CIS-DF Practice Test 4 — 25 Questions

Question 1

An administrator is setting up an IntegrationHub REST step to ingest server data into the CMDB via the IRE. Which TWO components must be properly configured within the IntegrationHub action or script? (Choose two.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Invocation of the IRE API (such as `sn_cmdb.IdentificationEngine`) within the script step.. Option B is correct because ingesting data through the Identification and Reconciliation Engine (IRE) requires the IntegrationHub action or script step to explicitly call the IRE API, typically via the sn_cmdb.IdentificationEngine script include, so the payload is processed by IRE rather than inserted directly. Option E is correct because the IRE expects a properly structured JSON payload containing valid CI class names, identification attributes (such as serial_number, name, or sys_class_name), and related item entries so it can identify, reconcile, and create or update CIs correctly. Option A is not needed because Service Mapping horizontal patterns are used for service discovery topology mapping, not for REST-based CMDB ingestion via IRE. Option C is not needed because Discovery schedules and IP ranges apply to Discovery, not to an IntegrationHub REST step. Option D is not needed because legacy Transform Maps are bypassed when using the IRE API for identification and reconciliation.

Answer

Service Mapping horizontal pattern criteria.

Answer

Discovery schedule IP ranges matching the REST server IP.

Answer

Legacy Transform Map record definitions linked to the REST endpoint.

Question 2

Which TWO statements are true regarding Configuration Item (CI) relationships in ServiceNow? (Choose two.)

Accepted Answer

Relationships are directional, typically defined between a parent CI and a child CI.. Option B is correct because CI relationships in ServiceNow are directional, defined with a parent-child structure (for example, a server 'Contains' an application, or a database 'Depends on' a server), where the relationship type specifies the direction and nature of the link. Option E is correct because all CI-to-CI relationships are stored as records in the cmdb_rel_ci table, which holds the parent, child, and relationship type fields that define each connection. Option A is incorrect because creating a relationship does not delete CIs; relationships are independent records that can be created or removed without affecting the existence of the CIs themselves. Option C is incorrect because a CI can participate in many relationships simultaneously (for example, a server can contain multiple applications and depend on multiple databases). Option D is incorrect because relationships are stored in the cmdb_rel_ci table as separate records linking two CIs, whereas reference fields such as 'Assigned to' are simple field references on a single record and do not create CI-to-CI relationship records.

Answer

Creating a relationship automatically deletes both CIs if one is updated.

Answer

A CI can only participate in a single relationship across the entire CMDB.

Answer

Relationships and reference fields (like 'Assigned to') function in the exact same manner.

Question 3

An organization wants to categorize its applications based on whether they are mission-critical, business-operational, or administrative. Where should this classification be recorded according to CSDM best practices?

Accepted Answer

Business Application [cmdb_ci_business_app]. In CSDM, the Business Application [cmdb_ci_business_app] record is the correct place to capture business-criticality classification (mission-critical, business-operational, administrative) because it represents the logical application from a business perspective. This classification drives prioritization, reporting, and governance decisions tied to the application's business value.

Answer

Incident [incident]

Answer

User [sys_user]

Answer

Application Service [cmdb_ci_service_calculated]

Question 4

Which TWO of the following actions can be performed directly within the CI Class Manager? (Choose two.)

Accepted Answer

Create and modify identification rules for a CI class. The CI Class Manager is the ServiceNow module used to define and maintain the CMDB class model, so option B is correct because it lets you create and modify identification rules (including CI identifiers and reconciliation rules) for a specific CI class directly in that interface. Option C is also correct because the CI Class Manager allows you to add new attributes/fields to a CI class, extending its schema without leaving the class definition UI. Option A is not correct because SLAs for incident resolution are configured in the SLA module (SLA definitions/Workflow), not in CI Class Manager. Option D is not correct because Discovery schedules and network scans are managed in Discovery Schedule/Discovery, not in CI Class Manager. Option E is not correct because graphical multi-table CMDB queries are built with Query Builder/CMDB Query Builder, not within CI Class Manager.

Answer

Configure Service Level Agreements (SLAs) for incident resolution

Answer

Schedule and execute Discovery network scans

Answer

Build graphical multi-table CMDB queries

Question 5

An administrator is troubleshooting a scenario where relationships created between Application Service CIs and underlying Server CIs are disappearing after a Discovery scheduled job runs. Upon reviewing CI class manager settings, which feature or setting most likely caused this behavior due to incorrect payload identification?

Accepted Answer

Identification and Reconciliation Engine (IRE) identification rules and dependent relationship definitions. The Identification and Reconciliation Engine (IRE) uses identification rules to determine which CI a payload corresponds to. If the identification rules are misconfigured, a discovery payload might be incorrectly identified as a different CI, causing existing relationships to be deleted or recreated. Dependent relationship definitions in IRE also control how relationships are maintained during reconciliation; incorrect settings can lead to relationships being removed when they should be preserved.

