Question: What happens when a user requests Password Registration for a single or group of Barring Services other than "all Barring Services"?
Option 1: The network will process the request and assign a unique password to the specified service(s).
Option 2: The request will be denied, as only one common password for all Barring Services per subscriber is allowed.
Option 3: The network will prompt the user to confirm if they want to override the existing common password.
Option 4: The request will be put on hold until the user contacts customer support for further assistance.
Explanation: According to the telecom principles for managing Supplementary Services, a subscriber is only allowed to have one common password for all Barring Services. Therefore, requesting a password registration for anything less than "all Barring Services" would violate this rule, leading to the denial of the request. This ensures uniform security management across all Barring Services for each subscriber.
