Question

WANs that need to interconnect a very large number of sites.

(a) bus

(b) two-tiered

(c) three-tiered

(d) ring

This question was addressed to me by my school principal while I was bunking the class.

I need to ask this question from Internetworking topic in portion Data Communications and Computer Networks of Computer Fundamentals

Answer 1

Right choice is (c) three-tiered

For explanation: Wide Area Networks that need to interconnect a very large number of sites, or are built using smaller routers that can support only a few serial connections, may find the two-tiered architecture insufficiently scalable.
