Question: What is the primary purpose of the operator-controlled protection policy in the Security Edge Protection Proxy (SEPP)?
Option 1: To specify which types of data shall be decrypted.
Option 2: To define the roaming partners for the network.
Option 3: To determine which types of data shall be encrypted and to enforce a consistent ciphering of IEs on N32-f.
Option 4: To manage the release numbers of the policy.
Explanation: The operator-controlled protection policy in the SEPP is primarily used to specify which types of data shall be encrypted, such as SUPI, authentication vector, location data, cryptographic material, and authorization token. This policy ensures that the same data-types are encrypted consistently across different roaming partners, thereby enforcing a consistent ciphering of IEs on N32-f.
