Which type of network are distance-vector protocols best suited for?

A. Networks containing fewer than 255 routes
B. Networks containing fewer than 15 routers
C. Networks containing more than 15 routers
D. Networks containing more than 255 routers

B. RIP, which is a distance-vector protocol, is best suited for networks containing fewer than 15 routers. This is because RIP is limited to a 15 hop count. Any route that is more than 15 hops away is considered unreachable.
