Q: 12
On an enterprise network, the directly connected interfaces of two OSPF routers are on different
network segments and have different masks. To establish an OSPF neighbor relationship between the
two interfaces, you can change their network types to which of the following?

Its A and C, since broadcast (D) and NBMA (B) still need matching masks which trips people up.
C or A both work, since P2P and P2MP types allow OSPF to form neighbors without matching subnet masks. I remember seeing a similar thing in official labs. Pretty sure that's the logic here.
A or C. Nice, clear question that checks real OSPF behavior on the mask rules.
