ServiceNow Certified System Administration 2025 – 400 Free Practice Questions to Pass the Exam

The correct choice highlights the key tables that form the foundation of Configuration Management Database (CMDB) functionalities within ServiceNow. The cmdb_ci table is essential as it stores configuration items (CIs), which are the fundamental entities managed in CMDB, such as servers, applications, and network devices. cmdb_rel_ci, on the other hand, captures the relationships between these CIs, detailing how they interact with one another. This relationship mapping is crucial for understanding the dependencies and impact of changes within IT environments.

In contrast, the other options, while they contain important tables, do not represent the primary base tables utilized specifically for CMDB purposes. For instance, the sys_user table is vital for user management, whereas the task and incident tables are part of the broader IT Service Management (ITSM) framework. However, they do not directly pertain to CMDB functionalities like the chosen answer. Therefore, focusing on cmdb_ci and cmdb_rel_ci underscores the essence of managing configuration items and their interrelations in ServiceNow.
