Question: What is the purpose of the PCRF providing QoS parameters, including a reserved ARP value, when establishing a PDN connection towards the RLOS APN with a PDN GW?
Option 1: To prioritize regular PDN connections over RLOS connections in terms of admission control.
Option 2: To ensure that RLOS PDN connections are used only for Restricted Local Operator Services and have higher priority than regular PDN connections.
Option 3: To reject IMS sessions established via the RLOS PDN connection if the AF does not provide an RLOS indication to the PCRF.
Option 4: To guarantee QoS for voice services involved in Restricted Local Operator Services.
Explanation: The correct answer is Option 1 because, according to the text, the PCRF provides QoS parameters with a reserved ARP value that gives RLOS connections lower priority than regular PDN connections in terms of admission control. This ensures that regular PDN connections are prioritized over RLOS connections when network resources are limited.
