- A
Twisted pair copper cable
- B
Fiber optic cable
- C
Coaxial cable
- D
RJ-11 cable
Show answer and explanation
Correct answer: A
Explanation
The correct answer is twisted pair copper cable because it is the standard cable type for Ethernet networks and is compatible with RJ-45 connectors. It is designed to reduce signal interference, making it suitable for connecting network devices over moderate distances.
- A. Correct.
Twisted pair copper cable, such as Cat5e or Cat6, is commonly used for Ethernet connections and connects to RJ-45 ports. It also minimizes signal interference due to its twisted pair design.
- B. Incorrect.
Fiber optic cable is used for high-speed and long-distance connections, but it does not connect to RJ-45 ports. It uses specialized fiber connectors like LC or SC.
- C. Incorrect.
Coaxial cable is primarily used for cable television or broadband internet connections and does not connect to RJ-45 ports.
- D. Incorrect.
RJ-11 cable is used for telephone connections and does not support Ethernet networking or RJ-45 ports.
