TestOut 3.2.4 Practice Questions and Answers Rated A+ Which of the following are advantages of using fiber optic cabling for a network? (Select two.) Greater cable distances without a repeater Immunity to electromagnetic interference Explanation Compared to other types of cabling, fiber optic cabling allows greater cable distances without a repeater and is immune to electromagnetic interference. However, it is more costly, difficult to work with, and specialized training and equipment is required for installation. Which of the following connectors are used with fiber optic cables and include both cables in a single connector? (Select two.) MTRJ LC Explanation LC and MTRJ connectors have both fiber optic cables in a single connector. ST and SC connectors hold a single strand of fiber optic cabling. A cable using either one has two connectors on each end. A BNC connector is used with coaxial cable. Which of the following cables offers the best protection against EMI? Single-mode Fiber Optic Explanation Fiber optic cables offer the best protection against electromagnetic interference (EMI). Which of the following are characteristics of an LC fiber optic connector? (Select two.) They use a housing and latch system similar to an RJ45 UTP connector. They are half the size of standard connectors. Explanation LC fiber optic connectors are small, at about half the size of other fiber optic connectors. Their appearance is similar to a typical RJ45 connector used with UTP wiring. Like an RJ45 connector, an LC fiber optic connector uses a small latch to lock the connector in a jack. ST uses a one-piece bayonet connecting system. Which of the following connectors is used with fiber optic cables and requires that you use a twisting motion to connect it? ST Explanation An ST connector is used with fiber optic cables and uses a twist-type connector. Use the mnemonic Set and Twist. An SC connector is used with fiber optic cables, but you plug it in instead of twist it in. F-type and BNC connectors employ a twist to connect, but they're used with coaxial cables. Which of the following are characteristics of an MTRJ fiber optic connector? (Select two.) They use metal guide pins to ensure accurate alignment. They can be used with multi-mode fiber optic cables.
