The router sends a copy of the LSP from its database to its neighbor ✘ The router updates its database with the LSP and floods a copy to its other neighbors. ✘ The router updates its database with the LSP, acknowledges the LSP with a PSNP and floods a copy to its other neighbors. ✘ The router updates its database with the LSP and acknowledges it with a PSNP. ✔

A packet with a destination anycast address is sent to all nodes on the local link. ✘ A packet with a destination anycast address is sent to all nodes on the local network. ✘ A packet with a destination anycast address is sent to all nodes that have joined the anycast group. ✘ A packet with a destination anycast address is sent to the nearest node that is assigned the anycast address ✔ A packet with a destination anycast address is sent to all nodes that are assigned the anycast address. ✔

L1 and L2 routers elect separate DIS's.

✘ DIS uses multicast address 0180x200:0015 to communicate with other routers on the broadcast network. ✘ If a new router starts up in a LAN and has a higher interface priority, the new router preempts the original DIS and becomes the DIS. ✘ In broadcast multi-access networks, such as Ethernet, a single router is elected as the DIS. There is no backup DIS ✔

IPv6 uses the Address Resolution Protocol to resolve the address to a MAC address. ✘ A Neighbor Discovery message is sent to the broadcast MAC address. The host with the IPv6 address responds with a Neighbor Advertisement message. ✘ A Neighbor Discovery message is sent to the solicited-node multicast address. The host with the IPv6 address responds with a Neighbor Advertisement message. ✘ A Neighbor Discovery message is sent to the anycast address for the LAN. The host with the IPv6 address responds with a Neighbor Advertisement message. ✔ IPv6 addresses do not need to be resolved to a MAC address. ✔

The router is an ABR. ✘ The router is an ASBR. ✘ The router is at the end of a virtual link. ✘ The router's interface is in a stub area. ✔
