100-150 Question 103
Single answerA network technician is tasked with connecting a new desktop computer to the office network. The computer will be placed 10 meters away from the nearest network switch. The technician needs to use a cable and connector type suitable for this distance and the RJ-45 port available on both the desktop and the switch. Which combination of cable and connector should the technician use?
- A
Twisted pair cable with RJ-45 connectors
- B
Fiber optic cable with SC connectors
- C
Coaxial cable with RJ-11 connectors
- D
Twisted pair cable with RJ-11 connectors
Show answer and explanation
Correct answer: A
Explanation
For a short distance of 10 meters, twisted pair cables (such as Cat5e or Cat6) with RJ-45 connectors are the most appropriate choice for connecting a computer to a switch. They are cost-effective, widely available, and support Ethernet standards commonly used in office networks. Other cable and connector combinations, such as fiber optic or coaxial with RJ-11, are either unnecessary or incompatible for this scenario.
- A. Correct.
Twisted pair cables with RJ-45 connectors are commonly used for Ethernet connections in networks within short to medium distances, such as 10 meters, and they are compatible with RJ-45 ports.
- B. Incorrect.
Fiber optic cables with SC connectors are used for high-speed data transmission over longer distances, typically beyond 100 meters, making them unnecessary for this scenario.
- C. Incorrect.
Coaxial cables are used in specific applications like cable internet and do not use RJ-11 connectors. RJ-11 connectors are typically used for telephone lines, not Ethernet connections.
- D. Incorrect.
RJ-11 connectors are designed for telephone networks and are incompatible with RJ-45 ports on network devices. Twisted pair cables with RJ-11 connectors would not work for Ethernet connections.
