Question: In a 5G Network Resource Model (NRM), when applying a Radio Resource Management Policy (RRMPolicy) to an `NRCellCU`, what determines the specific RRM resource(s) to which the policy is applied?
Option 1: The type of User Equipment (UE) connected to the NRCellCU
Option 2: The `resourceType` attribute defined for the `NRCellCU`
Option 3: The overall network congestion level at the time of policy application
Option 4: The specific slice of the 5G network the NRCellCU is serving
Explanation: According to the NRM specifications, when a RRMPolicy is applied to an `NRCellCU`, the `resourceType` attribute specifically defines which RRM resource(s) owned by the `NRCellCU` will be subject to the policy. This ensures targeted management of radio resources within the cell's central unit.
