Question 9

A company discovers that multiple discovery sources are overwriting authoritative manual updates to server asset tags. Which governance mechanism should be configured to protect specific attributes from being updated by automated discovery?

Accepted Answer

Reconciliation Definition (Data Precedence). Reconciliation definitions allow administrators to specify data precedence rules, protecting manually curated attributes from automated discovery overwrites.

Answer

Discovery Schedule Exclude filters

Answer

Access Control Lists (ACLs)

Answer

Business Rules on the cmdb_ci table

Question 10

Which THREE actions occur when a Data Certification task is assigned to a CI owner? (Choose three.)

Answer

The CI is automatically retired from the database immediately

Answer

A high-priority incident is automatically created for the IT service desk

Question 11

An administrator needs to create a new custom Configuration Item class to track specialized network routers. Where should this class be created within the ServiceNow platform?

Accepted Answer

Configuration > CI Class Manager. Custom CI classes must be created using the CI Class Manager, which provides a structured interface for defining new child classes and managing their hierarchy under the appropriate base class.

Answer

System Definition > Tables

Answer

System Dictionary > New Class

Answer

Configuration > CMDB Properties

Question 12

During which CSDM maturity phase does an organization typically implement Service Portfolio Management and basic Business Service mapping?

Accepted Answer

Walk. Walk is the second CSDM phase, where organizations introduce service portfolios and map basic services.

Answer

Run

Answer

Fly
