A VoIP line will MOST likely have which of the following connectors?
The correct answer is D. RJ-45. VoIP phones connect to the network via Ethernet and therefore use RJ-45 connectors, as they rely on IP networks rather than traditional analog phone lines.

Why each option
VoIP phones connect to the network via Ethernet and therefore use RJ-45 connectors, as they rely on IP networks rather than traditional analog phone lines.
RJ-11 is the connector used for traditional analog PSTN telephone lines and is not used for IP-based VoIP Ethernet connections.
DB-25 is a serial or parallel port connector used for legacy peripheral devices and has no role in telephony or VoIP.
BNC connectors are used with coaxial cables in older 10Base-2 networks and video equipment, not in VoIP or Ethernet networking.
VoIP (Voice over IP) transmits voice as data packets over an IP network, which means VoIP phones and adapters connect to the network using standard Ethernet cabling terminated with RJ-45 connectors. This allows the devices to use standard network infrastructure including PoE switches that can power the phone over the same cable.
