Question

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?

Options

ACoaxial
BCAT3

Explanation

VoIP (Voice over Internet Protocol) transmits voice and fax data over an IP network rather than a traditional analog phone line. A fax card designed for VoIP connects to the local area network using a standard Ethernet cable. CAT6 is the modern Ethernet cable used for high-speed LAN connections and is the most likely cable type for such a setup. CAT3 is the old standard for analog PSTN telephone lines (RJ-11 jacks), which would not apply here because VoIP runs over an IP network, not the public switched telephone network. Coaxial and fiber cables are used in other contexts (cable internet, long-haul networking) and would not be used to connect an internal expansion card to a local network.
