Question: What triggers a Home Subscriber Server (HSS) to include a Load Attribute-Value Pair (AVP) of type HOST in answer commands, as per Diameter protocol?
Option 1: Expiration of a predetermined time interval
Option 2: Implementation-specific load calculation thresholds (e.g., CPU usage, traffic over S6a/d interfaces)
Option 3: Receipt of a specific command from the Mobility Management Entity (MME) or Serving GPRS Support Node (SGSN)
Option 4: Completion of a database synchronization with external resources
Explanation: The decision to send Load AVPs of type HOST is based on implementation-specific means, which can include reaching certain thresholds in load calculations (e.g., high CPU usage, significant traffic over S6a/d interfaces), determined through internal logic rather than external triggers or fixed intervals.
