Neighbor Count is 4, Adjacent neighbor count is 2
4 neighbors − 2 adjacent = 2 neighbors not fully formed

A. The interface is part of the OSPF backbone area.The Evidence: Looking at the second line of the output, it explicitly states: Area 0.0.0.0.The Logic: In OSPF, Area 0 (or 0.0.0.0) is officially defined as the Backbone Area. All other areas must connect to this area to exchange routing information.B. There are a total of five OSPF routers attached to the Port4 network segment.The Evidence: Look at the line: Neighbor Count is 4.The Logic: The "Neighbor Count" represents the other OSPF routers that the local FortiGate sees on that specific segment. Since the local FortiGate itself is also an OSPF router on that segment, you add the local router (1) to the neighbors (4). 1 (Local FGT)} + 4 (Neighbors) = 5 Total Routers
