CMDB

The CMDB domain of the CIS-ITSM exam covers ServiceNow Configuration Management Database governance: CI Class Manager, CMDB Health dashboards and KPIs, Identification and Reconciliation Engine (IRE), CI Lifecycle, and attestation. Questions are scenario-based, asking you to pick the correct ServiceNow application, module, or metric to solve a data-quality or audit problem.

What this domain covers

What to know about CMDB

Be able to name the exact ServiceNow application and module for each CMDB task: CI Class Manager for class and lifecycle configuration, CMDB Health for Completeness/Correctness/Compliance scores, and Data Certification for owner attestation. Getting the right application for the scenario is the key skill.

CI Class Manager for class hierarchy, CI lifecycle, and identification/reconciliation configuration

CMDB Health dashboards scoring Completeness, Correctness, and Compliance across CI classes

CMDB Health metrics such as staleness/age measuring CIs not updated or verified recently

Data Certification and attestation for owners verifying physical existence of datacenter CIs

Watch out for

Common CMDB exam traps

  • ▸Confusing CMDB Health with CMDB Compliance or with the IRE; each answers a different question about CI data quality.
  • ▸Assuming CI Class Manager is only for creating classes, missing its role in lifecycle, identification, and reconciliation setup.
  • ▸Mixing up Correctness (data accuracy) with Completeness (required attributes populated) when selecting a health metric.

1

A company wants to automatically retire hardware CIs that have been in an 'In Maintenance' state for more than 180 days without an active update. Which CMDB feature is designed to automate this lifecycle management workflow?

Medium
2

A technician wants to view the graphical relationship hierarchy of a Business Service and its underlying servers. Which feature should they open from a CI record?

Easy
3

Which THREE of the following actions can be performed using CMDB Data Manager? (Choose three.)

Hard
4

Which TWO factors should be considered when defining relationship rules between CI classes? (Choose two.)

Medium
5

A CMDB administrator notices that a large number of Windows servers are being created as duplicate CIs in the CMDB. The servers are discovered by both SCCM and ServiceNow Discovery. After investigation, the administrator finds that SCCM populates the serial_number field with the service tag, while ServiceNow Discovery populates the serial_number field with the BIOS UUID. Both data sources are configured to use the same identification rule that includes serial_number. What is the most likely cause of the duplicates?

Hard
6

While reviewing the CMDB Correctness score, an administrator notices a high count of orphan CIs. What is the definition of an orphan CI in the context of CMDB Health Correctness?

Hard
7

A CMDB administrator is configuring the CMDB Health Dashboard to monitor the health of the CMDB. The administrator needs to ensure that the dashboard includes metrics for the completeness of CI attributes. Which TWO of the following metrics are part of the Completeness pillar in the CMDB Health Dashboard? (Choose two.)

Hard
8

A CMDB administrator needs to ensure that when a CI is retired, it is automatically removed from the CMDB after a specified period to maintain data hygiene. Which feature should the administrator use?

Easy
9

A CMDB administrator needs to ensure that when a discovery source reports a server with the same serial number as an existing CI, the existing CI is updated rather than a duplicate being created. The administrator wants to apply this behavior only to the 'cmdb_ci_linux_server' class and its child classes. Which approach should the administrator take?

Medium
10

A custom integration script is inserting records directly into the cmdb_ci_server table without invoking the Identification and Reconciliation Engine (IRE). What is the primary risk of this approach?

Medium
11

A team wants to create a new relationship type to define a custom dependency between hardware and business applications. Which module should be used to define this new relationship type?

Easy
12

An auditor wants to verify the physical existence and accuracy of datacenter hardware CIs by having owners attest to their records. Which application provides this attestation capability?

Easy
13

An administrator needs to evaluate the overall health of the CMDB, specifically measuring the percentage of CIs that have not been updated or verified within the last 90 days. Which CMDB Health metric addresses this?

Hard
14

An organization notices that manual updates made by technicians to the 'Assigned to' field on server CIs are frequently being overwritten by automated nightly imports. What is the best way to prevent this without disabling the import entirely?

Medium
15

Which TWO of the following are recommended best practices when configuring identification rules in the CMDB? (Choose two.)

Medium
16

Which THREE of the following are benefits of using CI Class Manager? (Choose three.)

Hard
17

An administrator needs to review the overall CMDB health scores for Completeness, Correctness, and Compliance across all classes. Which application and module should they navigate to?

Easy
18

Which THREE of the following statements are true regarding Identification and Reconciliation Engine (IRE) processing? (Choose three.)

Hard
19

A CMDB administrator is configuring the Identification and Reconciliation Engine (IRE) to handle data from multiple discovery sources. The administrator wants to ensure that if two sources provide conflicting values for the same attribute, the source with the highest priority wins. Which IRE feature should be configured to achieve this?

Hard
20

A CMDB administrator is configuring the Identification and Reconciliation Engine (IRE) for a new data source that discovers network switches. The administrator needs to ensure that when a switch is discovered, IRE uses the switch's serial number as the primary identifier and falls back to the MAC address if the serial number is missing. Which configuration should the administrator perform?

Medium
