A host needs to communicate with neighbors on its link and also reach globally addressed destinations. Which statement about its IPv6 interface is correct?

  1. A

    An interface can have only one IPv6 address, so it must choose between link-local and global addressing.

  2. B

    An interface can have a link-local address and one or more global or unique local addresses at the same time.

  3. C

    A link-local address can be assigned only to routers, not to hosts.

  4. D

    A global address replaces the need for any link-local address.

A service assigns the same IPv6 address to interfaces at several sites so routing can direct each packet to one suitable site, typically the nearest. Which address type is being used?

  1. A

    It identifies a group, and packets are delivered to every interface in that group.

  2. B

    It is assigned to multiple interfaces, and a packet is delivered to one of them, typically the nearest according to routing.

  3. C

    It identifies exactly one interface, and packets are delivered to that interface.

  4. D

    It identifies an address that cannot be assigned to more than one interface.
