ServiceNow CIS-DF Exam Dumps

Comprehensive and Detailed Explanation (200--300 words):

In ServiceNow, the Compliance dimension of the CMDB Health Dashboard is driven by Data Certification. To surface meaningful compliance results---such as identifying servers that are not on the latest patch---the platform requires a combination of Certification Policies, Data Filters, and Scheduled Jobs.

Certification Policies define what data must be validated and which attributes are subject to compliance checks (for example, patch level, OS version, or last update date). Data Filters scope the population---such as server classes only---ensuring the compliance evaluation targets the correct CIs. Scheduled Jobs automate when certifications run, keeping compliance scores current and reflective of the latest state.

Options A and C are incorrect because audits and stale/orphan/duplicate checks relate to other health dimensions (correctness and completeness), not compliance. Option B focuses on service modeling and group alignment, which does not directly drive compliance scoring for patch currency.

Therefore, configuring Certification Policies, Data Filters, and Scheduled Jobs is required to accurately measure and display patch compliance on the CMDB Health Dashboard.

In ServiceNow, controlling source precedence when multiple authorized data sources update the same CI attributes is a core responsibility of Identification and Reconciliation Engine (IRE) governance.

The correct and supported method is to assign priority to each data source in reconciliation rules. Reconciliation rules determine which source wins when multiple sources attempt to update the same attribute on a CI. By defining source precedence, the Configuration Manager ensures that the most authoritative system of record (for example, Discovery over manual imports, or HR systems over spreadsheets) consistently controls specific attributes or classes.

Option B is incorrect because manually sequencing data source runs is unreliable, does not scale, and violates Data Foundations best practices. Option C only controls how often data is refreshed, not which source is authoritative. Option D is incorrect because identification rules are used to uniquely identify CIs---not to control attribute-level precedence.

Using reconciliation rules provides deterministic, auditable, and automated control, which is essential for maintaining CMDB trust and avoiding data conflicts.

Therefore, the correct answer is A -- Assign a priority to each data source in reconciliation rules.

When using Import Sets and Transform Maps to ingest data into the CMDB, it is critical that records are processed through the Identification and Reconciliation Engine (IRE) to prevent duplicates and enforce source precedence. In ServiceNow, this is achieved by invoking the IRE after the transform logic has completed.

The onAfter transform script is the correct place to call the IRE API. At this stage, the transformed data has already been mapped and prepared, allowing the IRE to correctly identify whether a CI already exists and reconcile updates according to defined rules.

The onBefore and onStart scripts execute too early---before data mapping is complete---making them unsuitable for IRE processing. The onComplete script runs after the entire import job finishes and is not intended for per-record CI identification and reconciliation.

Because Import Sets can bypass IRE if not configured correctly, using an onAfter script is a critical Data Foundations safeguard when this ingestion method is chosen.

Therefore, the correct answer is C -- onAfter.

The CMDB Data Foundations Dashboard is paired with Get Well Playbooks that guide administrators through structured remediation. The ''Services Have Owners Identified'' playbook focuses on closing ownership gaps for services, which is a governance and data correction activity.

Fix Data (Option A) is used to correct missing or incorrect values, such as populating owner fields, assigning responsible groups, or updating relationships. In this playbook, Fix Data actions are required to actually remediate the issue by assigning owners to services.

Govern Data (Option D) is also required because ownership is not a one-time correction---it must be enforced and sustained. Govern Data establishes policies, ownership accountability, and controls (such as certifications or attestations) to ensure services continue to have owners over time and do not regress.

Analyze Data (Option B) is used to understand patterns and root causes, but it does not remediate the issue. Report Data (Option C) provides visibility and communication, not corrective action.

Therefore, the remediation plays that apply to the Services Have Owners Identified playbook are Fix Data and Govern Data, making Options A and D correct.

In ServiceNow, validating whether Configuration Items (CIs) still exist is a core CMDB governance activity. Over time, environments change rapidly---servers are decommissioned, cloud resources are torn down, and applications are replaced. If existence validation is not enforced, the CMDB quickly fills with obsolete or ''ghost'' CIs.

Attestation policies are specifically designed to address this need. An attestation policy automatically generates and assigns tasks to responsible users or groups, asking them to confirm that a CI still exists and is still relevant. This process focuses on acknowledgment rather than deep data validation, making it lightweight and scalable across large CMDBs.

Certification policies (Option A) are used when specific attributes must be validated, such as lifecycle status, support group, or environment. While important for data correctness, certification is not intended solely to confirm CI existence. Delete (Option B) and Retire (Option C) policies are lifecycle actions that remove or transition records, but they do not validate existence before taking action.

Attestation integrates cleanly with CMDB Workspace, assigns tasks automatically, and supports auditability---ensuring accountability for CI ownership. This makes it the correct and Data Foundations--aligned policy type for validating CI existence.

Therefore, Option D -- Attestation is the correct answer.