Answer

Data Dictionary cascade delete settings on the sys_dictionary table

Answer

CMDB Health dashboard completeness scorecards

Answer

Discovery Schedule exclude rules

Question 6

Which THREE actions occur when a Data Certification task is assigned to a CI owner? (Choose three.)

Accepted Answer

The reviewer can update incorrect attribute values directly from the task interface. Option B is correct because the Data Certification task interface lets the assigned CI owner (reviewer) correct inaccurate attribute values directly on the CI record while performing the certification. Option D is correct because the reviewer must submit a certification response (for example, certified or not certified), and that submission completes the task. Option E is correct because the core purpose of assigning a Data Certification task to a CI owner is to have that reviewer verify whether the CI's data is accurate and up to date. Option A is incorrect because certification does not automatically retire a CI; retirement is a separate lifecycle action. Option C is incorrect because Data Certification does not automatically generate a high-priority incident for the service desk.

Answer

The CI is automatically retired from the database immediately

Answer

A high-priority incident is automatically created for the IT service desk

Question 7

Which TWO metrics are tracked out-of-the-box as part of the CMDB Health Dashboard? (Choose two.)

Accepted Answer

Completeness. The CMDB Health Dashboard in ServiceNow tracks three out-of-the-box health metrics: Completeness, Correctness, and Compliance. Option B (Completeness) is correct because the dashboard measures whether required CI attributes and related fields are populated, flagging CIs that are missing mandatory data. Option C (Correctness) is correct because the dashboard evaluates data accuracy by checking for orphan CIs, duplicate CIs, and CIs that fail audit or staleness rules. Options A (Availability), D (Performance), and E (Bandwidth) are not CMDB health metrics; they are operational or infrastructure monitoring metrics tracked by tools such as monitoring agents or network management systems, not by the CMDB Health Dashboard.

Answer

Availability

Answer

Performance

Answer

Bandwidth

Question 8

Where can an administrator view overall metrics regarding CMDB data quality, including completeness, correctness, and compliance?

Accepted Answer

Configuration > CMDB Health Dashboard. The CMDB Health Dashboard, accessed via Configuration > CMDB Health Dashboard, is the dedicated ServiceNow interface that aggregates CMDB data quality metrics across the three core pillars: completeness, correctness, and compliance (plus relationship health and duplicate metrics). It provides KPI scores, drill-downs to failing CIs, and trend visualization specifically for CMDB health.

Answer

System Diagnostics > Stats

Answer

Performance Analytics > Dashboards > CI Quality

Answer

Reports > View/Run > CMDB Quality

Question 9

What does a green health score indicator represent on the CMDB Health Dashboard?

Accepted Answer

The metric meets or exceeds the defined target threshold for data quality.. A green indicator on the CMDB Health Dashboard signifies that the compliance, completeness, or correctness metric meets or exceeds the defined target threshold.

Answer

The CI is currently part of an active Service Map.

Answer

The CI has active Discovery credentials.

Answer

No changes have been made to the CI in 365 days.

Question 10

What is the main benefit of establishing CMDB data stewardship roles within an enterprise?

Accepted Answer

To ensure continuous data quality, accountability, and ownership of CMDB assets. CMDB data stewardship roles establish clear ownership and accountability for CMDB data quality, ensuring that designated stewards maintain accurate, complete, and timely CI records. This governance model is the primary benefit because it assigns responsibility for data integrity across the enterprise.

Answer

To approve all software license purchases

Answer

To write custom JavaScript business rules for system performance

Answer

To manage network switch VLAN configurations

Question 11

What is the primary role of the 'Walk' phase in CSDM maturity?

Accepted Answer

To introduce service portfolios and basic service mapping.. The Walk phase in CSDM maturity is where organizations introduce service portfolios and basic service mapping, moving beyond the foundational Crawl phase. It establishes structured service definitions and begins linking services to CIs, enabling better service visibility. This phase is about building on the foundation, not full automation.

Answer

To achieve full automated AI cloud optimization.

Answer

To maintain basic foundation user tables only.

Answer

To replace the CMDB with external flat files.

Question 12

An enterprise wants to establish clear data ownership and automate the lifecycle management tasks of archiving and retiring old hardware servers. Which native ServiceNow tool should be implemented to govern this process?

Accepted Answer

CMDB Data Manager. CMDB Data Manager is the native application designed to automate lifecycle operations such as backup, retire, delete, and attest for CIs based on policy rules.

Answer

Service Graph Connector

Answer

Discovery Schedule

Answer

Identification and Reconciliation Engine (IRE)

Question 13

When configuring CMDB health metrics, which of the following represents one of the three core pillars measured by the CMDB Health Dashboard?

Accepted Answer

Completeness. The CMDB Health Dashboard in ServiceNow measures three core pillars: Completeness, Compliance, and Correctness. Completeness specifically evaluates whether required CI attributes and relationships are populated, ensuring the CMDB has the necessary data to support IT processes. This is a fundamental metric because incomplete CIs can lead to inaccurate impact analysis and service mapping. The other options—Security, Performance, and Availability—are not part of the CMDB Health Dashboard's core pillars; they are operational metrics tracked elsewhere.

