ServiceNow Certified System Administration Practice

The correct answer is a security rule defined and set at the row and column level. In ServiceNow, Access Controls are crucial for managing permissions related to tables and their records. They determine who can see and interact with specific data within those tables.

Access Controls can be configured to apply at different levels, such as table-level, row-level, and field-level (or column-level). By defining rules for each of these aspects, an administrator can effectively manage data visibility and modification rights based on user roles and conditions. This means that Access Controls can restrict access to certain records or specific fields within a record, ensuring that sensitive information is protected and only available to authorized users.

The other options do not accurately describe the function of Access Controls in ServiceNow. While the user permission scheme and table customizations are important aspects of ServiceNow's security and functionality, they do not encapsulate the role of Access Controls specifically. Additionally, data encryption protocols are related to data security but not to the management of access permissions at the row or column level.
