CIS-DF Practice Test 7 — 10 Questions

Question 1

When designing a custom CI class hierarchy, what is the primary benefit of inheriting from an existing parent class rather than creating an entirely independent base table?

Accepted Answer

It automatically inherits parent class attributes, identification rules, and relationship definitions.. Inheriting from an existing parent class in the CI class hierarchy allows the child class to automatically inherit attributes, identification rules, and relationship definitions from the parent. This promotes consistency, reduces configuration effort, and ensures that the child class adheres to the same data model and identification logic as the parent.

Answer

It bypasses the need for IRE processing.

Answer

It prevents the table from ever being deleted.

Answer

It automatically populates data from external discovery sources without mapping.

Question 2

A company discovers that multiple discovery sources are overwriting authoritative manual updates to server asset tags. Which governance mechanism should be configured to protect specific attributes from being updated by automated discovery?

Accepted Answer

Reconciliation Definition (Data Precedence). Reconciliation Definitions (Data Precedence) in the CMDB control which data source wins when multiple sources update the same CI attribute. By configuring a reconciliation rule that gives manual/authoritative sources higher precedence than discovery sources for specific attributes, you protect manual updates from being overwritten by automated discovery.

Answer

Discovery Schedule Exclude filters

Answer

Access Control Lists (ACLs)

Answer

Business Rules on the cmdb_ci table

Question 3

What is the primary objective of the 'Crawl' phase in the CSDM framework?

Accepted Answer

To establish foundational data and baseline CMDB population.. The Crawl phase in the CSDM framework is the initial stage where organizations establish foundational data and baseline CMDB population. It focuses on getting the core configuration management data into the CMDB accurately, setting the stage for later phases like Walk and Run. This phase is about creating a solid data foundation, not about retiring applications or achieving full financial optimization.

Answer

To retire all legacy applications across the enterprise.

Answer

To publish all service catalog offerings to external customers.

Answer

To achieve full enterprise financial cost allocation and automated AI optimization.

Question 4

Which TWO methods can be used to assign data ownership to configuration items in the CMDB to support governance and accountability? (Choose two.)

Accepted Answer

Populating the 'Owned by' or 'Managed by' fields on the CI record. Option C is correct because the 'Owned by' and 'Managed by' fields on a CI record are the standard ServiceNow reference fields used to designate the person or group accountable for a configuration item, directly supporting governance and accountability. Option E is correct because CMDB Data Manager policies let you define CI filter criteria and then automatically assign ownership fields (such as 'Owned by' or 'Managed by') in bulk, which is the scalable, policy-driven way to enforce ownership across the CMDB. Option A is not correct because ACL rules on cmdb_ci control read/write access to records, not the assignment of ownership data. Option B is not correct because Discovery behavior patterns are used to identify and classify CIs and their attributes during discovery, not to inject firewall rules or set ownership. Option D is not correct because adjusting Discovery schedule probe frequency only changes how often discovery runs and has no bearing on assigning CI ownership.

Answer

Editing ACL rules on the cmdb_ci table

Answer

Modifying Discovery behavior patterns to inject custom firewall rules

Answer

Adjusting Discovery schedule probe frequency

Question 5

An organization is setting up its CSDM framework and has defined several Business Capabilities. How do Business Capabilities relate to Business Applications in the Design domain?

Accepted Answer

Business Applications realize Business Capabilities.. In the CSDM Design domain, Business Applications are the technological realization of Business Capabilities — meaning each application exists to enable one or more capabilities. This is a many-to-many relationship modeled via the capability reference on the Business Application record. The Design domain intentionally separates the 'what' (capability) from the 'how' (application) so that capability maps remain stable even as applications change.

Answer

Business Capabilities are mapped directly to Hardware CIs.

Answer

Business Capabilities are children of Application Services.

Answer

Business Capabilities replace the need for Business Applications entirely.

Question 6

An organization is configuring ITSM processes to use CSDM data. When a user submits an incident, which CI field on the incident form should be populated to ensure proper service alignment according to CSDM?

