Question: What is required for handling control plane data in cleartext within a gNB deployment?
Option 1: The entire gNB deployment must be placed in a physically secure location.
Option 2: Only the part of the gNB deployment that stores or processes control plane data in cleartext needs to be protected from physical attacks.
Option 3: Control plane data in cleartext can be stored and processed without any specific security measures.
Option 4: The gNB deployment must use encryption for all control plane data.
Explanation: According to the requirements, if a part of the gNB deployment stores or processes control plane data in cleartext, it shall be protected from physical attacks. If this is not feasible, then the whole entity should be placed in a physically secure location. This ensures that sensitive control plane data is handled securely within the gNB deployment.
