Which two factors influence the roaming decision of a wireless client? (Choose two.)

SNR is a useful RF quality metric but it is the client-side RSSI threshold and roaming algorithm that actually drive the roaming decision, not SNR directly.

The AP's channel number is a parameter the client learns after associating or scanning; it does not influence whether or when the client decides to roam.

RSSI is the primary RF metric clients monitor to detect a degrading connection; when RSSI falls below a threshold defined by the client driver, a roaming scan or handoff is triggered.

AP transmit power affects coverage cell size on the infrastructure side but is not a variable the client measures or evaluates when making a roaming decision.

Each client uses its own vendor-specific roaming algorithm that sets the thresholds, timing, and logic for when to roam, meaning two clients in identical RF conditions may roam at different times.
