Multiple object source types can be used with which of the following? (Select two)

The selection of Salesforce objects is correct because Salesforce supports a multi-object API that allows users to work with multiple related objects simultaneously within a single operation. This is especially beneficial when you want to extract or manipulate data that spans different related entities in Salesforce, all of which can contain relevant data for the task.

While other source types like flat files, database tables, and NoSQL databases may allow for some level of multitasking, they generally do not provide the structured, relational capabilities provided by Salesforce. Specifically, each of those options typically refers to single sources of data rather than a cohesive set of interrelated objects that can be accessed together in the way Salesforce does. For instance, flat files are generally one-dimensional, database tables may represent singular relationships, and NoSQL databases often emphasize flexibility over strict relationships. Hence, Salesforce stands out as a source type that inherently supports multiple related object interactions.
