CIS-DF Practice Test 12 — 15 Questions

Question 1

Which CSDM domain covers the definition and management of Technical Services that support internal IT operations?

Accepted Answer

Manage Technical Services. The Manage Technical Services domain in the CSDM (Common Service Data Model) framework covers the definition and management of Technical Services that support internal IT operations. It sits between the Design and Sell/Consume domains and provides the operational layer for how IT services are delivered and maintained. This domain includes Technical Service, Technical Service Offering, and related CIs used by IT operations.

Answer

Design

Answer

Foundation

Answer

Sell/Consume

Question 2

Your enterprise has implemented CSDM, but incident managers report that problem investigation is slowed because problem records are linked to Business Applications instead of Application Services. Why does linking problems to Application Services improve investigation efficiency?

Accepted Answer

Application Services provide the specific deployment and runtime infrastructure context needed to trace hardware and software component failures.. Application Services provide the specific deployment and runtime infrastructure context — the servers, databases, middleware, and network components — that a problem analyst needs to trace hardware and software component failures. Business Applications are logical groupings that do not carry this low-level infrastructure detail, so linking problems to Application Services gives investigators a direct path to the failing components. This is why CSDM recommends associating problems with Application Services rather than Business Applications.

Answer

Problem records cannot be saved unless an Application Service is populated.

Answer

Application Services automatically generate patch scripts for problem analysts.

Answer

Business Applications automatically reject problem records that lack an assigned change advisory board.

Question 3

An organization wants to publish a service catalog item for 'New Laptop Request'. Which CSDM domain governs the catalog item and the associated Service Offering?

Accepted Answer

Sell/Consume. The Sell/Consume domain in CSDM governs the commercial and consumption layer — Service Offerings, Catalog Items, Demand, and Service Consumption. A 'New Laptop Request' catalog item and its associated Service Offering are exactly the entities modeled in Sell/Consume, which represents what the business offers to consumers and how they request it. This domain sits above Design and Manage Technical Services, translating technical services into consumable offerings.

Answer

Design

Answer

Manage Technical Services

Answer

Foundation

Question 4

Which TWO metrics are standard components of the CMDB Health Dashboard overview? (Choose two.)

Accepted Answer

Correctness score. The CMDB Health Dashboard in ServiceNow is built around three standard health metrics: Correctness, Completeness, and Compliance. Option C (Correctness score) is correct because it measures whether CI records have accurate, valid data — for example, CIs that fail validation against CI class rules or have duplicate records — and it appears as a core KPI tile on the dashboard overview. Option E (Completeness score) is correct because it measures whether required CI attributes and relationships are populated, such as missing mandatory fields or missing related CIs, and it is likewise a standard dashboard component. The other options do not belong: Network latency (A) is a performance/availability metric, Help desk ticket backlog (B) is an ITSM incident/request metric, and Employee satisfaction (D) is a survey/CSAT metric — none of these are CMDB health metrics in the dashboard.

Answer

Network latency score

Answer

Help desk ticket backlog score

Answer

Employee satisfaction score

Question 5

An administrator is troubleshooting missing relationship data after running a custom data integration. Which THREE of the following factors should be investigated? (Choose three.)

Accepted Answer

Whether the payload structure correctly formats the related items or relationship blocks required by the IRE.. Option A is correct because the Identification and Reconciliation Engine (IRE) requires the payload to include properly formatted related items or relationship blocks; if the structure is malformed, the IRE cannot create the relationships. Option C is correct because both the source and target CIs in a relationship payload must successfully pass identification; if either CI fails to identify or be created, the relationship cannot be established. Option D is correct because the relationship type (for example, 'Runs on::Runs') must exist and be active in the cmdb_rel_type table, otherwise the IRE will reject or skip the relationship. Option B is not correct because client scripts on the target CI table do not block IRE relationship processing, which operates at the server/API level. Option E is not correct because the Discovery status schedule setting is unrelated to custom data integration relationship handling.

Answer

Whether the target CI table has active client scripts blocking the relationship field.

Answer

Whether the Discovery status schedule is set to 'Quick Discovery'.

Question 6

Where can an administrator view graphical relationship maps directly from an incident ticket to assess which business services might be affected by an attached configuration item?

Accepted Answer

Dependency Views icon next to the Configuration Item field. The CI field on an incident record includes a preview icon and link to open Dependency Views.

