CIS-DF Practice Test 19 — 15 Questions

Question 1

Which THREE of the following mechanisms can be used to populate or maintain Application Services in the CMDB?

Accepted Answer

Manual CI selection and list management. Option A (Manual CI selection and list management) is correct because Application Services in the CMDB can be populated by manually adding CIs to the service record, giving administrators direct control over which configuration items belong to the service. Option B (Dynamic CI Groups using query criteria) is correct because Application Services can be maintained dynamically through CI Groups whose membership is defined by query conditions, so CIs are automatically included or excluded as they match or fail the criteria. Option E (Top-down Service Mapping) is correct because Service Mapping discovers and builds Application Services by tracing traffic and dependencies top-down from an entry point, automatically creating and maintaining the service CIs and their relationships in the CMDB. Option C is not correct because incident ticket attachments are unstructured data and are not a supported mechanism for populating CMDB Application Services. Option D is not correct because Foundation user records are identity/user data, not CI records, and are not automatically converted into Application Services.

Answer

Direct import of incident ticket attachments

Answer

Automatic conversion of Foundation user records

Question 2

An organization notices that custom application CIs are failing compliance checks because the governance policy checks standard fields that do not apply to custom apps. How should an administrator resolve this while maintaining governance standards?

Accepted Answer

Create a class-specific governance policy targeting the custom application table. ServiceNow CMDB Data Governance policies are applied per CI class, so the correct fix is to create a class-specific governance policy that targets the custom application table (a child of cmdb_ci_appl) and defines only the fields relevant to that class. This preserves governance for standard CIs while allowing custom apps to be evaluated against appropriate rules. It maintains compliance standards rather than bypassing them.

Answer

Disable CMDB Data Governance globally

Answer

Add mandatory fields to the base configuration item table (cmdb_ci)

Answer

Ignore the failed tasks permanently

Question 3

An organization wants to configure CMDB Data Governance remediation tasks so that when a completeness policy fails for a high-priority server, a task is automatically assigned to the data owner. Where are these remediation workflows and task generation parameters configured?

Accepted Answer

CMDB Data Governance > Policies. CMDB Data Governance > Policies is where administrators define the health policies (completeness, correctness, compliance, duplicates) and configure the remediation workflow, task assignment rules, and task generation parameters such as the assignee (data owner), priority, and due date. The policy record itself contains the 'Remediation' related list and task generation settings that drive automatic task creation when a high-priority server fails the completeness check.

Answer

CMDB Health > Dashboard Settings

Answer

Data Certification > Definitions

Answer

System Policy > Rules > Data Policy

Question 4

An integration script is passing a complex payload containing multiple related CIs to the Identification and Reconciliation Engine (IRE) via the script include 'JSONUtils' or 'CmdbUtil'. Which payload structure is required for the IRE to correctly process related CIs in a single transaction?

Accepted Answer

A root object containing an 'items' array for the CIs and a 'relations' array specifying parent, child, and relationship type references.. The IRE payload requires a structured JSON object containing an 'items' array for the CIs and a 'relations' array to define relationships between items in the payload.

Answer

Separate REST API calls for each CI followed by a manual relationship creation call.

Answer

A CSV file attached to a Data Source record processed exclusively by a Transform Map.

Answer

A flat array of CI records with parent and child reference ID fields embedded directly in each CI record.

Question 5

An administrator needs to create a CMDB Query Builder definition to locate all Windows Servers that host a specific Business Application and have an open critical Incident. What capability does Query Builder provide to achieve this?

Accepted Answer

Visual graphical querying across multiple related CMDB tables and operational tables. Query Builder allows users to construct visual multi-table graph queries across the CMDB and related operational tables (such as Incidents) without writing complex SQL or scripted GlideRecord queries.

Answer

Real-time execution of automated remediation workflows on matching CIs

Answer

Automatic conversion of query results into scheduled Discovery jobs

Answer

Enforcement of CI write-access restrictions during query execution

Question 6

Your organization is designing a custom subclass for specialized network appliances that require unique attributes not found in the standard cmdb_ci_netgear class. When creating a custom CI class extending cmdb_ci, what is the best practice recommendation regarding table extension?

