRP query range B. to reduce the size of the routing table by blocking the D EX (External EIGRP) routes into the EIGRP stub router C. to reduce the convergence time by enabling the EIGRP stub router to propagate the EIGRP queries from the EIGRP hub router D. to reduce the convergence time by enabling the EIGRP stub router to also perform query requests to the EIGRP hub router

Which statement is true about Protocol Independent Multicast Dense Mode (PIM DM) multicast routing? A. PIM DM supports shared distribution trees. B. If a port is pruned, the administrator must re-enable the port to support multicast traffic. C. The (S,G) state exists in every router, regardless of the presence of an RPF interface. D. Flooding of traffic only occurs in the beginning stages of routing. Afterwards, all necessary ports are pruned and multicast traffic is not sent across those interfaces.
