A CMDB Administrator needs to create a new CI class for an Internet of Things (IoT) Sensor in ServiceNow.
What are the recommended practices for this activity?
Creating new CI classes is a high-impact configuration activity and must follow strict Data Foundations and CSDM-aligned best practices to avoid long-term technical debt and upgrade risk.
Option B is a recommended first step. Before creating any new CI class, administrators should install or update the CMDB CI Class Models Store application and verify whether an appropriate class already exists. ServiceNow frequently delivers new CI classes through updates and class model packages, and duplicating an existing or planned class can lead to fragmentation and governance issues.
Option C is also correct. When a new class is truly required, it should be added under an appropriate parent class to inherit attributes, behaviors, and discovery patterns. For an IoT Sensor, this might be under a hardware or device-related parent class, ensuring consistency and minimizing customization.
Option A is incorrect and dangerous---deleting unused classes can break dependencies and historical data. Option D is also discouraged; modifying existing classes to repurpose them violates upgrade-safe design principles and can negatively impact discovery, integrations, and reporting.
By verifying existing models first and extending the class hierarchy correctly, organizations maintain a clean, scalable, and upgrade-safe CMDB.
Therefore, the correct answers are B and C.
With CMDB 360 / Multisource CMDB, Dynamic Reconciliation Rules are enabled. Based on management requirements, a CMDB Administrator needs to configure multiple Dynamic Reconciliation Rules.
Which are available Dynamic Rule Types within the Create Reconciliation Rule wizard? (Choose 2 options)
CMDB 360 / Multisource CMDB extends the standard IRE by enabling Dynamic Reconciliation Rules, which determine attribute values dynamically based on incoming data patterns rather than fixed source priority.
Within the Create Reconciliation Rule wizard, two supported dynamic rule types are:
Most Reported (Option B): selects the attribute value that is reported most frequently across all sources. This is useful when multiple sources contribute data and consensus is a strong indicator of correctness.
Last Updated (Option C): selects the most recently updated value, which is useful for rapidly changing attributes such as IP address or operational state.
Option A (Smallest Value) and Option D (Last Created) are not supported dynamic reconciliation rule types in ServiceNow.
Dynamic reconciliation rules are particularly valuable in complex, multisource environments where rigid source precedence is insufficient and data confidence must be inferred.
Therefore, the correct answers are B -- Most Reported and C -- Last Updated.

Configuration Management needs to ensure data quality for all CIs in the CMDB.
What areas of data quality for CIs are included in the CMDB Health Dashboard?
The CMDB Health Dashboard is a central component of CMDB Data Foundations insight and governance. It measures and tracks data quality using well-defined health indicators that focus on the accuracy, relevance, and usability of CI data.
Two key data quality areas included in the dashboard are Stale CIs and Duplicate CIs.
Stale CIs (Option D) refer to configuration items that have not been updated within a defined time window. These records are risky because they may no longer reflect the current state of the environment, leading to inaccurate impact analysis, poor change decisions, and misrouted incidents. Monitoring staleness helps organizations identify where discovery, integrations, or ownership processes are failing.
Duplicate CIs (Option E) occur when the same real-world asset or service is represented by multiple records. Duplicates undermine trust in the CMDB, distort reporting, and break service mappings. The CMDB Health Dashboard highlights duplicate trends and integrates with de-duplication and remediation workflows to address them.
Options A (Downgraded CIs), B (Upgraded CIs), and C (Missing CIs) are not standard CMDB Health Dashboard quality dimensions. While ''missing'' data may be inferred through completeness checks, Missing CIs as a category is not directly tracked.
Therefore, the correct answers are D -- Stale CIs and E -- Duplicate CIs, which are core CMDB Health indicators used to maintain high-quality configuration data.
A Configuration Manager is planning the implementation of the CMDB.
Which is the prescribed CSDM rollout order?
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.
According to the Common Service Data Model (CSDM), a server team is requesting a catalog item be created for infrastructure requests.
Which role is involved in initiating the request and defining requirements?
In CSDM, Technology Services (and their Service Offerings) represent how technical capabilities are delivered and consumed by internal teams. When a server team requests a catalog item for infrastructure services (e.g., VM provisioning, storage, OS builds), the role responsible for initiating the request and defining requirements is the Technology Service Owner.
Technology Service Owners understand the operational capabilities, constraints, SLAs, and fulfillment workflows required to deliver infrastructure services. They define catalog requirements such as options, approvals, fulfillment tasks, and guardrails---ensuring the request aligns with standardization, security, and operational readiness.
Application Service Owners focus on how applications are delivered and supported, not on defining infrastructure catalog items. Enterprise Architects provide standards and guidance but do not initiate or define catalog request requirements.
Thus, the correct role is B -- Technology Service Owners.
