Do they mean, "List four header fields that are used in data link frames?" or "List four possible values for the data-link header field 'type'? In the first case, any four frame header field should be okay. Google "Ethernet frame" or "ATM cell". In the second case, you might list the etherType values for IP, ICMP, ARP, and STP. Segments exist at the transport layer. I can't think of any interpretation where that's a good answer, since this question was asking about the data-link layer.
