Which feature allows you to manage custom fields in ServiceNow?

The Dictionary is the correct choice for managing custom fields in ServiceNow because it serves as a central repository for all table definitions and their respective fields in the platform. Within the Dictionary, developers can create, modify, and configure fields for any table, including specifying attributes such as field types, default values, visibility, and more.

The Dictionary functionality ensures that you can control and manage the definitions of both standard and custom fields, making it applicable for comprehensive data management.

The other options represent different functionalities within ServiceNow that do not specifically focus on the management of custom fields. For example, Table Designer is more focused on visualizing and managing tables at a high level rather than providing in-depth control over specific field attributes. Field Engineer is not a recognized feature relevant to field management, and Data Modeler, while it deals with data structures, lacks the targeted functionality of the Dictionary for handling field configurations specifically.