Answer

CI Class Manager relationship tab

Answer

Business Service Catalog

Answer

CMDB Data Manager policy list

Question 7

Which TWO of the following fields are typically found on a Business Application record in the Design domain?

Accepted Answer

Vendor [vendor]. Option B (Vendor) is correct because a Business Application record in the Design domain captures ownership and support information, including the software vendor or publisher that supplies the application. Option D (Business criticality) is correct because the Design domain records how important the application is to the business (for example, critical, high, medium, or low), which drives impact analysis and prioritization. Options A (IP address) and E (MAC address) are incorrect because these are network-layer identifiers that belong to infrastructure or configuration item records (such as servers or network devices), not to a business application definition. Option C (BIOS serial number) is incorrect because it is a hardware asset identifier tied to a physical device, not an attribute of a business application.

Answer

IP address [ip_address]

Answer

BIOS serial number [serial_number]

Answer

MAC address [mac_address]

Question 8

Your team is troubleshooting a business service mapping issue where incident impact analysis fails to show downstream application outages. Upon reviewing the CMDB, you discover that the Application Service was created as a 'Manual' type, but its supporting infrastructure CIs were deleted during a data purge. What is the recommended way to restore the mapping?

Accepted Answer

Re-establish the infrastructure CIs and manually re-add them to the Application Service via the Application Service Workbench.. Manual Application Services do not auto-populate relationships from discovery; their CIs must be added by hand. Once the supporting infrastructure CIs are restored in the CMDB, the correct remediation is to re-add them to the Application Service through the Application Service Workbench, which is the supported UI for managing manual service mappings. This restores the downstream dependency chain so incident impact analysis can traverse it again.

Answer

Run a quick discovery scan to automatically regenerate the manual application service relationships.

Answer

Convert the manual Application Service into a Business Application record.

Answer

Delete the Business Application and recreate it as a Technical Service.

Question 9

An administrator is designing identification rules for a custom CI class in the CMDB. Which THREE ofg the following best practices should be followed when configuring identification rules? (Choose three.)

Accepted Answer

Use attributes that are guaranteed to be unique and immutable, such as serial numbers or hardware asset tags.. Option A is correct because identification rules must rely on attributes that are unique and immutable, such as serial numbers or hardware asset tags, so the same CI is consistently matched rather than duplicated or misidentified when other fields change. Option B is correct because identification rules are evaluated in order, so placing the most reliable and specific criteria first ensures the strongest match is attempted before broader, less precise rules are considered. Option D is correct because volatile attributes like IP address or hostname alone can change when devices move networks, causing false matches or duplicate CIs; they should be combined with stable identifiers or avoided as sole primary identifiers. Option C is incorrect because custom CI classes should extend cmdb_ci (or an appropriate CMDB base class) to inherit the identification engine behavior and required fields, not be created on unrelated custom tables. Option E is incorrect because cramming every attribute into one compound rule makes identification overly restrictive and brittle, so any single changed attribute breaks the match and creates duplicates.

Answer

Ensure that identification rules are created on custom tables without inheriting from cmdb_ci.

Answer

Configure every single attribute of the CI class into a single compound identification rule entry to ensure maximum security.

Question 10

Which TWO types of metrics are evaluated under the CMDB Health framework? (Choose two.)

Accepted Answer

Correctness. Under the CMDB Health framework, Correctness (C) is evaluated because it measures whether CI records contain accurate and valid data, such as ensuring required fields have valid values and that CIs conform to their class definitions. Completeness (D) is also evaluated because it measures whether required attributes and relationships are populated for each CI, identifying records that are missing mandatory data. These two metrics are part of the standard CMDB Health KPIs, along with compliance and duplicate metrics. Availability (A), Scalability (B), and Performance (E) are not CMDB Health metric types; they are operational or infrastructure characteristics rather than data-quality dimensions assessed by the CMDB Health framework.

Answer

Availability

Answer

Scalability

Answer

Performance

Question 11

Which THREE of the following actions help ensure accurate relationship-based insights in the CMDB? (Choose three.)