Accepted Answer

Extend from the most specific existing parent class that shares the common attributes of the new CI type.. ServiceNow best practice for creating custom CI classes is to extend from the most specific existing parent class that already shares the common attributes of the new CI type. This maximizes inheritance of relevant fields, relationships, and behaviors while avoiding duplication, and keeps the custom class properly positioned within the CMDB class hierarchy for reporting and CSDM alignment.

Answer

Create a standalone table independent of the CMDB hierarchy and link it via business rules.

Answer

Extend from cmdb_rel_ci to automatically inherit relationship capabilities.

Answer

Always extend directly from cmdb to avoid table bloat and performance degradation.

Question 7

An administrator needs to track overall CMDB data quality using standardized metrics out of the box. Which specific dashboard should they access in ServiceNow to view scores for Completeness, Correctness, Compliance, and Freshness?

Accepted Answer

CMDB Health Dashboard. The CMDB Health Dashboard provides out-of-the-box scores for Completeness, Correctness, Compliance, and Freshness to help administrators measure data quality.

Answer

CSDM Framework Dashboard

Answer

Data Certification Dashboard

Answer

CI Class Manager Dashboard

Question 8

Which THREE features are provided natively by the CMDB Query Builder tool? (Choose three.)

Accepted Answer

Exporting query results to JSON or CSV formats. Option C is correct because the CMDB Query Builder natively supports exporting query results to JSON or CSV formats, allowing administrators to extract and share CMDB data for reporting or external processing. Option D is correct because the tool lets users filter nodes by specific CI attributes and by related task states, enabling targeted queries that combine configuration item data with workflow/task context. Option E is correct because CMDB Query Builder provides a visual, drag-and-drop interface for constructing multi-class relationship queries, so users can traverse relationships across multiple CI classes without writing SQL. Options A and B are not native features: the Query Builder is a querying and reporting tool and does not generate automated remediation workflows in real time, nor does it perform direct packet capture analysis for discovered network switches.

Answer

Real-time generation of automated remediation workflows

Answer

Direct packet capture analysis for discovered network switches

Question 9

An IT architect wants to map a Software-as-a-Service (SaaS) application (e.g., Workday) into the CSDM framework. Since there is no on-premise infrastructure to discover, how should Workday be modeled?

Accepted Answer

As a Business Application record linked to an Application Service record representing the SaaS tenant, without requiring local infrastructure CIs.. A SaaS application like Workday has no on-premise infrastructure to discover, so CSDM models it as a Business Application (the logical application the business uses) linked to an Application Service that represents the SaaS tenant/instance. No local infrastructure CIs are required because the underlying infrastructure is owned by the SaaS provider and is out of scope for the CMDB. This is the standard CSDM pattern for SaaS in the Design domain.

Answer

As a Technical Service with no portfolio parent.

Answer

As an unmapped Incident record.

Answer

As a Hardware Asset CI in the Foundation domain.

Question 10

An organization uses ServiceNow Discovery to populate servers. They also have a security vulnerability scanner that ingests vulnerability records and associates them with CIs in the CMDB. The security tool frequently sends payloads containing stale IP addresses that match existing CIs incorrectly because the IP reuse policy in their network causes IP addresses to cycle rapidly. How can the administrator prevent the security tool from using IP address as an identification criterion while still allowing it to update vulnerability attributes?

Accepted Answer

Review and refine the identification rules for the server class to remove volatile attributes like IP address, ensuring identification relies on stable unique keys like serial number or system ID.. The administrator should refine the identification rules for the server class to remove volatile attributes like IP address. By ensuring identification relies on stable unique keys such as serial number or system ID, the security tool can still update vulnerability attributes without incorrectly matching CIs based on IP.

Answer

Configure Data Source Precedence to block the security tool from updating IP addresses.

Answer

Write a Business Rule on cmdb_ci to delete IP records when IP churn occurs.

Answer

Set the security tool's discovery source to 'Manual'.

Question 11

An administrator is reviewing the Correctness score on the CMDB Health Dashboard and notices a low score caused by multiple CIs having no relationships to any business services. Which specific Correctness metric is flagging this issue?

