How does a router decide where the contents of a received frame should be forwarded?
by matching destination IP addresses with networks in the routing table
by matching the destination IP address with IP addresses listed in the ARP table
by matching the destination MAC address with MAC addresses listed in the CAM table
by forwarding the frame to all interfaces except the interface on which the frame was received
2
Why is IP considered a best-effort protocol?
IP detects lost packets.
IP validates the content of the packets.
IP does not provide acknowledgment of the data delivery.
IP reorders the packet as they arrive at the destination host.
