To visualize population change, the attribute (change in population) must be accessible to the county feature layer’s symbology engine. A Join operation adds the table fields directly to the feature layer’s attribute table based on a common key (county field), making the data available for symbology classification.

Relate creates a temporary relationship but does not merge data for symbology purposes.

Spatial Join is used when spatial relationships are needed; here, the relationship is attribute-based.

Join correctly allows the standalone table values to drive symbology on the spatial features.

Therefore, the correct answer is B.

The extremely large and small values (3.48e+38 and 3.48e-38) indicate that valid statistics (min and max values) have not been calculated for the mosaic dataset. Without statistics, ArcGIS assigns default extreme placeholder values. Running the “Build Statistics” tool will calculate the correct min and max elevation values.

Color balance (Option A) affects display but not data statistics.

Overviews (Option C) improve display performance but do not affect statistics calculation.

Therefore, the correct answer is B.

—

The black-and-white checkerboard indicates that the mosaic dataset cannot locate the source rasters. Repair Mosaic Dataset Paths allows the analyst to correct the file paths if the rasters have been moved or renamed, thus restoring visibility.

Define Overviews (Option A) creates reduced-resolution overviews for fast display but does not fix broken paths.

Build Pyramids (Option B) builds pyramids for raster display performance but also requires valid data paths first.

Therefore, the correct answer is C.

ArcGIS Pro allows filtering of layers in the Contents pane using various filters. The most efficient way to check which layers have definition queries applied is to use the filter option “Active Definition Query” directly in the Contents pane. This instantly shows only those layers that have active definition queries, allowing rapid verification across multiple layers without needing to click through each layer’s properties individually.

Option A requires selecting each layer one-by-one.

Option C also requires manual inspection of each layer’s properties.

Option B provides a batch view directly within the Contents pane.

Therefore, the correct answer is B.

—

Visibility range (also called scale range) controls at what zoom levels a layer or features are displayed. This allows the map to automatically hide features when zoomed out too far, improving performance and reducing clutter, while showing detailed features as the user zooms in.

Definition query (Option A) filters features based on attribute values, not map scale.

Display filters (Option C) filter features at specific scales but require advanced configuration; visibility range is more direct for simple scale-based drawing control.

Therefore, the correct answer is B.

—

ArcGIS Pro can read and display MrSID format rasters but cannot write or export data into MrSID format because it is a proprietary format that requires special licensing for encoding.

IMAGINE Image (Option A) is fully supported for both reading and writing.

GIF (Option B) can be written for exporting simple images but is not ideal for full raster datasets.

MrSID (Option C) is read-only by default in ArcGIS Pro.

Therefore, the correct answer is C.

—

The Range property allows dynamic filtering of features based on numeric attributes such as floor number. By setting the floor number as the range field, users can interactively slide through floors in a 3D scene.

Time (Option A) filters features based on temporal data.

Elevation (Option C) controls the vertical placement of features but does not allow interactive filtering by floor.

Therefore, the correct answer is B.

—

Calculation rules automatically calculate attribute values based on spatial relationships, other attribute values, or predefined logic at the time of feature creation or update. In this scenario, the intersecting building name can be assigned automatically to the site feature using a calculation rule.

Validation rules (Option A) check for rule compliance but don’t assign values.

Constraint rules (Option B) prevent invalid edits but do not calculate fields.

Therefore, the correct answer is C.

—

The Data Engineering view in ArcGIS Pro provides quick access to key statistics (total, mean, min, max, etc.) for any numeric fields in a table. This allows rapid inspection of multiple fields without running separate geoprocessing tools or creating charts.

Create Field Statistics Chart (Option B) creates charts but is not as efficient for comparing multiple fields simultaneously.

Summary Statistics (Option C) creates grouped output tables but is more suitable for aggregation across rows, not across multiple fields.

The Project tool is used to permanently transform vector data from one coordinate system to another. It accurately applies transformation parameters between WGS 1984 and NAD 1983 UTM Zone 15N for feature classes such as hydrants (point data).

Define Projection only assigns a coordinate system when one is missing or incorrect; it does not transform coordinates.

Project Raster applies to raster datasets, not vector feature classes like hydrants.

Therefore, the correct answer is C.
