Which OSI layer provides services to the network layer directly? O IP Data Link Transport O O Physical Which layer is responsible for delivering data across a single hop (from one node to the next)? The network layer The physical layer The data link layer O The transport layer bytes The minimum frame length for Ethernet is O 64 54 1518 128 You just turned on a four port Ethernet switch (it hasn't learned any addresses yet), and connected a host to each port. No ARP is needed because the hosts have ARP cache. You send packet #1 from 00:11:22:33:44:55 to 66:77:88:99:00:11 which arrives at port 1 of your switch. Next, packet #2 is sent from 22:33:44:55:66 to 00:11:22:33:44:55 which arrives at port 3 of your switch. Which of the following are true? O After the second packet received, the switch associates 22:33:44:55:66 with port 1 O Packet #1 is sent out on ports 2,34 Packet #2 is sent out on ports 1, 2,4 O After the first packet is received, the switch associates 66:77:88:99:00:11 with port 1
