CIS-DF Practice Test 5 — 25 Questions

Question 1

An organization ingests data from two different cloud providers into the CMDB. Provider A populates virtual machines with a serial number, while Provider B populates virtual machines with a BIOS UUID but no serial number. Both providers use the same identification rule which requires serial number. Consequently, Provider B records fail identification and create duplicates. How should the identification rules be configured to correctly handle both providers?

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

Accepted Answer

Configure multiple identification rule entries in CI Class Manager: Entry 1 using serial number, and Entry 2 using BIOS UUID.. To handle multiple identification identifiers across different providers, administrators can configure multiple identification rule entries (e.g., Entry 1 for Serial Number, Entry 2 for BIOS UUID).

Answer

Disable identification rules and rely on legacy transform map coalescing.

Answer

Create a Business Rule to copy the BIOS UUID into the serial number field before ingestion.

Answer

Combine serial number and BIOS UUID into a single compound identification rule entry with an AND operator.

Question 2

Which tab or related list on a Configuration Item form allows a user to manually add a new relationship to another CI without using Discovery?

Accepted Answer

Relationships related list. The Relationships related list on the CI form allows users to view and manually add upstream or downstream relationships.

Answer

Discovery Schedules related list

Answer

CMDB Health related list

Answer

CSDM Alignment related list

Question 3

An organization implements CSDM and wants to ingest business applications and their hosting environments. They receive a payload containing a Business Application CI that references a non-existent Application Service CI. How does the IRE handle references to related CIs that do not yet exist in the CMDB?

Accepted Answer

If the payload includes nested identification blocks for the related CI, the IRE will create the missing CI first and then establish the relationship.. Depending on how the payload is structured (using identification entries or reference payloads), the IRE can either create the referenced CI automatically or fail the relationship creation if criteria are missing.

Answer

References to non-existent CIs are automatically converted into Incident records in IT Service Management.

Answer

The IRE automatically creates dummy placeholder records for any unresolving reference.

Answer

The entire payload is always aborted if any single related reference cannot be resolved immediately.

Question 4

An enterprise architect wants to visualize the hierarchical relationship between Business Applications, Technical Services, and underlying Application Services using native CSDM visualization tools. Which tool provides the most appropriate structured view for this CSDM domain alignment?

Accepted Answer

CSDM Dashboard and CSDM 3.0 widgets. The CSDM conceptual framework and the CSDM steering dashboard or CSDM widgets provide guidance and visualization for mapping relationships across the domains.

Answer

Network Topology Map

Answer

Data Certification schedule view

Answer

Service Portfolio Management workbench hierarchy view

Question 5

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.. Staleness occurs when CIs are not updated by discovery sources within defined timeframes, often caused by decommissioned hardware left unmanaged or inactive discovery schedules.

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 6

An implementer is configuring Service Graph Connectors to ingest infrastructure data into ServiceNow. Service Graph Connectors utilize the Robust Transform Engine (RTE) and the IRE. What is the primary benefit of using Service Graph Connectors over legacy Import Sets for third-party data ingestion?

Accepted Answer

They provide pre-built mapping, utilize the IRE for deduplication, and ensure data aligns with CSDM and CMDB data standards.. Service Graph Connectors adhere to ServiceNow's CSDM and data ingestion standards, leveraging RTE and IRE out-of-the-box to ensure data consistency, deduplication, and proper relationship mapping.

Answer

They allow administrators to bypass CI Class Manager identification rules entirely.

Answer

They completely bypass the database and store CIs in memory for faster reporting.

Answer

They eliminate the need for any network connectivity between the third-party tool and ServiceNow.

Question 7

Which TWO of the following metrics are categorized under the Correctness pillar of the CMDB Health Dashboard? (Choose two.)

Accepted Answer

Duplicate CIs. Correctness metrics on the CMDB Health Dashboard include Duplicate CIs and Orphan CIs.

Answer

CI Staleness (time since last update)

Answer

Service Mapping pattern error count

Answer

Missing mandatory field population

Question 8

An organization is using ServiceNow Discovery to populate servers, but they also have an automated script that injects server maintenance windows into a custom attribute on the server CIs via the IRE. The automated script runs every 15 minutes, whereas Discovery runs nightly. The administrator notices that the maintenance window attribute is frequently wiped out after the nightly Discovery run. What is the most effective way to protect the maintenance window attribute from being overwritten?

Accepted Answer

Configure a Data Source Precedence rule giving the custom script's discovery source a higher priority than 'ServiceNow' for the maintenance window attribute.. Data Source Precedence rules allow prioritizing the custom script's discovery source over ServiceNow Discovery for specific attributes.

Answer

Disable the maintenance window field mapping in the Discovery schedule properties.

Answer

Set the Discovery schedule to run before the custom script.

Answer

Remove the maintenance window attribute from the cmdb_ci table dictionary.

Question 9

When customizing Dependency Views icons and indicators, an administrator wants to display a visual alert symbol directly on a CI node when its associated hardware warranty is expiring within 30 days. How is this achieved within the platform?

Accepted Answer

Configuring CI status indicators or map decorators mapped to a custom script or condition. Dependency Views support indicator icons (decorator badges) which can be configured using UI Macros or indicator mappings associated with CI statuses or alert conditions.

