ServiceNow Certified System Administration Practice

A transform map plays a crucial role in the data import process within ServiceNow by defining how fields from an import set are mapped to corresponding fields in the target table. This mapping is essential because it ensures that the data brought into ServiceNow is correctly aligned with the system's structure and schema. The transform map specifies the source fields, the target fields, and any transformations or conversions that may be necessary during the import process. This functionality allows administrators to accurately manage data, maintain integrity, and ensure that incoming data is appropriately categorized and stored.

While generating transformation reports, collecting data from multiple sources, and optimizing database performance are relevant aspects of data management and system performance, they do not pertain directly to the specific function of a transform map in ServiceNow. The primary focus of a transform map is on the mapping and transformation of data from the import set to the designated target table, making answer B the most accurate representation of its role.
