Question: What is the primary purpose of the UE-Usage-Type Attribute Value Pair (AVP) in the context of Diameter protocol for Mobility Management Entity (MME) and Serving GPRS Support Node (SGSN) interfaces?
Option 1: To prioritize Diameter messages based on network congestion
Option 2: To select a specific Dedicated Core Network (DCN) based on UE's usage characteristics
Option 3: To set Quality of Service (QoS) parameters for User Equipment (UE)
Option 4: To authenticate User Equipment (UE) before granting network access
Explanation: The correct answer is Option 2 because the UE-Usage-Type AVP indicates the usage characteristics of the User Equipment (UE), enabling the selection of a specific Dedicated Core Network (DCN) for efficient network resource allocation and management, based on anticipated UE usage patterns.