Answer

Enabling Performance Analytics indicator widgets inside the form view

Answer

Creating a business rule on the cmdb_ci table that injects HTML into the map canvas

Answer

Modifying the CMDB Class Manager icon library directly in the sys_ui_icon table

Question 10

An administrator is configuring a Service Graph Connector. They notice that the integration is failing because the inbound payload uses a custom field name for the serial number instead of the standard IRE attribute name `serial_number`. How should this mapping discrepancy be resolved without altering the external source system?

Accepted Answer

Configure an RTE field mapping to translate the custom source field name to the standard `serial_number` attribute expected by the IRE payload.. Robust Transform Engine (RTE) field maps allow renaming or mapping incoming custom source fields to standard target IRE attributes.

Answer

Modify the target CI table dictionary to rename the `serial_number` column to match the external system's custom field name.

Answer

Create a Business Rule on the staging table to drop the custom field.

Answer

Update the CI Class Manager identification rule to use the custom field name.

Question 11

An administrator is troubleshooting an integration that uses Robust Transform Engine (RTE) to ingest software licenses. During testing, records are inserted into staging tables, but the RTE fails to push them into the CMDB via the IRE. Which THREE areas should the administrator inspect to diagnose the failure? (Choose three.)

Accepted Answer

CMDB Integration Results / IRE Execution Logs to identify specific payload rejection reasons.. Troubleshooting RTE-to-IRE integrations requires checking RTE data stream mappings, IRE identification rules, and integration error logs.

Answer

The Service Level Agreement (SLA) definition table for expired response times.

Answer

The UI Macro table for broken form decorators.

Question 12

An administrator is setting up an import using Robust Transform Engine (RTE). They need to ensure that incoming records are only processed if a specific status field equals 'Active'. Where should this conditional filtering be configured within RTE?

Accepted Answer

Configure data stream filters or conditional field processors within the Robust Transform Engine definition.. RTE supports filtering data stream rows using data stream pre-filters or conditional transformers.

Answer

Write an On-Load Client Script on the staging table.

Answer

Modify the identification rule criteria to ignore inactive records.

Answer

Set the Coalesce checkbox on the Transform Map to 'Active'.

Question 13

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.. Identification rules are defined per class and discovery source or governed by the class identification rules, but tuning identification rules or separating payload matching criteria prevents IP address collision.

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 14

A security audit reveals that unauthorized users are modifying critical CI attributes directly on form views. Which ServiceNow platform governance feature can restrict write access to specific CI attributes based on user roles and data classification?

Accepted Answer

Access Control Lists (ACLs) on cmdb_ci fields. Access Control Lists (ACLs) combined with Field-Level Security are used to restrict write access to specific CI fields based on roles.

Answer

Data Certification read restrictions

Answer

Discovery credential filters

Answer

CMDB Data Governance read-only policies

Question 15

A user wants to view the parent-child relationships and upstream/downstream dependencies of a core router in a graphical map format. Which ServiceNow feature should they open?

Accepted Answer

Dependency Views. Dependency Views provide a graphical representation of configuration items and their relationships.

Answer

CI Class Manager

Answer

CMDB Query Builder

Answer

CSDM Dashboard

Question 16

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.. CSDM provides best-practice guidelines for mapping data across ServiceNow products and the CMDB to ensure consistent reporting and workflow execution.

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.

Question 17

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 functionality to deprecate or safely manage class lifecycles, though structural changes must account for existing records.

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 18

When designing a custom class hierarchy in the CMDB, an architect must adhere to best practices to ensure optimal performance and maintainability. Which TWO of the following practices are recommended when creating and configuring custom CI classes? (Choose two.)

Accepted Answer

Extend from an existing appropriate child class (such as cmdb_ci_server) if the new CI shares those attributes.. Best practices dictate extending from the most specific existing parent class and avoiding unnecessary custom tables when an existing class suffices.

Answer

Extend from the cmdb table directly for every new hardware type to ensure clean table isolation.

Answer

Disable inheritance on all custom classes to improve database query execution speed.

Answer

Create a separate custom relationship table for each new custom CI class to maintain relationship integrity.

Question 19

During a CSDM audit, you notice that incidents are being logged directly against Business Applications instead of Application Services. What is the operational impact of this misconfiguration?

Accepted Answer

It prevents targeted impact analysis because Business Applications do not track specific runtime infrastructure or environment details.. Logging incidents directly against Business Applications prevents accurate impact analysis of specific infrastructure outages, as Business Applications lack direct runtime dependencies.

Answer

Users will be unable to view the Business Application in the Service Portal.

Answer

Discovery will fail to update the Business Application record during daily scheduled runs.

Answer

Service Level Agreements (SLAs) will automatically fail to attach to incident records.

Question 20

An architect is reviewing data ingestion methods for the CMDB. Which THREE integration mechanisms natively support or integrate with the Identification and Reconciliation Engine (IRE)? (Choose three.)

Accepted Answer

ServiceNow Discovery. Discovery, ServiceGraph connectors, and RTE/IntegrationHub ETL natively leverage IRE. Standard import sets without RTE and legacy transform maps bypass IRE.

Answer

Manual CSV file import via standard System Import Sets

Answer

Standard Legacy Transform Maps without RTE
