Question: What does a Routing-Rule-Failure-Code AVP value of '3' indicate when sent by the Policy and Charging Rules Function (PCRF) to the Policy and Charging Enforcement Function (PCEF) in a telecom network?
Option 1: The NBIFOM routing rule installation failed due to operator policy restrictions.
Option 2: The NBIFOM routing rule modification was unsuccessful because of resource constraints on the network.
Option 3: There was an unspecified error preventing the installation or modification of the NBIFOM routing rule.
Option 4: The NBIFOM routing rule cannot be installed or modified as the routing access information is not allowed by the network.
Explanation: A Routing-Rule-Failure-Code AVP value of '3' indicates that the routing rule cannot be installed or modified because the network does not allow the required routing access information, highlighting policy enforcement and resource allocation decisions in telecom network management.
