Study Notes
Network Cabling - Practice Questions
-
Q1: For a home entertainment system connecting to a TV and cable modem, RG-6 coaxial cable is recommended for optimal performance, given electrical characteristics.
-
Q2: In office environments with high electromagnetic interference (EMI), Shielded Twisted Pair (STP) cabling is best for protection, as Unshielded Twisted Pair (UTP) is less effective. Plenum-rated cabling is not specifically for EMI protection, but instead for fire safety from toxic fumes.
-
Q3: To support 1 gigabit per second data transmission over 100 meters, minimizing cost, Category 5e twisted pair cabling is recommended for compatibility with the 1000BASE-T standard.
-
Q4: To connect two PCs directly for file transfer without a switch, use a crossover cable to allow effective communication.
-
Q5: For long-distance fiber optic networks minimizing data corruption from multimode delay distortion, Single Mode Fiber (SMF) is the preferable choice over Multimode Fiber (MMF).
-
Q6: In high-density fiber network panels, the MTRJ connector is best for maximizing port density, compared to ST, LC, and SC connectors.
-
Q7: For a campus fiber optic network, supporting 1 gigabit per second with distances not exceeding 220 meters, 1000BASE-SX with multimode fiber is financially and practically optimal
-
Q8: PoE (Power over Ethernet) is the ideal technology to power devices like IP cameras and wireless access points, reducing reliance on extra power outlets in a new office building.
-
Q9: A potential cause for high input/output errors on router interfaces is a duplex mismatch (one end of the connection is half-duplex, the other is full-duplex), which decreases performance and increases errors.
