100-150 Question 100
Single answerA network technician is tasked with connecting two switches in a local area network (LAN) using a physical cable. The technician needs a cable that supports high-speed data transfer and uses RJ45 connectors. Which cable type is the most appropriate for this connection?
- A
Fiber optic cable
- B
Coaxial cable
- C
Cat5e Ethernet cable
- D
Serial cable
Show answer and explanation
Correct answer: C
Explanation
The Cat5e Ethernet cable is the most appropriate choice for connecting two switches in a local area network because it supports high-speed data transfer up to 1 Gbps and uses RJ45 connectors, which are standard for Ethernet connections in a LAN. Other cable types, such as fiber optic, coaxial, or serial, are either not compatible with RJ45 connectors or not commonly used for this purpose.
- A. Incorrect.
Fiber optic cables are used for high-speed, long-distance data transmission. However, they do not use RJ45 connectors and are not typically used for directly connecting switches in a typical LAN setup.
- B. Incorrect.
Coaxial cables are mainly used for cable internet and television connections, not for Ethernet or switch connections in a modern LAN.
- C. Correct.
Cat5e Ethernet cables support high-speed data transfer up to 1 Gbps and use RJ45 connectors, making them suitable for connecting switches in a LAN.
- D. Incorrect.
Serial cables are used for point-to-point communication, often for connecting devices like routers or modems, but are not used for Ethernet or switch connections.
