Two buildings on the London campus of a the TestKing Corporation must be connected to use Ethernet with a bandwidth of at least 100 Mbps. TestKing is concerned about possible problems from voltage potential differences between the two buildings. Which media type should be used for the connection?

A.    Coaxial cable

B.    Fiber optic cable

C.    UTP cable

D.    STP cable

E.    Nonę of the above

Answer: B Explanation:

Current Ethernet technololgy typically comes via either copper UTP or fiber ccables. In this scenario the distance between the buildings is only 55 meters so either copper or fiber could be used, as the distance limitation for 100M UTP Ethernet is 100 meters. However, fiber would be a better fit as it is not prone to errors that could occur due to the voltage potential differences. Because fiber is a dielectric materiał, it's not susceptible to electrical interference. FO-product vendors also claim that fiber systems make secure Communications easier. Interference immunity and lack of emissions are givens in FO systems and in the fiber medium itself.
