In ServiceNow, the "Allow access to this table via web services" option within the Application Access settings determines whether the table can be accessed through web service protocols, such as REST and SOAP. When this option is selected, it permits the table to be accessible via web services; however, it does not override existing permissions. The user or system making the web service request must still have the appropriate permissions (such as roles and access controls) to perform operations on the table's records.
Option A: Incorrect. If the "Allow access to this table via web services" option is not selected, the table is not accessible via web services, regardless of user permissions.
Option B: Correct. Enabling this option allows the table to be accessed via web services, but the user must have the correct permissions to access the table's records.
Option C: Incorrect. This option applies to all web service protocols, including both SOAP and REST.
Option D: Incorrect. This option controls overall web service access to the table; specific operations (create, read, update, delete) are governed by user permissions and access controls.
