However, a possible answer is 2 or more, that is the number of LAN interfaces that appears as outgoing interfaces/next-hops. The serial interface is a separate broadcast domain / IP subnet but it is point to point link. Nothing can be said about the remote IP subnets we can guess that IP subnet 192.168.90.0/24 belongs to a LAN interface of another router. This can be counted as the third broadcast domain.
For example, IP addresses of networks with subnet masks of at least 24 bits ending in .0 or .255 can never be assigned to hosts. Such last addresses of a subnet are considered broadcast addresses and all hosts on the corresponding subnet will respond to it.very IP address on my network except .0 or .255 could access every site, IP addresses ending in .0 and .255 could access 95% of sites, but there were two or three completely different sites that they couldn't access.
