CIS-ITSM CMDB — 10 Questions

Question 1

An administrator creates a custom identification rule for a new class. The rule has two entries: Entry 1 uses 'serial_number' (weight 100), and Entry 2 uses 'mac_address' (weight 50). When a payload arrives containing both attributes, how does the IRE evaluate the rule entries?

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

Accepted Answer

The IRE evaluates Entry 1 first. If a match is found, it uses that CI; if no match is found, it proceeds to evaluate Entry 2.. IRE evaluates identification rule entries in order of their priority or weight, or matches using the first matching entry based on configuration criteria.

Answer

The IRE averages the weights and creates a new CI if the combined score is below 75.

Answer

The IRE rejects the payload because conflicting matching criteria are defined within the same rule.

Question 2

A business service map displays a critical application server as disconnected from its underlying database. Upon investigation, the database CI was updated with a new IP address, breaking the relationship. Which ServiceNow feature helps automatically maintain relationships when attributes change?

Accepted Answer

Identification and Reconciliation Engine relationship processing via Discovery patterns. Service Mapping and Discovery rely on IRE and pattern synchronization, but relationship maintenance is often preserved through automated discovery or reference qualifier linkage. When considering CMDB core mechanisms, IRE handles updates, and relationship rules or dynamic CI groups maintain groupings.

Answer

Dependency View Auto-Heal Business Rule

Answer

Dynamic CI Group query rules

Answer

CMDB Data Manager relationship synchronizer

Question 3

Which TWO of the following are core components evaluated by the CMDB Health Dashboard? (Choose two.)

Accepted Answer

Completeness. CMDB Health consists of three pillars: Completeness, Correctness, and Compliance.

Answer

Security

Answer

Availability

Answer

Performance

Question 4

Which TWO of the following tables are standard base or parent tables in the CMDB hierarchy? (Choose two.)

Accepted Answer

cmdb_rel_ci. cmdb and cmdb_ci are foundational parent tables for all configuration items and related metadata in ServiceNow.

Answer

sys_user

Answer

incident

Answer

ast_contract

Question 5

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?

Accepted Answer

Staleness (Compliance metric). CMDB Health consists of Completeness, Correctness, and Compliance. Compliance measures metrics such as audits and freshness/staleness based on last update times.

Answer

Orphans (Correctness metric)

Answer

Audit (Completeness metric)

Answer

Duplicate CIs (Correctness metric)

Question 6

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?

Accepted Answer

Dependency View. Dependency Views provide a graphical map of CIs and their relationships, allowing technicians to inspect upstream and downstream impacts.

Answer

Relationship Builder

Answer

CMDB Dashboard

Answer

CI Class Manager

Question 7

An organization requires that network gear attributes can only be updated by the Network Discovery data source, while server attributes can be updated by both Discovery and a manual import set. Where must this restriction be configured?

Accepted Answer

Reconciliation Definitions. Reconciliation definitions in the IRE determine which data sources are authorized to write to specific CI attributes, preventing lower-priority sources from overwriting authoritative data.

Answer

Access Control Lists (ACLs)

Answer

CI Class Manager Identification Rules

Answer

Data Source Precedence Rules

Question 8

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?

Accepted Answer

It bypasses identification rules and reconciliation rules, risking data duplication and unauthorized overwrites.. Bypassing the IRE means duplicate CIs can be created, and reconciliation rules governing attribute updates will not be enforced, compromising data integrity.

Answer

It causes ServiceNow to automatically reject all incoming records due to missing UI policies.

Answer

It prevents the CIs from ever being viewed in the Dependency View.

Answer

It triggers an infinite loop in the Discovery pattern engine.

Question 9

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?

Accepted Answer

Relationship Types. Relationship Types (cmdb_rel_type) define the directional relationship labels between CIs and can be created or modified via the Relationship Types module.

Answer

Dependency View Configurator

Answer

CI Relationship Rules

Answer

CMDB Groups

Question 10

An administrator needs to ensure that network gear discovered by Discovery is classified under a specific custom child table of cmdb_ci_netgear. Where should the administrator define the classification criteria to map network devices to this custom table?

Accepted Answer

CI Class Manager. CI Class Manager is the centralized location used to manage CI classes, including setting up identification rules, reconciliation rules, and classification criteria for discovered items.

Answer

Discovery Definition > Network Classifications

Answer

CMDB Properties

Answer

CI Identifier Rules module