Accepted Answer

Configuring proper IRE identification rules for relationships to prevent duplicate links. Option B is correct because the Identification and Reconciliation Engine (IRE) uses relationship identification rules to determine whether a relationship already exists, so properly configured rules prevent duplicate or conflicting links that would distort relationship-based insights. Option C is correct because Discovery and Service Mapping automatically populate runtime relationships (for example, Service Mapping builds application service dependencies and Discovery populates CI-to-CI connections), giving the CMDB accurate, current topology data instead of relying on manual entry. Option E is correct because the CMDB Health Dashboard surfaces orphan CIs (CIs with no relationships), and monitoring and remediating them restores the missing links that relationship-based analytics depend on. Option A is not appropriate because disabling all manual relationship creation instance-wide removes a legitimate data source and does not by itself improve accuracy. Option D is not appropriate because setting CMDB Query Builder cache timeouts to zero only affects query caching performance, not the accuracy of stored relationships.

Answer

Disabling all manual relationship creation across the entire instance

Answer

Setting CMDB Query Builder cache timeouts to zero

Question 12

Which THREE of the following are benefits of implementing CSDM and using the CSDM Data Foundations Dashboard? (Choose three.)

Accepted Answer

Standardizing service data structures across the enterprise. Option B is correct because the Common Service Data Model (CSDM) provides a standardized set of service-related tables, relationships, and definitions (Business Service, Service Offering, Application Service, etc.) that let organizations model services consistently across the enterprise, eliminating divergent data structures. Option C is correct because that standardized structure aligns the service data used by Incident, Change, and portfolio reporting, so records reference the same service hierarchy and reporting becomes consistent and comparable. Option D is correct because the CSDM Data Foundations Dashboard is specifically designed to surface data gaps and completeness across the CSDM stages — Foundations, Design, Manage, and Sell/Consume — helping teams remediate missing or misaligned records. Option A is not correct because hardware financial depreciation is handled by asset management/financial modules, not by CSDM or its dashboard. Option E is not correct because IP router and switch discovery is performed by Discovery/Service Graph Connectors, not by CSDM or the Data Foundations Dashboard.

Answer

Automating hardware asset financial depreciation calculations

Answer

Automatically discovering IP routers and switches on enterprise networks

Question 13

An administrator is configuring Data Source Precedence rules to manage attribute updates from multiple integrations. Which THREE of the following statements about Data Source Precedence are accurate? (Choose three.)

Accepted Answer

Precedence rules can be configured to allow specific data sources to update designated attributes while blocking others.. Option B is correct because Data Source Precedence rules are designed to control which data sources are authorized to update specific attributes on a record, so an administrator can permit one integration to write certain fields while preventing others from overwriting them. Option D is correct because precedence rules defined on a parent class are inherited by child classes through the class hierarchy, unless the child class has its own explicitly defined rule that overrides the inherited behavior. Option E is correct because when no attribute-level precedence rule exists, the Identification and Reconciliation Engine (IRE) applies its default precedence logic rather than blocking the update outright. Option A is incorrect because Data Source Precedence rules are configured in the Data Source Precedence module/table (e.g., sys_data_source_precedence), not in the System Log (syslog) table, which records system events. Option C is incorrect because legacy transform maps that bypass the IRE do not automatically honor Data Source Precedence rules; those rules are enforced through the IRE reconciliation process.

Answer

Data Source Precedence rules are managed directly within the System Log table.

Answer

Precedence rules automatically apply to legacy transform maps that do not use the IRE.

Question 14

When setting up CMDB data ownership, which field on a CI record is typically used to designate the individual accountable for the physical or logical asset's data quality?

Accepted Answer

Managed by. The 'Managed by' field on a CI record designates the individual accountable for the physical or logical asset's data quality. It is used to assign ownership and responsibility for maintaining accurate information about the CI. This field is typically populated with a user reference and is distinct from fields like 'Caller ID' or 'Reported by', which are used in incident or request contexts.

Answer

Caller ID

Answer

Reported by

Answer

Opened by

Question 15

What is the primary purpose of the CSDM framework in ServiceNow?

Accepted Answer

To provide a standardized product-agnostic data model for mapping services, applications, and infrastructure in the CMDB.. The Common Service Data Model (CSDM) is a standardized, product-agnostic data model that defines how services, applications, business capabilities, and infrastructure are represented and related in the CMDB. It provides prescriptive tables, relationships, and domain separation so that ServiceNow products (ITSM, ITOM, CSM, etc.) share a consistent foundation. Its purpose is data consistency and interoperability, not process replacement or credential automation.

Answer

To replace standard ITIL v4 processes with automated scripts.

Answer

To automatically configure Discovery credentials across network routers.

Answer

To enforce strict password complexity rules for end users.
