ServiceNow Certified System Administration Practice

A row in ServiceNow is defined as a single record in a table. In the context of ServiceNow, tables are structured collections of data, and each entry or record within these tables corresponds to a row. Each row contains information related to the specific instance of the data being tracked, whether that be a user, incident, change request, or any other entity represented in the platform.

The other possibilities refer to different aspects of data management. While a unique identifier is crucial for differentiating between rows, it does not encompass all the data included in a row. Similarly, an instance of a data type refers to a specific entry of a data type but doesn't define what a row is as a whole. A collection of fields pertains more to the structure of the table itself rather than a single unit of data, which is what a row represents. Thus, the correct definition of a row is indeed that it is a single record in a table.
