Question: What triggers an Home Subscriber Server (HSS) to include a Load Attribute-Value Pair (AVP) of type HOST in answer commands?
Option 1: Expiration of a predefined time interval
Option 2: Receipt of a specific query from the CSCF (Call/Session Control Function)
Option 3: Completion of a threshold number of concurrent sessions
Option 4: Implementation-specific determination based on internal resource usage and traffic
Explanation: An HSS's decision to send Load AVPs of type HOST relies on implementation-specific means, such as CPU usage, memory levels, traffic, and access to external resources, allowing for flexibility in managing load reporting based on the HSS's unique operational context.
