An architect wants to load an XML file created through the Excel Metadata Builder. Where in the application would the architect load this XML file?

The correct option indicates that an architect should load an XML file created through the Excel Metadata Builder from the Application Tab under Tools and then select Load/Extract. This pathway is specifically designed for handling configuration and metadata-related functionalities, including the import of structures defined in XML format.

When dealing with XML files that contain metadata, the Application Tab provides the necessary tools that focus on application-specific settings and configurations, which is particularly relevant for loading metadata that defines elements such as cubes, dimensions, and attributes for the OneStream application. This functionality allows the architect to ensure that the loaded metadata integrates properly within the existing application framework, maintaining data integrity and structure.

The other options, while sounding plausible, would not provide the correct navigation for loading an XML metadata file. For instance, the System Tab typically focuses on broader system administration tasks rather than application-specific metadata loading. The Tools option within the Spreadsheet allows for different functionalities that do not pertain to XML metadata imports.
