Question: What is a key benefit of supporting APN-level load control in a network where a single PGW handles multiple APNs with different resource allocations?
Option 1: Improved mobility management
Option 2: Enhanced security features
Option 3: Simplified network configuration
Option 4: More effective load balancing and overload control
Explanation: Supporting APN-level load control allows for more effective load balancing and overload control, as it takes into account the different resource allocations for each APN. This is particularly important in scenarios where one PGW handles multiple APNs with varying loads, as it helps prevent overloading of specific PGWs and ensures a more evenly distributed network load.
