A network technician has multimode fiber optic cable available in an existing IDF. Which of the following Ethernet standards should the technician use to connect the network switch to the existing fiber?

Answer options

• A. 10GBaseT
• B. 1000BaseT
• C. 1000BaseSX
• D. 1000BaseLX

Correct answer: C

Explanation

The correct answer is C, 1000BaseSX, as it is specifically designed for use with multimode fiber optic cables, allowing for transmission over short distances. Options A and B are intended for twisted pair copper cables, while D, 1000BaseLX, is meant for single-mode fiber and is not suitable for multimode applications.
