CompTIA A+ (220-901) — Question 4

A technician is troubleshooting an expansion card in a computer that allows the computer to receive faxes over a VoIP line. The 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 CAT6, as it supports higher data rates and is suitable for VoIP applications. Coaxial and CAT3 are outdated for modern VoIP standards, while multi-mode and single-mode fiber are typically used for high-speed data transmission over longer distances rather than for fax over VoIP.
