1On the CMDB Health Dashboard, which three top-level KPIs aggregate to measure overall CMDB data quality?
A.Accuracy, Currency, and Coverage
B.Validity, Integrity, and Freshness
C.Discovery, Reconciliation, and Normalization
D.Completeness, Compliance, and Correctness
Explanation: The CMDB Health Dashboard scores data quality across three KPIs: Completeness (required and recommended attributes populated), Compliance (CIs pass Desired State audits), and Correctness (duplicates, orphans, and staleness). These three 'C' scorecards roll up into an overall health score.
2Within the Completeness KPI on the CMDB Health Dashboard, how are required attributes distinguished from recommended attributes?
A.Both are defined only in CI Class Manager with a priority flag
B.Required attributes come from Discovery while recommended come from manual entry
C.Required attributes are defined in the System Dictionary as mandatory, while recommended attributes are configured in CI Class Manager
D.Required attributes are encrypted while recommended attributes are plain text
Explanation: Completeness aggregates two sub-metrics: required attributes (fields marked mandatory in the System Dictionary, sys_dictionary) and recommended attributes (fields flagged as recommended in CI Class Manager). A CI is incomplete if any required or recommended attribute is empty.
3The Correctness KPI flags a CI as stale. By default, after how many days without an update does the base staleness rule consider a CI stale?
A.7 days
B.30 days
C.60 days
D.90 days
Explanation: The default staleness rule in the Correctness scorecard marks a CI as stale when it has not been updated within 60 days. Administrators can adjust this threshold, but 60 days is the out-of-box default used to flag potentially abandoned or no-longer-discovered CIs.
4Which Correctness sub-metric requires you to manually configure rules because the base system ships with none defined?
A.Duplicate CIs
B.Stale CIs
C.Required attributes
D.Orphan CIs
Explanation: Orphan rules identify CIs that lack expected relationships, but ServiceNow ships no out-of-box orphan rules, so administrators must define them for each relevant class. Duplicates leverage identification rules and staleness uses the default rule, but orphans must be configured before they contribute to the Correctness score.
5How does the current CMDB Health Dashboard calculate a KPI score for a given metric?
A.As the number of passing CIs multiplied by a fixed weight
B.As the average age of all CIs in the class
C.As the ratio of failed CIs to total CIs across the included sub-metrics
D.As the count of CIs created in the last 24 hours
Explanation: The redesigned CMDB Health Dashboard computes each KPI score as the ratio of all failed CIs across its sub-metrics to the total CIs evaluated by those sub-metrics. Administrators can choose which metrics are included and assign weights to each in the aggregation.
6The Compliance KPI on the CMDB Health Dashboard primarily evaluates whether CIs conform to what?
A.The number of inbound relationships
B.Their most recent discovery timestamp
C.Their Desired State audit definitions
D.The sys_object_source record count
Explanation: Compliance measures whether CIs pass Desired State audits, which check that attribute values match the configuration standards an organization has defined. A CI failing its Desired State audit lowers the Compliance score for its class.
7The CMDB Data Manager replaces which legacy capability for governing the lifecycle of CI records through policy-driven actions?
A.Update Sets
B.Data Certification
C.Schema Map
D.Field Normalization
Explanation: CMDB Data Manager is the policy-driven platform that supersedes the legacy Data Certification feature. It governs CI lifecycle through scheduled policies that retire, archive, or delete CIs and can attach an attestation workflow for owner verification.
8Which set of lifecycle actions can a CMDB Data Manager policy execute on configuration items?
A.Retire, Archive, and Delete
B.Discover, Map, and Normalize
C.Approve, Reject, and Escalate
D.Encrypt, Mask, and Export
Explanation: CMDB Data Manager policies drive CIs through end-of-life actions: Retire (sets the CI status to retired), Archive (moves the record into archive tables as read-only), and Delete (permanently removes it). Policies can also require attestation before an action proceeds.
9When a CMDB Data Manager policy archives a CI, where does the record go?
A.It is permanently deleted with no recovery
B.It is moved to read-only archive tables and removed from the active cmdb_ci table
C.It stays in cmdb_ci but is hidden from lists
D.It is copied to an Import Set staging table
Explanation: The Archive action moves the CI out of the active cmdb_ci hierarchy into read-only archive tables, preserving the record and its relationships for audit without keeping it in operational data. This differs from Delete, which removes the record permanently.
10A CMDB Data Manager policy can require an attestation step before executing a lifecycle action. What is the purpose of attestation?
A.To have a responsible owner verify the CI's status before the action proceeds
B.To encrypt the CI before deletion
C.To automatically rediscover the CI
D.To duplicate the CI for backup
Explanation: Attestation is an optional Data Manager workflow that asks the CI owner or other responsible party to confirm the CI's state before a lifecycle action such as retire or delete is carried out. This adds human governance so records are not removed in error.

