CIS-DF Practice Test 10 — 10 Questions

Question 1

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?

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

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 2

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 3

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 4

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 5

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.

Question 6

When reviewing CI records ingested into the CMDB, an administrator notices a field labeled 'First discovered' and another labeled 'Last discovered'. Which component populates these lifecycle tracking fields automatically?

Accepted Answer

The Identification and Reconciliation Engine (IRE) and Discovery logging mechanisms. Discovery and the IRE automatically maintain discovery audit metadata, such as first and last discovered timestamps.

Answer

Standard Transform Map execution engine

Answer

CMDB Health Dashboard audit jobs

Answer

Data Policies on the cmdb_ci table

Question 7

Which TWO of the following tasks can be accomplished using the CMDB Data Manager? (Choose two.)

Accepted Answer

Scheduling automated archival of historical CIs. CMDB Data Manager allows administrators to create policies for automating CI lifecycle states such as archival and retirement.

Answer

Visualizing service maps in Service Mapping

Answer

Configuring network IP discovery schedules

Answer

Defining CI identification and reconciliation rules

Question 8

A large enterprise uses CSDM to model its services. The CMDB administrator notices that many Business Applications are not linked to any Application Service, causing a gap in the service hierarchy. The administrator needs to identify these unlinked Business Applications and understand which CSDM domain they belong to. Which CSDM domain should the administrator focus on to resolve this issue?

Accepted Answer

Service Delivery. The CSDM Service Delivery domain encompasses Business Applications, Application Services, and Technical Services, and defines their interrelationships. To find Business Applications not linked to Application Services, the administrator must work within this domain. The other domains serve different purposes: Design and Planning focuses on design, Service Consumption on user-facing offerings, and Foundation on base data.

Answer

Design and Planning

Answer

Service Consumption

Answer

Foundation

Question 9

An architect is troubleshooting relationship cardinality and integrity issues in the CMDB. Which THREE mechanisms or tools help maintain relationship health? (Choose three.)

Accepted Answer

Suggested Relationships configurations. Option B (Suggested Relationships configurations) is correct because Suggested Relationships define the allowed parent-child relationship types between CI classes, enforcing valid cardinality and preventing invalid relationship types from being created in the CMDB. Option C (IRE relationship processing during payload ingestion) is correct because the Identification and Reconciliation Engine applies relationship rules and dependent/containment logic during ingestion, ensuring relationships are correctly matched, deduplicated, and reconciled rather than duplicated or orphaned. Option D (Orphan and Stale audits in CMDB Health Correctness) is correct because these CMDB Health Correctness KPIs detect CIs with missing required relationships (orphans) and outdated relationships (stale), surfacing integrity problems so they can be remediated. Option A is wrong because disabling index generation on cmdb_rel_ci degrades query performance and does not improve relationship health. Option E is wrong because direct SQL updates on cmdb_rel_ci bypass IRE, business rules, and audit logic, risking data corruption and unsupported configurations.

Answer

Disabling the cmdb_rel_ci table index generation

Answer

Manual SQL direct database updates on the cmdb_rel_ci table

Question 10

Which THREE of the following are core goals or benefits of implementing the CSDM framework?

Accepted Answer

Enabling accurate incident and change impact analysis via proper service mapping.. Option C is correct because the CSDM (Common Service Data Model) establishes consistent relationships between services, applications, and infrastructure, which enables accurate impact analysis for incidents and changes through proper service mapping. Option D is correct because CSDM provides a standard, product-agnostic data model that normalizes how configuration items and services are represented in the CMDB, independent of any specific vendor product. Option E is correct because CSDM aligns business applications and business capabilities with the underlying technical infrastructure, creating traceability from business value down to technical components. Option A is incorrect because CSDM is a data modeling framework, not an automation tool for configuring network firewall rules, and it does not bypass administrative approval processes. Option B is incorrect because CSDM strengthens the ServiceNow CMDB as the system of record; it does not replace the database with external spreadsheets, which would contradict its purpose of a unified, governed data model.

Answer

Automatically configuring network router firewall rules without admin approval.

Answer

Replacing the ServiceNow database with external spreadsheets.
