Question: What action should an NF take upon receiving a notification of user consent revocation for data processing subject to that consent?
Option 1: The NF can continue to process the data, but with limited access.
Option 2: The NF should ignore the notification and continue processing as usual.
Option 3: The NF shall no longer accept any service request for data processing subject to a revoked user consent and may notify other NFs to halt the processing of the data.
Option 4: The NF can choose to either delete or quarantine the data, but not temporarily retain it.
Explanation: Upon notification of user consent revocation, any NF that is deemed an enforcement point for user consent shall no longer accept any service request for data processing subject to a revoked user consent. This ensures that the NF respects the user's decision to revoke their consent and stops processing their data accordingly.
