In ServiceNow, the CMDB Health Dashboard does not calculate health scores in real time by default. Instead, health scores are generated and refreshed by scheduled calculation jobs that evaluate CI data against defined health rules across the dimensions of completeness, correctness, and compliance.
To generate and maintain CMDB health scores, the scheduled jobs for CMDB Health must be active. These jobs periodically scan the CMDB, apply health rules (for example, required attributes populated, lifecycle status compliance, certification results), and calculate scores that are displayed on the dashboard and scorecards. Without these scheduled jobs running, the dashboard cannot produce current or meaningful health metrics.
Option B is incorrect because CMDB health scoring is not automatic or real-time; it depends on scheduled processing. Option C is also incorrect because CMDB Health is part of the core CMDB/Data Foundations capability in ServiceNow and does not require a separate “CMDB health calculation” plugin to be installed in modern implementations.
Activating and maintaining these scheduled jobs ensures that health scores remain accurate, trendable over time, and useful for governance decisions. This is a foundational requirement for using the CMDB Health Dashboard as a data quality improvement tool.
Therefore, the correct answer is A – The scheduled jobs for the CMDB Health Dashboard must be activated.
