Question: In an IP Multimedia Subsystem (IMS) network, which of the following scenarios is NOT a primary application of load balancing for optimal resource utilization?
Option 1: Distributing incoming voice calls across multiple S-CSCFs (Serving-Call Session Control Functions)
Option 2: Balancing initial SIP requests for services across Transit Functions
Option 3: Managing congestion in User Equipment (UE) devices during peak usage hours
Option 4: Evenly distributing initial registration requests among multiple S-CSCFs
Explanation: Load balancing in the context of an IMS network focuses on distributing workload across network nodes to achieve optimal resource utilization. Managing congestion in User Equipment (UE) devices is more related to device or client-side management and not directly a function of load balancing across IMS serving network nodes.
