Which of the following statements about the ARP process are true? (Choose 3)

A router will reply to an ARP request with the MAC address of the remote host if the IP address in not on the local network. A router will forward an ARP request out all ports except the one it came in on. A switch will forward an ARP request out all ports except the one it came in on. It is used when a device knows the IP address of a destination, but not the MAC address. It is used when a device knows the MAC address of a destination, but not the IP address. A router will reply to an ARP request with the MAC address of its interface on which the request came in, if the IP address is not on the local network.

Which sublayer is responsible for communicating directly with the Physical Layer?

MAC

a three-byte code that is assigned by IEEE to identify the vendor of a NIC

Organizationally Unique Identifier

a feature that detects the type of cable, and configures the interfaces to allow the connection

auto- MDIX

a message that is sent from a single sender to all recipients

broadcast

a switching method that begins the forwarding process as soon as enough information has been received to make a forwarding decision

cut-through switching

a cut-through switching method that beings to forward data as soon as the destination address has been received.

fast-forward switching

a cut-through switching method that begins to forward data after receipt of the first 64 bytes of a frame

fragment-free switching

a layer 3 address that identifies both the network and the specific host on that network

logical address

a message that is sent from a single sender to a group of recipients - more than once, but not all

multicast

a Layer 2 address that allows NICs to communicate with each other

physical address
