Which two multicast protocol statements are true? (Choose two.) A. Dense mode multicast requires explicit join messages from their members. B. Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the unwanted traffic. C. Sparse mode multicast uses a pull model to send multicast traffic to where it is requested. D. Sparse mode uses reverse path forwarding (RPF) to prune off redundant flows. E. The primary use of sparse mode multicast is for test labs and router performance testing.

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.

Which two statements are true about external BGP neighbor relationships? (Choose two.) A. Static routes or an interior gateway protocol is required between EBGP neighbors. B. EBGP neighbors must be in different autonomous systems. C. EBGP neighbors use TCP port 179 to exchange BGP routing tables. D. Loopback addresses should be used between EBGP neighbors. E. The BGP split-horizon rule specifies that routes learned via IBGP are never propagated to other EBGP peers. F. When an EBGP neighbor receives an update from another EBGP neighbor, it should not forward the update to other EBGP neighbors.