About the Data Foundations (CMDB and CSDM) Exam

The CIS-DF exam validates an implementer's ability to build and govern a trusted ServiceNow CMDB using the Common Service Data Model (CSDM). It covers CMDB Health (Completeness, Compliance, and Correctness), CMDB Data Manager lifecycle governance, the Identification and Reconciliation Engine (IRE) with its identification and reconciliation rules, ingestion through Service Graph Connectors and multisource CMDB, CI Class Manager configuration, and CSDM service modeling. The blueprint is organized into five weighted domains: Governance (35%), Insight (20%), Ingestion (19%), Configuration (15%), and CSDM Fundamentals (11%). Candidates should have hands-on CMDB and CSDM experience and complete the ServiceNow University Data Foundations learning path before testing.

Data Foundations (CMDB and CSDM) Exam Content Outline

35%

Governance

Govern CMDB data quality with the CMDB Health dashboard (Completeness from required and recommended attributes, Compliance from Desired State audits, and Correctness from duplicates, orphans, and the 60-day staleness rule). Apply CMDB Data Manager policies for retire, archive, delete, and attestation; manage CSDM lifecycle_stage governance; and remediate duplicate CIs.

20%

Insight

Use CMDB Query Builder for multi-class, relationship-aware queries and the Unified Map (combining Dependency Views and Service Mapping) for top-down dependency visualization. Drive impact analysis and service-aware reporting from accurate CMDB relationships.

19%

Ingestion

Route all CI writes through the Identification and Reconciliation Engine (IRE) so identification rules match or create CIs and reconciliation rules set data source precedence. Ingest with Service Graph Connectors over custom Import Sets, handle partial payloads, and use multisource CMDB (CMDB 360) for field-level source tracking and reversion.

15%

Configuration

Configure the CMDB in CI Class Manager: class hierarchy and table inheritance from cmdb_ci, attribute design, relationship rules, and authoring identification rules (with prioritized identifier entries and dependent entries) and reconciliation rules. Prefer extending out-of-box classes and choosing stable identifiers like serial number.

11%

CSDM Fundamentals

Apply the Common Service Data Model's five domains (Foundation, Design, Build, Manage Technical Services, Sell/Consume), align CIs to the correct classes, and model services correctly, distinguishing Business Applications from operational Application Services and pairing Business Services with Service Offerings.

Data Foundations (CMDB and CSDM) Study Tips from Top Performers

1Master the three CMDB Health KPIs: Completeness (required from the System Dictionary, recommended from CI Class Manager), Compliance (Desired State audits), and Correctness (duplicates, orphans, and the default 60-day staleness rule).
2Be able to distinguish CMDB Data Manager lifecycle actions: Retire changes status, Archive moves records to read-only archive tables, Delete removes permanently, and attestation adds owner verification.
3Drill the IRE order of operations: identification rules match or create the CI first, then reconciliation rules decide which data source may write the values, including how ambiguous multi-CI matches raise an error instead of merging.
4Know CI Class Manager deeply: table inheritance from cmdb_ci, attribute design, prioritized identifier entries, dependent identifier entries, and why stable identifiers like serial number beat volatile ones like IP address.
5Memorize the five CSDM domains (Foundation, Design, Build, Manage Technical Services, Sell/Consume) and the Business Application versus Application Service distinction, plus lifecycle_stage and lifecycle_stage_status.
6Practice ingestion best practices: prefer Service Graph Connectors over custom Import Sets, route all writes through the IRE, and use multisource CMDB (CMDB 360) for field-level source tracking and reversion.

Frequently Asked Questions

What are the current exam facts for CIS-DF?

ServiceNow's CIS-DF Data Foundations (CMDB and CSDM) exam is delivered online proctored with about 60 multiple-choice and multiple-select questions in 90 minutes and a passing score near 70%. The fee is $225 USD, but the first attempt is free through June 30, 2026.

What does the CIS-DF exam cover?

CIS-DF tests five weighted domains: Governance (35%), Insight (20%), Ingestion (19%), Configuration (15%), and CSDM Fundamentals (11%). Core topics include CMDB Health, CMDB Data Manager, the IRE, identification and reconciliation rules, CI Class Manager, and the Common Service Data Model.

Which domain carries the most weight on CIS-DF?

Governance is the largest domain at 35%, covering the CMDB Health dashboard (Completeness, Compliance, Correctness), CMDB Data Manager lifecycle actions, CSDM lifecycle governance, and duplicate handling and remediation.

What is the difference between identification rules and reconciliation rules?

Identification rules let the IRE determine whether an incoming payload matches an existing CI (update) or needs a new CI (create). Reconciliation rules set data source precedence so only the authoritative source can update a given class or attribute when multiple sources conflict.

What are the three CMDB Health KPIs?

The CMDB Health dashboard scores Completeness (required and recommended attributes populated), Compliance (CIs pass Desired State audits), and Correctness (duplicates, orphans, and staleness, with a default 60-day staleness rule). These three Cs roll up into an overall health score.

Is the CIS-DF exam really free in 2026?

ServiceNow is offering the first CIS-DF attempt free through June 30, 2026. After that, or for any retake, the exam costs $225 USD. Confirm the latest offer and blueprint on the ServiceNow University page before scheduling.
