100-150 Question 102
Single answerA network technician is tasked with connecting a desktop computer to a network switch located 15 meters away in an office environment. The connection must support Gigabit Ethernet speeds, and the cable should be cost-effective and easy to terminate on-site. Which cable and connector type should the technician use?
- A
Fiber optic cable with LC connectors
- B
Twisted pair copper cable with RJ-45 connectors
- C
Coaxial cable with BNC connectors
- D
Twisted pair copper cable with RJ-11 connectors
Show answer and explanation
Correct answer: B
Explanation
Twisted pair copper cables, such as Cat5e or Cat6, paired with RJ-45 connectors, are commonly used for Ethernet networking in office environments due to their cost-effectiveness, ease of installation, and ability to support Gigabit speeds over short to medium distances. This makes them the ideal choice for the given scenario.
- A. Incorrect.
Fiber optic cable with LC connectors is capable of supporting high data transfer speeds, but it is more expensive and typically used for longer distances or high-performance applications. It is not necessary for a 15-meter office connection.
- B. Correct.
Twisted pair copper cable with RJ-45 connectors is a cost-effective and commonly used solution for Gigabit Ethernet connections in office environments. It is suitable for the 15-meter distance and supports the required speed.
- C. Incorrect.
Coaxial cable with BNC connectors is not used for Ethernet networking in modern office environments. It is more common in legacy systems or specialized applications like CCTV.
- D. Incorrect.
Twisted pair copper cable with RJ-11 connectors is used for telephone lines and is not suitable for Ethernet networking or Gigabit speeds.
