CIS-DF Practice Test 6 — 10 Questions

Question 1

An administrator is configuring a Robust Transform Engine (RTE) definition for a complex CMDB data import. They need to ensure that if an incoming record fails identification or has missing mandatory attributes, the entire batch does not fail, but instead logs an error for that specific row. Where is this error handling behavior managed in RTE?

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

Accepted Answer

Configure error handling options within the Robust Transform Engine Data Stream Definition and field processors to capture row-level exceptions.. In RTE, error handling is configured within the Data Stream Definition and field processors. This allows row-level error capture, so if a record fails identification or has missing mandatory attributes, the error is logged for that specific row without failing the entire batch.

Answer

Set the Import Set transform map property to 'Ignore Errors' globally.

Answer

Modify the IRE engine configuration property 'glide.cmdb.ire.abort_on_error' to false.

Answer

Write a global Business Rule on sys_import_set_row to catch exceptions.

Question 2

When designing class hierarchy relationships and investigating class behaviors in the CI Class Manager, which THREE options represent capabilities or configurations managed within the CI Class Manager? (Choose three.)

Accepted Answer

Configuring Identification and Reconciliation Engine (IRE) identification rules for the class.. In the CI Class Manager, option A is correct because it is the interface where administrators create and edit Identification and Reconciliation Engine (IRE) identification rules that determine how CIs of a given class are uniquely identified from discovery and import sources. Option B is correct because reconciliation definitions (data source precedence/update priorities) are configured per class in the CI Class Manager to control which source wins when multiple sources update the same CI attribute. Option C is correct because the CI Class Manager provides the class hierarchy explorer where you view, create, and manage class attributes, inheritance, and parent-child relationships. Option D is not correct because custom database views across unrelated tables are built with database tooling or reporting/performance analytics, not the CI Class Manager. Option E is not correct because custom JavaScript for Discovery credential checks is handled through Discovery patterns/sensors and MID Server scripting, not class hierarchy configuration.

Answer

Creating custom database views across unrelated application tables.

Answer

Writing custom JavaScript business logic to execute during Discovery credential checks.

Question 3

Which TWO of the following indicators or statuses can be viewed on a Service Mapping map? (Choose two.)

Accepted Answer

Traffic connections showing active network communication flows between nodes. Option C is correct because Service Mapping maps display traffic-based connections between CIs, showing active network communication flows (such as TCP connections) that were discovered between nodes. Option D is correct because Service Mapping maps can show a partial map status when discovery traversal is incomplete, indicating that some connections or CIs could not be fully mapped. Option A is incorrect because CMDB Data Manager archival policy execution logs are viewed in the CMDB Data Manager, not on a Service Mapping map. Option B is incorrect because individual user session password expiration alerts are not a Service Mapping map indicator. Option E is incorrect because financial asset depreciation schedules and contract end dates belong to asset and contract management, not Service Mapping maps.

Answer

CMDB Data Manager archival policy execution logs

Answer

Individual user session password expiration alerts

Answer

Financial asset depreciation schedules and contract end dates

Question 4

An administrator wants to ensure that all database instance CIs have a populated 'Assigned to' field. Which CMDB Health metric configuration should be updated to track this requirement?

Accepted Answer

Completeness Audit Rules. Completeness Audit Rules in CMDB Health are specifically designed to check whether required fields on CI records are populated. By configuring a completeness rule that targets the 'Assigned to' attribute on the database instance class, the administrator can flag any CI missing that value and track it on the CMDB Health Dashboard. This directly addresses the requirement to ensure the field is filled.

Answer

Compliance Audit Policies

Answer

Correctness Audit Rules

Answer

Identification Rules

Question 5

Your enterprise has multiple regions deploying the same ERP software. You want to map incident and change metrics separately for the North American Production instance versus the European Production instance of the ERP. How should you structure this in the CSDM framework?

Accepted Answer

Create one Business Application record and link two distinct Application Service records to it.. In the CSDM framework, a Business Application represents the logical software product (the ERP), while Application Services represent the specific deployed instances of that application that provide business functionality. To separate metrics for North American Production versus European Production, you need two distinct Application Service records—one per regional instance—both linked to the single Business Application record for the ERP. This structure allows incident and change metrics to be tracked independently at the Application Service level while maintaining a unified view of the Business Application.

