Which feature allows multiple participants on the line at the same time?

• A. Ring
• B. Consult
• C. Blind Transfer
• D. Conference

Answer: (D)

The feature being tested is conference. It creates a conference bridge that merges two active calls into one shared conversation, allowing multiple participants to hear and speak with each other at the same time. Ringing a line simply alerts a device to an incoming call and doesn’t bring others into the line. Consult is a transfer method where you talk to one person before transferring the caller to someone else, usually resulting in a two-party call after the transfer. A blind transfer sends the call to another party without you staying on the line to confer, so it doesn’t form a multi-person bridge. Conference specifically enables multiple participants to be connected on the line simultaneously, making it the correct choice.
