100-150 Question 99
Select 2A network technician is tasked with connecting several computers in a small office to a network switch. The switch supports both Fast Ethernet and Gigabit Ethernet connections. Which cables and connectors should the technician use to ensure compatibility and optimal performance?
- A
Cat5 cable with RJ45 connectors
- B
Cat5e cable with RJ45 connectors
- C
Cat6 cable with RJ45 connectors
- D
Fiber optic cable with SC connectors
- E
Coaxial cable with BNC connectors
Show answer and explanation
Correct answers: B, C
Explanation
For a small office LAN setup connecting to a switch that supports Fast Ethernet and Gigabit Ethernet, the most suitable cables are Cat5e and Cat6 with RJ45 connectors. These cables provide the necessary speed and reliability for both standards while being widely used in modern networks. Fiber optic and coaxial cables are not appropriate for this scenario due to their specialized use cases or outdated technology.
- A. Incorrect.
Cat5 cable with RJ45 connectors is outdated and may not reliably support Gigabit Ethernet, which limits compatibility and performance.
- B. Correct.
Cat5e cable with RJ45 connectors is a common standard for Fast Ethernet and Gigabit Ethernet, offering optimal compatibility and performance for this scenario.
- C. Correct.
Cat6 cable with RJ45 connectors supports both Fast Ethernet and Gigabit Ethernet and offers improved performance, especially for minimizing crosstalk.
- D. Incorrect.
Fiber optic cable with SC connectors is not typically used for local area networks in small office setups and requires specialized equipment, making it unsuitable for this task.
- E. Incorrect.
Coaxial cable with BNC connectors is outdated and not used in modern Ethernet-based LANs, making it incompatible with the network switch.
