Final answer:
ServiceNow can import data from JDBC, LDAP, and REST (Integration Hub) when a valid transform map is available, which are commonly used data source types for data integration in ServiceNow.
Step-by-step explanation:
ServiceNow can import data from several external data sources when a valid transform map is available. The types of external data sources from which ServiceNow can import data include:
- JDBC - Java Database Connectivity allows connection to a wide variety of databases.
- LDAP - Lightweight Directory Access Protocol is used for reading from and writing to directories over an IP network.
- REST (Integration Hub) - Representational State Transfer allows interacting with web services using the HTTP protocol.
While OIDC (OpenID Connect) is related to authentication rather than data import, and Custom (Load by Script) is a method to execute scripts to import data, these options are not standard out-of-the-box solutions for importing into ServiceNow via a transform map.