Accepted Answer

Configuration Item [cmdb_ci] referencing an Application Service.. According to CSDM, when a user submits an incident, the Configuration Item [cmdb_ci] field on the incident form should be populated with a reference to an Application Service. This ensures that the incident is aligned with the service that is affected, enabling proper impact analysis and routing. The Application Service is a key CSDM entity that represents a service provided by applications, and it is the appropriate CI to link to incidents for service alignment.

Answer

Service Portfolio [service_portfolio] directly.

Answer

Business Application [cmdb_ci_business_app] directly.

Answer

Foundation Company [core_company] directly.

Question 7

An administrator is reviewing the CMDB Health Dashboard and notices high staleness scores across several server classes. Which TWO of the following data ingestion practices contribute to high CMDB staleness? (Choose two.)

Accepted Answer

Failing to run Discovery or integration updates regularly against active infrastructure.. Option D is correct because CMDB staleness measures how long CIs have gone without being refreshed by a trusted data source; if Discovery or integration jobs are not scheduled and run regularly against active infrastructure, the last-discovered timestamps age beyond the staleness thresholds defined in CMDB Health, driving up staleness scores. Option E is correct because decommissioned CIs that are never updated to a non-operational status or retired, and CIs whose source integrations have stopped feeding data, retain old last-updated values indefinitely, which the CMDB Health staleness metric flags as stale. Options A, B, and C do not contribute to staleness: the Identification and Reconciliation Engine (IRE) is the recommended mechanism for automated imports and actually improves data quality, certified Service Graph Connectors are the supported, continuously maintained ingestion path, and Data Source Precedence rules govern which source wins for an attribute rather than how frequently CIs are refreshed.

Answer

Using the Identification and Reconciliation Engine for all automated imports.

Answer

Ingesting data exclusively through certified Service Graph Connectors.

Answer

Configuring robust Data Source Precedence rules for all attributes.

Question 8

An organization uses Service Mapping to map a critical e-commerce application. During mapping, a custom web server process is discovered on a host, but it fails to establish a relationship with the underlying software installation. Where should the administrator verify or configure the identification rules for process classification and mapping?

Accepted Answer

In Service Mapping Configuration, review and adjust Process Classifiers and Application Patterns.. Process classification and identification for Service Mapping are configured via Application Patterns and Process Classifiers within Service Mapping configuration.

Answer

In Robust Transform Engine (RTE) definitions, map the process table to the software installation table.

Answer

In CI Class Manager, modify the Identification Rule for cmdb_ci_appl.

Answer

In Data Source Precedence rules, set Discovery as the primary source for process tables.

Question 9

An organization is migrating from a legacy configuration management database to ServiceNow. They load initial server records using custom import sets without the IRE. Later, they enable ServiceNow Discovery. They notice that every discovered server creates a duplicate CI right alongside the imported record. What caused this duplicate creation?

Accepted Answer

The legacy import bypassed the IRE, failing to populate the sys_object_source tracking table with the correct native keys and discovery source identifiers.. Records ingested without the IRE lack the proper sys_object_source tracking and native identifier linkage expected by Discovery and the IRE, resulting in failure to recognize existing records.

Answer

Discovery is hardcoded to ignore any records created by Transform Maps.

Answer

The cmdb_ci table has a business rule that forces duplicate insertion for security purposes.

Answer

Data Source Precedence rules were not set to 'Manual' before running Discovery.

Question 10

A company deploys a multi-tenant cloud environment. They need to ensure that CIs belonging to Tenant A are logically segregated and cannot be viewed or modified by users belonging to Tenant B, while utilizing a single shared CMDB. Which ServiceNow feature should be configured?

Accepted Answer

Domain Separation. Domain Separation is the ServiceNow feature designed to logically segregate data, processes, and users across multiple tenants within a single instance. By assigning CIs and users to domains, you ensure that Tenant A's users cannot see or modify Tenant B's CIs, even though both reside in the same CMDB tables. This is the only option that provides true multi-tenant isolation at the data level.

Answer

Data Policies enforced on the cmdb_ci table

Answer

Row-level Security via standard ACLs only

Answer

CMDB Baseline auditing
