Which port is used to perform leader elections between ensemble members?

• A. Leader port
• B. Election port
• C. Client port
• D. Data port

Answer: (B)

Leader elections among ensemble members rely on a dedicated inter-node channel. This election port is specifically used for the peers to exchange votes and coordinate which member should become the leader, independent of any client traffic or data transfer. The client port is reserved for clients connecting to the ensemble to issue requests, not for inter-member consensus. The other option names don’t reflect a standard inter-peer election channel in typical distributed ensembles. Therefore, the election port is the appropriate one for performing leader elections between ensemble members.
