24. What will a Layer 2 switch do when the destination MAC address of a received frame is not in the MAC table?

It initiates an ARP request.

It forwards the frame out of all ports except for the port at which the frame was received.

It notifies the sending host that the frame cannot be delivered.

It broadcasts the frame out of all ports on the switch.

25. What are two features of ARP? (Choose two.)

When a host is encapsulating a packet into a frame, it refers to the MAC address table to determine the mapping of IP addresses to MAC addresses.

If a host is ready to send a packet to a local destination device and it has the IP address but not the MAC address of the destination, it generates an ARP broadcast.

If a device receiving an ARP request has the destination IPv4 address, it responds with an ARP reply.

An ARP request is sent to all devices on the Ethernet LAN and contains the IP address of the destination host and its multicast MAC address.

If no device responds to the ARP request, then the originating node will broadcast the data packet to all devices on the network segment.

26. What best describes the destination IPv4 address that is used by multicasting?

a single IP multicast address that is used by all destinations in a group

a group address that shares the last 23 bits with the source IPv4 address
