Question: In the context of Quality of Experience (QoE) measurement collection Integration Reference Point (IRP), what encoding style is utilized in the WSDL file for Solution Set (SS) definitions?
Option 1: SOAP Encoding Style
Option 2: REST Encoding Style
Option 3: Literal Encoding Style
Option 4: RPC Encoding Style
Explanation: The correct answer is 'Literal Encoding Style' because it is explicitly used in the WSDL file, as per supported specifications for QoE measurement collection IRP. This choice significantly impacts telecom networks by affecting data type definition and serialization in web service interactions, influencing interoperability and interface definition simplicity. Literal encoding style typically offers more flexibility and clarity in defining message structures.
