Which parameter is used to read downloaded datasets via a Connector into a FeatureReader?

• A. The URL parameter
• B. The _dataset parameter
• C. The FileName parameter
• D. The Schema parameter

Answer: (B)

The parameter used to read a downloaded dataset inside a Connector into a FeatureReader is the _dataset parameter. This lets the reader know which specific dataset within the downloaded bundle (such as a ZIP or archive containing multiple files) to open and stream as features. The URL parameter is for where to download from, not which item to read once downloaded. The FileName parameter would point to a single file, but the reader needs to know which dataset inside the downloaded content to use. The Schema parameter deals with the data structure, not dataset selection.
