Question: What is the primary purpose of assigning a content version to a QoS rule by the PCRF when the RuleVersioning feature is supported?
Option 1: To uniquely identify the QoS rule for its lifetime and ensure proper installation regardless of previous bearer procedure outcomes.
Option 2: To simplify QoS rule modifications by only updating the changed parameters.
Option 3: To enable the BBERF to report on QoS rule provisioning failures without content version information.
Option 4: To inform the AF about all QoS rules provisioned, regardless of their status.
Explanation: Assigning a content version ensures that each modification of a QoS rule includes all related content, guaranteeing the rule is installed correctly, even if previous bearer procedures' outcomes are unknown or not yet reported.
