Which two statements are correct regarding the behavior shown in the exhibit? (Choose two.)
The router is an ABR (Area Border Router) because it has interfaces in different OSPF areas, specifically Area 0 and Area 100, indicating it connects these areas. The router is also not an ABR for the same reason.
B: ABR in areas 0 and 100 D: "Secondary interfaces are supported for LAN interfaces (the primary interface can be a LAN interface, but any secondary interfaces are treated as point-to-point unnumbered links over the LAN). In this scenario, you must ensure that there are only two routing devices on the LAN or that there are only two routing devices on the LAN that have secondary interfaces configured for a specific OSPF area."
