Question: In a shared E-UTRAN/NG-RAN setup, what is the primary reason for the Hosting E-UTRAN/NG-RAN Operator to control information exchange related to OA&M operations involving Participating Operators?
Option 1: To ensure uniformity in network upgrade schedules among all operators.
Option 2: To prevent disclosure of sensitive business, operational, or technical information to other Participating Operators.
Option 3: To streamline the process of allocating shared RAN resources during peak hours.
Option 4: To facilitate joint marketing campaigns by Participating Operators.
Explanation: Controlling information exchange is crucial in a shared E-UTRAN/NG-RAN environment to maintain confidentiality and security. This is particularly important for sensitive data that could impact the competitive stance, operational efficiency, or technical strategies of individual Participating Operators. By limiting access, the Hosting Operator protects not just its own interests but also those of all Participating Operators, ensuring a secure collaborative environment.
