DATA FOUNDATION EXAM Latest Update| A Comprehensive Review of 350 Multichoice Practice Questions and Answers with Detailed Rationale| Guaranteed Pass| Brand New!! Question 1 CMDB Data Quality Management A CMDB Administrator is reviewing CMDB health and notices multiple duplicate CIs. What is the primary negative impact of duplicates in the CMDB? A. They increase storage costs significantly B. They reduce the accuracy of incident and change impact analysis C. They slow down the CMDB Health Dashboard calculations D. They prevent Service Mapping from discovering relationships Correct Answer: B. They reduce the accuracy of incident and change impact analysis Rationale: Duplicate CIs in the CMDB create confusion about which CI is the true representation of an infrastructure component. This directly impacts incident and change management processes because impact analysis becomes unreliable when multiple CIs represent the same physical asset. While duplicates do affect storage and performance, the primary business impact is on ITSM processes that rely on accurate CMDB data. ________________________________________ Question 2 CI Class Creation Best Practices A CMDB Administrator needs to create a new CI class for network switches. According to ServiceNow best practices, what is the recommended approach? A. Create the class directly under the root cmdb_ci table with all attributes defined B. Extend from an appropriate parent class like cmdb_ci_ip_switch C. Modify the existing cmdb_ci_network class to include switch-specific fields D. Create a custom table with the prefix u_network_switch Correct Answer: B. Extend from an appropriate parent class like cmdb_ci_ip_switch Rationale: ServiceNow best practices recommend extending from an appropriate existing parent class to inherit common attributes, identification rules, relationships, and CMDB behaviors. This approach ensures upgrade safety and proper integration with the CMDB hierarchy. Creating under root cmdb_ci would require defining all attributes manually, and modifying existing classes is discouraged as it can cause upgrade conflicts. ________________________________________ Question 3 CMDB Health Dashboard Staleness Metric The Correctness Scorecard on the CMDB Health Dashboard shows a high number of stale CIs. Which field does the system use to determine if a CI is considered stale? A. sys_created_on B. sys_updated_on C. last_discovered D. first_discovered Correct Answer: C. last_discovered Rationale: The CMDB Health Dashboard uses the last_discovered field to calculate staleness. This field tracks when a CI was last discovered or refreshed by Discovery. Using this field rather than sys_updated_on ensures that manual updates to CIs do not incorrectly mark them as current when they haven't been confirmed by discovery. The default stale threshold is 60 days. ________________________________________ Question 4 Technology Management Service Offerings A CMDB Administrator has configured a Technology Management Service Offering with a Dynamic CI Group. Which group values are automatically synchronized to the member CIs? (Choose two.) A. Change group B. Approval group C. Support group D. Managed by group Correct Answer: A. Change group and C. Support group Rationale: When using Technology Management Service Offerings with Dynamic CI Groups, the offering-level group values are synchronized down to the member CIs. The specific group fields that can be automatically populated and maintained include Change group and Support group. The Managed by group and Approval group are not part of this automatic synchronization behavior. ________________________________________ Question 5 Relationship Modeling Between Application and Server Which relationship pair correctly represents the relationship between an Application and a Server in the CMDB? A. Application Used by::Uses Server B. Application Depends on::Depends on Server C. Application Runs on::Runs Server D. Application Hosts::Hosted by Server Correct Answer: C. Application Runs on::Runs Server Rationale: In the CMDB relationship model, the Application runs on a Server, and the Server runs the Application. ServiceNow relationship pairs are written with the parent relationship first, followed by the child relationship. The correct relationship pair is "Runs on" from Application to Server and "Runs" from Server to Application. ________________________________________ Question 6 Principal Class Configuration To restrict the number of CI classes available in the Configuration Item reference field on an Incident form, what configuration must be performed? A. Check the Principal Class checkbox on the CI Class Manager's Basic Info tab B. Configure the CI reference field properties to limit classes C. Use the CMDB Workspace to define allowed classes D. Create a system property to control displayed classes Correct Answer: A. Check the Principal Class checkbox on the CI Class Manager's Basic Info tab Rationale: Principal Classes are designated in the CI Class Manager on the Basic Info tab. When a class is marked as a Principal Class, its CIs appear in task-related CI reference fields such as Incident, Problem, and Change forms. This helps ensure users only see relevant, managed CI classes when selecting Configuration Items. ________________________________________ Question 7 Asset-CI Field Synchronization User endpoint devices are imported into the CMDB and populate the 'Assigned to' field on the Computer CI. The Asset team requests that the 'Assigned to' field on the related Asset be automatically populated. What is the recommended approach? A. Use the Asset-CI Field Mapping module to create a new rule B. Configure a business rule on the Computer table C. Create a scheduled job to sync the values D. Hide the asset field and use a dot-walk reference Correct Answer: A. Use the Asset-CI Field Mapping module to create a new rule Rationale: ServiceNow provides the Asset-CI Field Mapping capability specifically to synchronize fields between Assets and CIs automatically. This is the recommended OOB solution for Asset/CI synchronization. Business rules could work technically but are not best practice, and dot-walking only displays values without populating them on the Asset record. ________________________________________ Question 8 CMDB 360 Multisource Configuration A CMDB Administrator wants to enable CMDB 360/Multisource CMDB functionality. Which system property must be enabled? A. ification_source_enabled B. ification_ C. ification_source_non_cmdb_ci_enabled D. ification_source_cmdb_ci_enabled Correct Answer: A. ification_source_enabled Rationale: To enable CMDB 360/Multisource CMDB functionality, the main system property that activates multisource support is ification_source_enabled. The other properties are supplemental or specialized settings that do not enable the feature itself. ________________________________________ Question 9 Dynamic Reconciliation Rules A Windows Server class uses a dynamic reconciliation rule of "most reported" for Disk Space. Data sources report values of 75, 75, 50, and 80 GB. Which value is added to the CMDB? A. 50 GB B. 75 GB C. 80 GB D. No value is added due to conflict Correct Answer: B. 75 GB Rationale: The "most reported" rule chooses the value that appears most frequently across data sources. In this case, 75 GB appears twice, while 50 GB and 80 GB each appear once. The most reported value is 75 GB. This dynamic reconciliation rule type is available only when CMDB 360/Multisource CMDB is enabled.