Accepted Answer

Orphans. The Orphans metric under CMDB Health Correctness flags CIs that have no relationships to any business services or other CIs, indicating they are disconnected from the service model. A low Correctness score caused by CIs lacking business-service relationships is precisely what the Orphans KPI measures. This helps identify CIs that need to be related or retired.

Answer

Duplicate CIs

Answer

Unassigned CIs

Answer

Stale CIs

Question 12

An organization is utilizing CSDM (Common Service Data Model) and needs to relate technical CIs to business services and applications. Which THREE relationship types or foundational concepts are core to proper CSDM alignment in the CMDB? (Choose three.)

Accepted Answer

Relating Business Applications to Application Services using the 'Consumes::Consumed by' or instance relationship mappings.. Option B is correct because CSDM models the relationship between a Business Application and the Application Service(s) that realize it, typically via 'Consumes::Consumed by' or the application service instance relationship, which links the logical business-facing layer to the technical service layer. Option C is correct because CSDM is organized into distinct domains — Design (business/application models), Technical (infrastructure and technical services), and Sell/Consume (service offerings and subscriptions) — and clear demarcation between these domains is foundational to aligning CIs correctly. Option D is correct because infrastructure CIs (servers, databases, etc.) must be connected to Application Services through relationships such as 'Hosted on::Hosts' or 'Depends on::Used by' to trace technical components up to the services they support. Option A is incorrect because CSDM requires differentiated CI classes (e.g., cmdb_ci_business_app, cmdb_ci_appl, cmdb_ci_server) rather than a single flat table, which would destroy class hierarchy and relationship semantics. Option E is incorrect because relationships in the CMDB are stored in dedicated relationship tables (e.g., cmdb_rel_ci) via CI Relationship [cmdb_rel_ci], not in the task table, which is used for work items like incidents, changes, and problems.

Answer

Storing all users, business applications, and servers in a single flat cmdb_ci table without differentiation.

Answer

Using the task table to store direct relationships between hardware and software.

Question 13

Which of the following domains is responsible for managing technical infrastructure, hardware, and software instances?

Accepted Answer

Manage Technical Services. The Manage Technical Services domain in the ServiceNow CIS-Data Foundation (CIS-DF) certification covers the operational management of technical infrastructure, including hardware, software instances, and configuration items (CIs). It focuses on the processes and tools used to monitor, maintain, and support the technical components that underpin IT services. This domain ensures that the technical foundation is effectively managed throughout its lifecycle, aligning with ITIL practices for technical service management.

Answer

Sell/Consume

Answer

Foundation

Answer

Design

Question 14

An administrator needs to deprecate an old custom CI class that is no longer in use. What is the recommended best practice in the CI Class Manager?

Accepted Answer

Use the CI Class Manager to deprecate or safely review dependent records and rules before taking action.. The CI Class Manager provides a safe, guided way to deprecate or delete a custom CI class, including checks for dependent records, identification rules, and relationships before action is taken. Best practice is to use this tool to review dependencies and deprecate the class rather than deleting it outright, preserving data integrity and audit history.

Answer

Delete the table directly from the Tables and Columns module without checking for records.

Answer

Deactivate all identification rules and leave the table orphaned.

Answer

Rename the table name prefix to 'z_deprecated_' directly in the dictionary.

Question 15

Your company acquires another firm and inherits two separate ServiceNow instances. You are consolidating them and need to merge overlapping Business Applications. When retiring a redundant Business Application record that has active Application Services attached to it, what must be done first according to CSDM data integrity standards?

Accepted Answer

Reassign or re-map the active Application Services to the surviving Business Application record.. According to CSDM data integrity standards, before retiring a Business Application that has active Application Services attached, you must reassign or re-map those Application Services to the surviving Business Application record. This preserves the service hierarchy and prevents orphaned Application Services that would break impact analysis and reporting.

Answer

Export all incident history to an external data lake and delete the CMDB table.

Answer

Convert the redundant Business Application into a Technical Service.

Answer

Delete all underlying infrastructure CIs associated with the application.
