Question: What is a key aspect of API provision for 5G LAN-VN (Local Area Network - Virtual Network) management by trusted third-parties, as per MNO (Mobile Network Operator) policy?
Option 1: Mandatory implementation across all 5G networks for any third-party.
Option 2: Exclusive use for public safety communications only.
Option 3: Limited to UE (User Equipment) authentication services solely.
Option 4: Conditional provision based on MNO policy, enabling control over creation, management, and UE authorization for specific 5G LAN-VNs.
Explanation: This option correctly reflects the nuanced understanding of 3GPP specifications regarding service exposure for 5G LAN-VN. The emphasis on "Conditional provision based on MNO policy" highlights the operator’s discretion in allowing trusted third-parties to manage aspects of the 5G LAN-VN, including its creation, ongoing management (e.g., address allocation), and authorization/deauthorization of UEs. This aligns with the practical application of telecom standards, where operator policies significantly influence network functionality and security.
