CIS-DF Configuration Practice Test 2 — 15 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.. Inheritance allows the new class to automatically leverage existing attributes, identification rules, and relationship definitions associated with the parent class.

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

Which ServiceNow table is designated as the universal base table from which all Configuration Item classes ultimately inherit?

Accepted Answer

cmdb. The cmdb table is the root table for all configuration items in ServiceNow.

Answer

cmdb_ci

Answer

cmdb_rel_ci

Answer

task

Question 3

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 health rules are used to audit whether mandatory or recommended fields (such as 'Assigned to') are populated on CIs.

Answer

Compliance Audit Policies

Answer

Correctness Audit Rules

Answer

Identification Rules

Question 4

An administrator is configuring a Robust Transform Engine (RTE) integration to populate the CMDB from a third-party asset management system. Why is RTE recommended over a standard Transform Map for CMDB data loads?

Accepted Answer

RTE processes data through the Identification and Reconciliation Engine (IRE), preventing duplicates and enforcing data integrity.. Robust Transform Engine integrates natively with the Identification and Reconciliation Engine (IRE), ensuring data is properly reconciled and duplicate CIs are prevented.

Answer

RTE automatically translates foreign languages in source data payloads.

Answer

RTE eliminates the need for staging tables during data imports.

Answer

RTE bypasses all access control lists to accelerate import times.

Question 5

Your organization has deployed multiple datacenters, and engineers want to restrict visibility of specific server CIs so that regional support teams only see their local hardware. Which mechanism should be used to achieve class-level or record-level data segregation in the CMDB?

Accepted Answer

Access Control Lists (ACLs) combined with location or company attributes. Domain Separation or Contextual Security (Security Rules / ACLs) can restrict access to CMDB records based on attributes like location or company.

Answer

CI Class Manager hiding classes from navigation

Answer

Modifying Discovery Schedule target IP ranges

Answer

Disabling Dependency Views for non-admin users

Question 6

When reviewing relationship data in your CMDB, you notice a large number of 'Orphan' CIs reported on the CMDB Health Dashboard. What does an orphan CI represent?

Accepted Answer

A CI that has no parent or child relationships defined in the cmdb_rel_ci table.. An orphan CI is a configuration item that lacks any relationship links to other CIs in the CMDB.

Answer

A CI whose primary discovery source has been deleted.

Answer

A CI assigned to an inactive user group.

Answer

A CI that has not been scanned by Discovery in over 60 days.

Question 7

An administrator needs to create a new relationship type between databases and storage volumes that does not exist out-of-the-box. Which table should be updated to define this new relationship type?

Accepted Answer

cmdb_rel_type. New relationship definitions are added to the Configuration Item Relationship Types table (cmdb_rel_type).

Answer

cmdb_ci_rel_server

Answer

cmdb_rel_ci

Answer

sys_choice

Question 8

When analyzing CMDB data quality, you discover multiple records representing the exact same physical server, but they were created by different discovery tools with slightly different naming conventions. The IRE successfully merges them during updates, but initial creation still generates duplicates. What is the root cause?

Accepted Answer

Reconciliation definitions are set to allow multiple sources.. If identification rules are misconfigured or criteria are missing, the IRE cannot match incoming payloads during initial insertion, leading to duplicate creation.

Answer

The cmdb_rel_ci table is missing indexes.

Answer

The CMDB Health Dashboard needs to be restarted.

Question 9

A company has implemented strict data governance where CIs that have not been discovered or updated in over 90 days are considered stale. Where should this threshold be configured in ServiceNow?

Accepted Answer

CMDB Health Dashboard Correctness settings. Stale CI thresholds are configured within the Correctness settings of the CMDB Dashboard / CI Class Manager audit rules.

Answer

CI Class Manager relationship rule definitions

Answer

Discovery Schedule properties

Answer

Data Archiving rule definitions

Question 10

Which TWO of the following actions can be performed directly within the CI Class Manager? (Choose two.)

Accepted Answer

Create and modify identification rules for a CI class. CI Class Manager allows administrators to view and configure identification rules and class attributes. It does not run discovery schedules or build complex multi-table analytics queries.

Answer

Configure Service Level Agreements (SLAs) for incident resolution

Answer

Schedule and execute Discovery network scans

Answer

Build graphical multi-table CMDB queries

Question 11

When configuring the Identification and Reconciliation Engine (IRE) for a complex multi-source data environment, which THREE components or concepts are critical to understand and configure properly? (Choose three.)

Accepted Answer

Identification Rules. IRE relies on Identification Rules for matching, Reconciliation Definitions for precedence, and Payload structure for processing. Dependency views and Transform maps are separate components.

Answer

Standard Legacy Transform Maps without RTE

Answer

Dependency View graphical layout settings

Question 12

Which TWO metrics are part of the Correctness pillar in the CMDB Health Dashboard? (Choose two.)

Accepted Answer

Orphans. Correctness tracks data integrity issues such as duplicate CIs, stale CIs, and orphan CIs. Required field population is tracked under Completeness.

Answer

Software license audit compliance

Answer

Required fields populated

Answer

Recommended attributes filled

Question 13

When designing class hierarchy extensions in the CMDB, which THREE best practices should an implementation specialist follow? (Choose three.)

Accepted Answer

Avoid excessively deep class hierarchies unless justified by distinct identification or attribute requirements.. Best practices include subclassing from appropriate existing parents, avoiding unnecessary deep hierarchies, and reusing existing attributes before creating custom ones.

Answer

Bypass the CI Class Manager and create database tables directly in System Definition.

Answer

Create a brand new base table directly under cmdb for every new hardware vendor.

Question 14

Which TWO statements are true regarding Configuration Item (CI) relationships in ServiceNow? (Choose two.)

Accepted Answer

Relationships are directional, typically defined between a parent CI and a child CI.. Relationships are stored in cmdb_rel_ci and can be directional (parent/child). They are not limited to 1:1 and are distinct from reference fields.

Answer

Creating a relationship automatically deletes both CIs if one is updated.

Answer

A CI can only participate in a single relationship across the entire CMDB.

Answer

Relationships and reference fields (like 'Assigned to') function in the exact same manner.

Question 15

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
