Which type of shape is not possible to create with the geometry published parameter?

• A. Point
• B. Line
• C. Cube
• D. Polygon

Answer: (C)

The concept being tested is what geometry types a geometry published parameter can carry. In FME, a geometry published parameter is designed to hold 2D geometries—points, lines (or polylines), and polygons. These are flat shapes defined in a plane. A cube, however, is a 3D solid with volume, which cannot be represented as a single 2D geometry in that parameter. To represent a cube, you’d need 3D geometry capabilities within the workspace (for example, constructing a 3D model from multiple elements or using 3D transformers), not a single 2D geometry passed through a published parameter. Thus, the cube is not possible, while a point, line, or polygon is.
