A switch has learned the port associated with a frame's destination MAC address. What does it do with the frame?

  1. A

    It sends the frame to the router so the router can choose a port.

  2. B

    It forwards the frame toward the port associated with the destination MAC address.

  3. C

    It floods the frame to every port in every VLAN.

  4. D

    It replaces the destination MAC address with an IP address.

A host sends an IP packet to a destination on a different subnet. Which statement correctly describes the packet and the first Ethernet frame?

  1. A

    The host sends the frame directly to the remote host's MAC address.

  2. B

    The host changes the IP destination to the default gateway and sends the frame to the remote host's MAC address.

  3. C

    The host sends the frame to the default gateway's MAC address while the IP packet remains addressed to the remote host.

  4. D

    The host broadcasts the IP packet to all devices on its LAN.

Select all statements that correctly describe IPv6 address types.

  1. A

    Unique local addresses use the fc00::/7 range.

  2. B

    Link-local addresses use the fe80::/10 prefix and are not routed.

  3. C

    IPv6 uses broadcast addresses for group delivery instead of multicast.

  4. D

    An anycast address must be assigned to exactly one interface.

  5. E

    An anycast address can be assigned to multiple interfaces, with routing delivering traffic to one of them.

    A WAN, because it connects networks across larger distances

  3. C

    A VLAN, because it connects networks across cities

  4. D

    A link-local network, because it connects remote offices
