Esri ArcGIS Pro Foundation Certification Practice Test

What type of data does a vector layer in ArcGIS Pro typically represent?

1. Continuous data

2. Discreet data

3. Raster data

4. 3D data

The correct answer is: Discreet data

Vector layers in ArcGIS Pro typically represent discrete data. Discrete data refers to quantifiable measurements that can be counted and usually represent distinct entities or features, such as points, lines, and polygons. These features can represent real-world objects like cities, roads, and boundaries that have specific locations and shapes. For instance, a point would represent a specific location like a park or a landmark, a line could represent a river or a road, and a polygon might represent an area such as a state or a land parcel. Each feature has unique attributes associated with it, making vector data highly useful for applications like analysis, mapping, and geographic information systems (GIS). In contrast, continuous data, which is not typical of vector layers, reflects phenomena that exist across a continuum, such as temperature or elevation. Raster data refers to pixel-based information where each pixel corresponds to a value, commonly used for continuous data types. Finally, while 3D data can be represented using vectors, it doesn't specifically denote the primary use of vector layers, which is to represent discrete entities. Thus, discrete data is the most appropriate choice for what vector layers represent in ArcGIS Pro.
