Question: In an MCPTT (Mission Critical Push To Talk) system, when the IWF (InterWorking Function) floor control server is in the 'G: Floor Idle' state, which of the following timer(s) may be running concurrently?
Option 1: Only Timer T4 (Inactivity)
Option 2: Only Timer T7 (Floor Idle)
Option 3: Neither Timer T4 nor Timer T7
Option 4: Both Timer T4 (Inactivity) and Timer T7 (Floor Idle)
Explanation: In the 'G: Floor Idle' state of the IWF floor control server, no floor participant has permission to send media. This state allows for transitions based on inactivity (Timer T4) or the duration of the idle floor state (Timer T7). Thus, both timers can be running to manage the idle state effectively, monitoring both the lack of participant activity and the overall duration of the floor's idle status.
