Which should be used to explore the entire hierarchy and table definitions of the Configuration Management Database Classes?

The CI Class Manager is the centralized and dedicated tool within the ServiceNow platform designed for managing the Configuration Management Database (CMDB). It provides a user interface to explore the entire class hierarchy in a tree-like structure, view class definitions, manage attributes, define identification and reconciliation rules, and modify the CMDB data model. It is the primary tool for CMDB administrators to perform the tasks described in the question.

A. Application Menus are navigation elements used to access lists, forms, and modules, not to explore the hierarchical structure of database tables.
B. Reports are used to visualize and analyze data contained within tables, not to view or manage the underlying table definitions and class hierarchy.
D. Dependency View is a graphical tool that displays the relationships between specific configuration item (CI) records, not the class structure of the CMDB itself.
