Question: What is the primary concern regarding key management inside RNCs in exposed locations?
Option 1: Protecting subscriber specific session keys and long term keys used for authentication and security association setup.
Option 2: Ensuring that all keys are stored in a centralized location within the RNC.
Option 3: Allowing keys to be transmitted over the backhaul link without encryption.
Option 4: Using only short-term keys for authentication and security association setup.
Explanation: Protecting subscriber specific session keys and long term keys used for authentication and security association setup is crucial, as these keys are essential for securing communication between the RNC and the UE. If these keys are compromised, it could lead to unauthorized access and eavesdropping on sensitive information.
