A core principle for data import in ServiceNow is to use authoritative sources. This means:

Trusted Data: Import data from sources that are known to be accurate, reliable, and up-to-date.

Data Integrity: Using authoritative sources ensures the integrity and quality of the data being imported into ServiceNow.

Reduced Errors: Relying on trusted sources minimizes the risk of importing incorrect or inconsistent data.

Why not the other options?

A. Import data first and validate later: This can lead to data quality issues and require significant cleanup efforts.

C. Use ServiceNow as a data proxy: ServiceNow is not designed to be a primary data store for external systems.

D. Schedule imports monthly: The frequency of imports depends on the specific data and its volatility.
