ServiceNow Updated CIS-DF Exam Questions and Answers by macie

The correct answer is Service Delivery . In CSDM, the Service Delivery domain focuses on how services are technically delivered and operated. It includes the modeling of technical services, technical service offerings, application services, infrastructure CIs, and the relationships that connect them. The scenario specifically asks about Infrastructure CIs, Technology Management Offerings, Technical Service Offerings, and Application Services, which are all part of the technical operating model for delivering services. Foundation is used for base reference data such as locations, groups, companies, and users. Design and Planning focuses on business applications, capabilities, and planning artifacts. Service Consumption focuses on how consumers access and consume services. Build and Integration is associated with development and deployment activities. Because the question is about technical service relationships and operational service delivery, Service Delivery is the correct CSDM domain.

The Common Service Data Model (CSDM) prescribes an incremental, maturity-based rollout approach to reduce risk and ensure sustainable adoption. The recommended order is Crawl, Walk, Run, Fly, which aligns implementation effort with increasing organizational capability and value realization.

Crawl focuses on foundational data hygiene: core CI classes, identification rules, reconciliation, basic Discovery ingestion, and CMDB Health basics.

Walk introduces service context, including Business Services, Application Services, and relationships that enable impact analysis for Incident and Change.

Run expands into operational excellence with Service Mapping, service offerings, advanced governance, and process automation.

Fly represents optimization and scale, leveraging analytics, AI/ML, proactive operations, and cross-domain integration (e.g., SecOps, APM, CSM).

This progression ensures teams do not over-model early or introduce complexity before data quality and governance are established. The other options describe generic project lifecycles or organizational categorizations, not the CSDM-recommended adoption path.

Therefore, the correct answer is D – Crawl, Walk, Run, Fly.

Data Foundations emphasizes that “ingest” must produce CMDB data that is standardized, supportable, and upgrade-safe. When introducing custom CIs, the best practice is to reuse the most appropriate existing CI class (or an approved industry-aligned model) and only add what is necessary—this keeps the data model aligned with platform expectations and reduces downstream rework.

Option B supports this directly: the CMDB CI Class Models application is intended to help teams select a suitable existing class rather than inventing new classes unnecessarily. Reusing existing classes improves consistency across integrations, Discovery/Service Mapping patterns, reporting, and CMDB Health rules—reducing technical debt and making future platform upgrades smoother.

Option A is also aligned with best practice when used correctly: once you have the right CI class, extending that class to add additional attributes (new fields) is a standard, upgrade-safe customization approach. It preserves the underlying platform data structures and avoids breaking out-of-box behaviors, identification/reconciliation practices, and CMDB Health evaluations.

Option C is not appropriate because Asset tables serve a different purpose (financial/lifecycle tracking) than CI tables (operational/service context). Mixing CI attributes into Asset classes creates confusion and process misalignment. Option D is strongly discouraged because repurposing and renaming base attributes creates long-term ambiguity, breaks shared semantics, and increases upgrade and maintenance risk.

The correct answer is Business Service Offering and Business Service. In CSDM, the Sell/Consume domain represents how services are presented to and consumed by business users, customers, or consumers. Business Services describe the business-facing services delivered by the organization, while Business Service Offerings represent the specific consumable versions of those services, often differentiated by audience, location, service level, availability, or entitlement. Option A belongs more closely to technical service delivery and management, not Sell/Consume. Option B belongs to Design and Planning, where Business Applications, Business Capabilities, and Information Objects are modeled. Since the question specifically asks for the Sell/Consume domain, the correct tables are Business Service and Business Service Offering.
