CompTIA A+ (220-901) — Question 40

A technician is troubleshooting an expansion card in a computer that allows the computer to receive faxes over a VoIP line. The telephone line connected to the expansion card is MOST likely which of the following cable types?

Answer options

• A. Coaxial
• B. CAT3
• C. CAT6
• D. Multi-mode fiber
• E. Single-mode fiber

Correct answer: C

Explanation

The correct answer is C, CAT6, as it is suitable for high-speed data transmission required for VoIP services. Coaxial (A) is not typically used for VoIP, while CAT3 (B) is an older standard that doesn't support the same bandwidth. Multi-mode fiber (D) and single-mode fiber (E) are used for different types of high-speed data transmission and are not applicable for the described scenario.
