• Question 151:

  Which of the following describes the method used to resolve an IPv6 address to a MAC address?

  A. IPv6 uses the Address Resolution Protocol to resolve the address to a MAC address.
  B. A Neighbor Discovery message is sent to the broadcast MAC address. The host with the IPv6 address responds with a Neighbor Advertisement message.
  C. A Neighbor Discovery message is sent to the solicited-node multicast address. The host with the IPv6 address responds with a Neighbor Advertisement message.
  D. 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.
  E. IPv6 addresses do not need to be resolved to a MAC address.
  C. A Neighbor Discovery message is sent to the solicited-node multicast address. The host with the IPv6 address responds with a Neighbor Advertisement message.

• Question 154:

  Which of the following statements regarding OSPF routing updates on a multi-access network segment is true?

  A. In multi-access networks, a DR and BDR are elected only if there are more than two routers connected to the network segment.
  B. In multi-access networks, a DR and BDR are elected only if the subnet masks on the router interfaces are less than /30
  C. In multi-access networks, a DR and BDR are elected. To ensure resiliency, both the DR and BDR send link-state advertisements describing the network.
  D. In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.
  D. In multi-access networks, a DR and BDR are elected. The DR sends link-state advertisements describing the network.
