Question: In an MCPTT (Mission Critical Push To Talk) scenario, what triggers the Floor Control Server to set the state to 'U: not permitted but sends media' towards an MCPTT client?
Option 1: The MCPTT client requests floor control and is granted permission to send media.
Option 2: The MCPTT client stops sending RTP (Real-time Transport Protocol) media packets temporarily.
Option 3: Another MCPTT client is already in a permitted state to send media.
Option 4: The Floor Control Server receives RTP media packets from the MCPTT client despite the client not being permitted to send media.
Explanation: This question tests understanding of MCPTT floor control mechanisms. The correct answer highlights a key aspect of state 'U': the Floor Control Server enters this state when detecting an MCPTT client sending media (via RTP packets) without necessary permission, implying a misalignment between the client's actions and its assigned permissions.