Answer

Security

Answer

Performance

Answer

Availability

Question 14

An IT team wants to create a report that lists all Business Services that depend on a specific database instance, traversing up to three relationship hops away. Which native feature can accomplish this multi-hop relationship extraction?

Accepted Answer

CMDB Query Builder with multi-node relationship steps. CMDB Query Builder is the native tool designed for multi-hop relationship traversal across CMDB classes. It lets you define a starting CI class, add relationship steps (hops) between classes, and filter results — exactly what is needed to find Business Services three hops from a database instance. Standard reports cannot traverse arbitrary relationship depths.

Answer

Standard List Report with parent filter

Answer

CMDB Health Dashboard audit rule

Answer

Service Mapping Traffic Connection report

Question 15

An organization requires a custom report that extracts CIs that match a complex multi-class criteria: Linux servers running a specific Oracle version that connect to a Business Service via a downstream 'Depends on::Used by' relationship. What is the most efficient native way to generate this dataset?

Accepted Answer

Use CMDB Query Builder to construct a multi-node relationship query and save it as a reporting source.. CMDB Query Builder allows administrators to define multi-class, relationship-aware queries across multiple tables and export or report on the resulting dataset.

Answer

Write a Database View joining cmdb_ci, cmdb_rel_ci, and cmdb_software_product.

Answer

Build a custom Service Mapping Traffic Connection report.

Answer

Create a standard ServiceNow List Report on the CI [cmdb_ci] table with multiple join conditions.

Question 16

An implementation specialist is configuring dependency relationships where a virtual machine must be marked as dependent on a physical ESXi host. When utilizing CI relationships, what is the significance of setting the 'Depends :: Used by' relationship direction correctly?

Accepted Answer

It dictates how Business Service Management and Dependency Views calculate impact propagation.. In ServiceNow CMDB, the 'Depends :: Used by' relationship direction defines which CI depends on which, and this direction is what Business Service Management and Dependency Views use to calculate impact propagation. If a VM is set as dependent on an ESXi host, an outage on the host correctly propagates impact to the VM and any services above it. Setting the direction incorrectly reverses the impact tree, causing misleading outage analysis.

Answer

It enforces mandatory database indexing on the cmdb_rel_ci table for both records.

Answer

It determines the physical network routing path used by Discovery.

Answer

It automatically populates the asset tag field on the child CI from the parent CI.

Question 17

During an audit of the cmdb_ci_computer table, you notice that several records lack standard manufacturer and model attributes that are present in the parent cmdb_ci_hardware table. What architectural feature of ServiceNow tables explains why these attributes exist across multiple hardware sub-classes?

Accepted Answer

Table inheritance through dictionary column extension. ServiceNow tables use inheritance: child tables (e.g., cmdb_ci_computer) inherit columns from parent tables (e.g., cmdb_ci_hardware). This means attributes like manufacturer and model are defined once in the parent and automatically available in all child tables, ensuring consistency and reducing redundancy.

Answer

CMDB Data Manager policy enforcement

Answer

Dynamic CI Group membership rules

Answer

Database View joining

Question 18

An administrator needs to ensure that specific critical attributes of a Server CI cannot be overwritten by low-priority discovery sources, while higher-priority integrations can update them. Where is this behavior configured?

Accepted Answer

Reconciliation Definitions. Reconciliation Definitions in ServiceNow specify, per CI class and attribute, which discovery source has precedence and whether lower-priority sources can overwrite values. Configuring a reconciliation definition for the Server class with the critical attributes set to be updated only by higher-priority sources enforces the required behavior.

Answer

Discovery Source Exclusion rules

Answer

CI Class Manager attribute properties

Answer

Access Control Lists (ACLs) on the cmdb_ci table

Question 19

Which THREE of the following are primary components evaluated under the CMDB Health Dashboard framework? (Choose three.)

Accepted Answer

Correctness. The CMDB Health framework evaluates Completeness, Correctness, and Compliance.

Answer

Security

Answer

Performance

Question 20

An IT team is configuring Application Services and wants to understand the difference between a Manual Application Service and a Dynamic CI Group Application Service. Which statement accurately describes their operational differences?

Accepted Answer

Manual services require manual addition of CIs, whereas Dynamic CI Groups use queries to automatically populate CIs.. Manual Application Services require administrators to manually add CIs to the service record, giving precise control but requiring ongoing maintenance. Dynamic CI Group Application Services use a saved query (encoded query) to automatically populate the CIs that match defined criteria, so the service membership stays current as CIs are added or changed. This is the core operational difference between the two types.

Answer

Dynamic CI Groups replace the need for Business Applications entirely.

Answer

Dynamic CI Groups can only be used for hardware CIs, while Manual services are exclusively for software.

Answer

Manual services do not support incident mapping, while Dynamic CI Groups do.
