A CMDB Administrator identifies duplicate CIs. One was created by a manual import, and the other was created by automated discovery. The discovered CI has the latest IP address, while the manually imported CI has an accurate relationship to a critical business application.

How does the Administrator use the Duplicate CI Remediator to resolve this issue?

  1. Merge the two CIs automatically, retaining all attributes from the discovered CI
  2. Retain the manually imported CI and delete the discovered CI
  3. Retain the discovered CI, but merge the relationship from the manually imported CI
  4. Retain the discovered CI and delete the manually imported CI

Answer(s): C

Explanation:

In ServiceNow, the Duplicate CI Remediator is designed to resolve duplicate records while preserving the most authoritative data from each source. Data Foundations guidance clearly states that automated discovery is the system of record for technical attributes, such as IP address, hostname, and operational status, while manually maintained records often contain valuable business context, such as relationships to business applications or services.

In this scenario, the discovered CI contains the most accurate and up-to-date technical data, making it the correct CI to retain as the primary record. However, the manually imported CI has a critical relationship to a business application, which is essential for impact analysis, incident prioritization, and CSDM alignment. Deleting this CI without preserving the relationship would result in loss of business context and reduced CMDB value.

The Duplicate CI Remediator supports selective merging, allowing administrators to retain one CI while merging specific attributes or relationships from the duplicate. Option C reflects this best practice by retaining the discovered CI and merging the relationship from the manually imported CI, ensuring both technical accuracy and business relevance are preserved.

Options A and D would result in the loss of important relationship data, while Option B would discard the discovered CI, violating the principle that discovery should be the authoritative source for technical attributes.

Therefore, Option C is the correct and Data Foundations­aligned answer.



What is the difference between Data Certification and Attestation policies when managing a CI?

  1. Attestation requires correcting specific attributes of a CI, while Data Certification tracks acknowledgement the CI still exists
  2. Attestation can be scheduled, while Data Certification cannot be scheduled
  3. Attestation can be assigned to a group or an individual, while Data Certification can only be assigned to an individual
  4. Attestation tracks acknowledgement the CI still exists, while Data Certification requires validating specific attributes of a CI

Answer(s): D

Explanation:

Within ServiceNow CMDB governance, Attestation and Data Certification serve distinct but complementary purposes. The key difference lies in what is being validated.

Attestation is focused on existence and ownership confirmation.
When a CI is attested, the assigned user or group is asked to confirm that the CI still exists, is still relevant, and is still owned or managed by the appropriate team. No detailed attribute-level validation is required. This lightweight process is commonly used to prevent "ghost CIs" from lingering in the CMDB.

Data Certification, on the other hand, is more rigorous. It requires the certifier to validate specific attributes of the CI, such as lifecycle status, support group, environment, or service relationships. Certification ensures data correctness and completeness, which directly impacts CMDB Health scores and downstream processes like Change and Incident Management.

Options A, B, and C incorrectly describe these mechanisms or their assignment and scheduling capabilities. Both attestation and certification can be scheduled and assigned flexibly, but their validation depth is what truly differentiates them.

Therefore, Option D correctly describes the distinction: attestation confirms existence, while data certification validates CI attributes.



CMDB class owners are receiving tasks under the "My Work" tab in the CMDB Workspace.

Which CMDB management tool is generating those tasks?

  1. De-duplication templates
  2. CMDB Data Manager
  3. CMDB Health Dashboard

Answer(s): B

Explanation:

The CMDB Data Manager is the ServiceNow capability responsible for generating actionable governance tasks and assigning them to CI class owners and data stewards. These tasks appear directly in the "My Work" tab within the CMDB Workspace, enabling proactive and role-based CMDB governance.

CMDB Data Manager focuses on data lifecycle management, including archival, retirement, and cleanup of CIs based on defined policies.
When lifecycle rules or retention thresholds are met--or when human validation is required--the Data Manager creates tasks to prompt responsible owners to take action. This ensures that CMDB data remains accurate, compliant, and lean over time.

The CMDB Health Dashboard (Option C) provides visibility into health metrics such as completeness, correctness, and compliance, but it does not generate tasks. Similarly, De-duplication templates (Option A) support duplicate identification and remediation workflows, but they do not create ongoing governance tasks in the CMDB Workspace.

By surfacing tasks in "My Work," CMDB Data Manager operationalizes governance and embeds accountability into daily workflows, which is a key principle of CMDB Data Foundations.

Therefore, the correct answer is Option B ­ CMDB Data Manager.



The CMDB Administrator group aims to display meaningful results on the CMDB Health Dashboard ­ Compliance Scorecard for server records that are not on the latest patch.

What must be configured to achieve this goal?

  1. Certification Filter, Certification Template, Audit
  2. Technical Service Offerings, Dynamic CI Groups, CMDB Groups
  3. Stale, Orphan, Duplicate
  4. Certification Policies, Data Filters, Scheduled Jobs

Answer(s): D

Explanation:

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.



A CMDB Administrator needs to identify which attributes have been created specifically for the Windows Server class.

Which tab in the Attributes section is used?

  1. Child
  2. Added
  3. All
  4. Derived

Answer(s): B

Explanation:

Within the CMDB class dictionary in ServiceNow, attributes can be inherited from parent classes or defined directly on a specific class. To identify attributes created specifically for the Windows Server class, administrators must use the Added tab.

The Added tab displays attributes that are unique to the selected class and not inherited from parent classes (such as Server or Computer). This is essential for understanding class-specific extensions-- like Windows-only configuration details--that were introduced to support platform requirements, discovery enhancements, or organizational needs.

The All tab shows every attribute available to the class, including inherited and added attributes, which makes it difficult to isolate class-specific additions. The Child tab focuses on attributes inherited by subclasses, not attributes introduced at the current class level. The Derived tab shows attributes calculated or derived from other data, not necessarily those created specifically for the class.

Using the Added tab supports best practices for configuration transparency, impact analysis during upgrades, and governance--especially important in Data Foundations to minimize unnecessary customization and maintain upgrade-safe designs.

Therefore, the correct answer is B ­ Added.