Answer

Create two Technical Services and map them directly to the Business Application record.

Answer

Create two separate Business Application records and point them to a single Application Service record.

Answer

Create a single Application Service record and use dynamic tags on incident forms to separate the regions.

Question 6

An administrator is setting up a ServiceNow Discovery schedule for a subnet in a restricted data center. The Discovery schedule runs successfully, but no new CIs are populated in the CMDB. Upon checking the Discovery status, the probes completed, but the horizontal discovery pattern logs indicate a 'Permission Denied' on WMI/SSH commands. Where should the administrator verify the credentials used for this ingestion?

Accepted Answer

In the Credentials table (discovery_credentials) or Credential Aliases, ensuring the correct protocol credentials are mapped to the IP range.. Discovery and ingestion via credentials are managed through Credential Aliases and the Credentials table.

Answer

In CI Class Manager under Discovery Source Precedence.

Answer

In the CMDB Health Dashboard under Audit Rules.

Answer

In the Robust Transform Engine source properties.

Question 7

You need to review the inheritance chain of a specific custom class called cmdb_ci_cloud_firewall. Which ServiceNow module provides a centralized UI to inspect class definitions, attributes, and relationships?

Accepted Answer

Configuration > CI Class Manager. The CI Class Manager (Configuration > CI Class Manager) is the centralized ServiceNow UI for inspecting class definitions, attributes, inheritance chains, identification rules, and relationships. It provides a visual hierarchy view and lets administrators drill into any class, including custom ones like cmdb_ci_cloud_firewall.

Answer

System Definition > Dictionary

Answer

Configuration > Relationships > Matrix

Answer

CMDB Workspace > Health Dashboard

Question 8

A team wants to exclude test and lab servers from being evaluated by strict production CMDB Health completeness rules. What is the best practice method to handle this in ServiceNow?

Accepted Answer

Configure CMDB Health Inclusion Rules. The best practice to exclude test and lab servers from strict production CMDB Health completeness rules is to configure CMDB Health Inclusion Rules. These rules allow administrators to define conditions that determine which CIs are included in health evaluations, so test servers can be filtered out based on attributes like environment or CI class. This avoids modifying global settings or deleting CIs.

Answer

Modify the baseline system properties to ignore completeness globally

Answer

Delete the test server CIs from the CMDB

Answer

Turn off Discovery for the test network

Question 9

An administrator is configuring Data Source Precedence rules in the CMDB. Which TWO of the following statements regarding Data Source Precedence are true? (Choose two.)

Accepted Answer

Administrators can configure Data Source Precedence rules at both the global CMDB level and granularly per CI class.. Option B is correct because Data Source Precedence in the CMDB can be configured at the global level (applying to all CI classes) as well as at the individual CI class level, allowing administrators to tailor precedence granularly where needed. Option D is correct because the core purpose of Data Source Precedence rules is to determine which discovery source (e.g., ServiceNow Discovery, SCCM, manual entry) is authoritative for specific CI attributes when multiple sources attempt to update the same CI, resolving conflicts by source priority. Option A is incorrect because Data Source Precedence applies to data processed through the Identification and Reconciliation Engine (IRE), not just legacy Import Sets without Transform Maps. Option C is incorrect because Data Source Precedence does not perform automatic deletion or aging of CIs; it only governs which source's data wins during updates. Option E is incorrect because Data Source Precedence works alongside Identification Rules within the IRE—it does not replace them, as Identification Rules are still required to determine CI uniqueness and matching.

Answer

Data Source Precedence only applies to data ingested via legacy Import Sets without Transform Maps.

Answer

Data Source Precedence automatically deletes CIs that have not been updated by a high-priority source within 30 days.

Answer

Data Source Precedence rules replace the need for Identification Rules in the IRE.

Question 10

Where in ServiceNow should an administrator navigate to inspect the current list of CMDB classes, review class attribute counts, and check identification rules?

Accepted Answer

Configuration > CI Class Manager. The CI Class Manager (Configuration > CI Class Manager) is the dedicated ServiceNow interface for inspecting and managing CMDB classes, viewing class attributes and their counts, and configuring identification rules per class. It centralizes class hierarchy, attribute metadata, and identification/reconciliation settings in one place.

Answer

System Definition > Tables

Answer

System UI > Forms

Answer

Configuration > CMDB Health Dashboard
