Which statement is true about reading data from a URL using a reader's Dataset parameter?

• A. It is not supported.
• B. It only reads local files.
• C. It requires an HTTP proxy.
• D. It is supported.

Answer: (D)

Reading data from a URL through a reader's Dataset parameter is supported. The Dataset field can accept not only local file paths but also web addresses (http/https) to remote datasets, allowing you to fetch and read data directly from the web. This capability means you can integrate online data sources into your workflow without first downloading files to disk. While some readers or network environments might require authentication or proxy settings, those are environment-specific needs—not a limitation of the feature itself. The other statements imply restrictions that don’t apply universally, whereas the actual capability is that reading from a URL is supported.
