CIS-DF Ingest Practice Test 4 — 15 Questions

Question 1

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.)

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

Accepted Answer

Precedence rules can be configured to allow specific data sources to update designated attributes while blocking others.. Precedence rules operate hierarchically, can be customized per class, and rely on exact discovery source string matching.

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 2

An organization is troubleshooting duplicate CIs appearing in the CMDB after running a new integration. Which TWO administrative actions should be taken to investigate and resolve this issue? (Choose two.)

Accepted Answer

Inspect CI Class Manager identification rules for the affected class to ensure unique attributes are correctly defined.. Investigating duplicates involves inspecting identification rules and checking IRE payload logs for matching failures.

Answer

Modify Access Control Lists to hide duplicate CIs from users.

Answer

Increase the timeout limit on all REST Message records.

Answer

Delete all Discovery schedules and recreate them from scratch.

Question 3

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 4

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 5

Which ServiceNow module provides a centralized dashboard view of CMDB data quality metrics, including completeness, correctness, and compliance?

Accepted Answer

CMDB Health Dashboard. The CMDB Health Dashboard provides health calculations across completeness, correctness, and compliance.

Answer

Transform Map Metrics

Answer

Discovery Status Dashboard

Answer

Service Mapping Workbench

Question 6

An administrator is configuring an IntegrationHub Spoke to ingest data from an external monitoring tool into the CMDB. The integration uses the IRE to process payloads. When testing the action, the payload returns an error stating that the payload is missing the mandatory 'className' property. How should the administrator correct this?

Accepted Answer

Ensure the JSON payload structure includes the `className` parameter for each CI object, specifying the exact target table name (e.g., `cmdb_ci_linux_server`).. IRE payloads require a valid `className` property for each CI object to identify which CMDB table the record belongs to.

Answer

Add a Transform Map to the IntegrationHub action.

Answer

Modify the table name in the Data Source record.

Answer

Configure a Data Policy on the REST Message form.

Question 7

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?

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 8

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 9

Which role is typically required to configure Identification Rules and Data Source Precedence rules in the CI Class Manager?

Accepted Answer

cmdb_admin or admin. Admin or cmdb_admin role is required to modify CMDB class definitions and identification rules.

Answer

discovery_admin only

Answer

asset

Answer

itil

Question 10

An enterprise has implemented strict identification rules requiring serial numbers for all hardware. However, a batch of legacy network hubs has no serial numbers encoded in firmware. When ingested via import sets, the IRE rejects every record due to missing identification attributes. The business wants these records ingested into the CMDB anyway, using their MAC address as the unique identifier. What is the correct way to accommodate this?

Accepted Answer

Add a second identification rule entry for the hardware class in CI Class Manager where the identification criteria uses MAC address.. Adding a secondary identification rule entry using MAC address allows devices without serial numbers to be correctly identified and ingested.

Answer

Change the target table to cmdb_ci_appl.

Answer

Disable the identification rule entirely for the hardware class.

Answer

Write a Business Rule to insert fake serial numbers starting with 'UNKNOWN' into every record.

Question 11

An administrator is troubleshooting an integration where an incoming JSON payload contains relationships between servers and IP addresses. The server is created successfully, but the relationship record in `cmdb_rel_ci` is missing. Upon checking the IRE execution log, the system indicates that the relationship type string was invalid. How should this be resolved?

Accepted Answer

Ensure the relationship type specified in the payload matches an active parent/child relationship name defined in the `cmdb_rel_type` table.. Relationship types specified in payloads must match active record values in the `cmdb_rel_type` table.

Answer

Disable relationship validation in CMDB properties.

Answer

Create a Transform Map to map relationship types.

Answer

Modify the cmdb_rel_ci table dictionary to allow free-text relationship types.

Question 12

When configuring a Service Graph Connector, where does an administrator typically test and execute the data ingestion process to verify that source data maps correctly to staging tables and the CMDB?

Accepted Answer

Data Sources module -> Select the Data Source -> Click 'Test Load 20 Records' or 'Execute Now'. Service Graph Connectors use Data Sources and Scheduled Data Imports, which can be tested via the 'Execute Now' feature.

Answer

Discovery Status -> Run Quick Discovery

Answer

Service Mapping Workbench -> Test Map

Answer

CI Class Manager -> Test Ingestion

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

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 15

An enterprise is designing a multi-source data ingestion architecture for their CMDB, combining Discovery, Service Graph Connectors, and manual spreadsheet imports. Which THREE governance practices should be implemented to ensure data integrity? (Choose three.)

Accepted Answer

Ensure robust identification rules are configured in CI Class Manager to prevent duplicate CI creation.. Multi-source CMDB ingestion governance requires unique identification rules, distinct discovery sources, and clear precedence rules.

Answer

Allow all data sources to use the default 'Discovery' source string to simplify configuration.

Answer

Bypass the IRE for manual spreadsheet imports to allow unrestricted table updates.
