PPP supports multipoint access networks with many stations. The all 1's acts as a broadcast. ✘ PPP supports multipoint access networks with many stations. The all 1's acts as a multicast. ✘ PPP supports point-to-point networks only. The address field is fixed. ✘ PPP supports point-to-point networks only. The address field can change dynamically since every station is assigned a PPP address. ✔

Ethernet 802.3 can only be used on point-to-point links, while Ethernet II can be used on broadcast networks. ✘ In Ethernet II the 2 bytes after the source MAC address is used as a type indicator. In Ethernet 802.3 these two bytes indicate the length of the frame. ✘ In Ethernet 802.3, the 2 bytes after the source MAC address is used as a type indicator. In Ethernet II these two bytes indicate the length of the frame. ✘ Ethernet II and Ethernet 802.3 are two different names for the same protocol ✔
