Summary Statistics C. Geometry Validation D. Spatial Join Correct Answer: B Buffer The Buffer tool generates an area (buffer) around selected features to identify areas within a certain distance. Geometry Types: It works with points, lines, and polygons. Types of Buffers: Buffers can be set to a fixed distance, variable distance (based on an attribute), or even multiple rings (using Dissolve Type).

Fixed Distance B. Variable Distance C. Multi-Ring D. Dissolve Correct Answer: B Clip The Clip tool keeps only the areas of features that overlap with the boundary of a specified clip layer. The result is a new dataset that includes only the clipped area. Geometry Types: The Clip tool works with points, lines, and polygons, but the clip layer must be a polygon. Use: The Clip tool is often used to focus analysis on specific areas, such as clipping vegetation data to the boundaries of a park. What is the primary function of the Clip tool in ArcGIS? A.
