A company wants to automatically retire hardware CIs that have been in an 'In Maintenance' state for more than 180 days without an active update. Which CMDB feature is designed to automate this lifecycle management workflow?
Medium2A technician wants to view the graphical relationship hierarchy of a Business Service and its underlying servers. Which feature should they open from a CI record?
Easy3An organization requires that network gear attributes can only be updated by the Network Discovery data source, while server attributes can be updated by both Discovery and a manual import set. Where must this restriction be configured?
Medium4An administrator needs to ensure that network gear discovered by Discovery is classified under a specific custom child table of cmdb_ci_netgear. Where should the administrator define the classification criteria to map network devices to this custom table?
Medium5Which THREE of the following actions can be performed using CMDB Data Manager? (Choose three.)
Hard6Which TWO factors should be considered when defining relationship rules between CI classes? (Choose two.)
Medium7While reviewing the CMDB Correctness score, an administrator notices a high count of orphan CIs. What is the definition of an orphan CI in the context of CMDB Health Correctness?
Hard8A custom integration script is inserting records directly into the cmdb_ci_server table without invoking the Identification and Reconciliation Engine (IRE). What is the primary risk of this approach?
Medium9A team wants to create a new relationship type to define a custom dependency between hardware and business applications. Which module should be used to define this new relationship type?
Easy10An auditor wants to verify the physical existence and accuracy of datacenter hardware CIs by having owners attest to their records. Which application provides this attestation capability?
Easy11Which THREE of the following metrics are tracked under the Correctness pillar of the CMDB Health Dashboard? (Choose three.)
Hard12An administrator needs to evaluate the overall health of the CMDB, specifically measuring the percentage of CIs that have not been updated or verified within the last 90 days. Which CMDB Health metric addresses this?
Hard13An engineer needs to add a custom attribute called 'Rack Number' to all Linux Server CIs. Where should this modification be performed to ensure it applies correctly to the table hierarchy?
Easy14An organization notices that manual updates made by technicians to the 'Assigned to' field on server CIs are frequently being overwritten by automated nightly imports. What is the best way to prevent this without disabling the import entirely?
Medium15Which TWO of the following are recommended best practices when configuring identification rules in the CMDB? (Choose two.)
Medium16An organization defines a multi-attribute identification rule for the Linux Server class using 'serial_number' and 'ip_address'. During a payload execution, the IRE finds an existing CI matching the serial number, but the IP address has changed. How does the IRE process this payload?
Hard17A team is importing asset and CI data from an external asset management tool. They want to ensure that when a CI is deleted in the external tool, it is also deleted in the ServiceNow CMDB. Which IRE payload setting accomplishes this?
Medium18Which THREE of the following are benefits of using CI Class Manager? (Choose three.)
Hard19During an import of server CIs, duplicate records are being created because different data sources send serial numbers in different cases (uppercase vs lowercase). Which configuration in Identification and Reconciliation Engine (IRE) will prevent this issue?
Hard20An administrator needs to review the overall CMDB health scores for Completeness, Correctness, and Compliance across all classes. Which application and module should they navigate to?
Easy21Which THREE of the following statements are true regarding Identification and Reconciliation Engine (IRE) processing? (Choose three.)
