What is the core CI table in ServiceNow?

1. cmdb_rel_ci

2. cmdb_ci

3. cmdb_ci_history

4. cmdb_rel_history

The correct answer is: cmdb_ci

The core CI table in ServiceNow is the cmdb_ci table. This table serves as the central repository for Configuration Items (CIs) within the Configuration Management Database (CMDB). Each record in this table represents a CI, which can be any component that needs to be managed in the IT environment, including hardware, software, documentation, and relationships between these components. The cmdb_ci table is fundamental because it not only stores primary CI information but also acts as the foundation for all other CI-related tables. When managing CIs in ServiceNow, administrators primarily interact with this table to accurately track and manage the lifecycle of each CI. This includes capturing attributes such as name, type, status, and various relationships to other CIs that are crucial for effective configuration management. Other tables mentioned, like cmdb_rel_ci and cmdb_ci_history, are related to specific functions within the CMDB ecosystem—such as tracking relationships between different CIs or maintaining historical changes of CIs—but they do not serve as the primary CI repository. Thus, they complement the cmdb_ci table rather than replace or compete with it for the role of core CI table.
