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.

In ArcGIS Pro, ared Xnext to a parameter in a geoprocessing tool typically indicates an invalid input due to conflicts with the current environment settings. One of the most common causes is when theProcessing Extentenvironment setting is configured in a way thatexcludesthe actual input features.

TheUniontool requires that input features fall within the set extent. If the Processing Extent does not cover any part of one or more input features, they are considered invalid and flagged with a red X, preventing the tool from running.

The software checks whether all input features are accessible within the defined extent. If they are not, this pre-validation error is triggered—even if the inputs are valid in terms of geometry or feature type.

Option A is incorrect because geometrical intersection is not a requirement for Union to run—it simply overlays features and includes all areas.

Option C is also incorrect, as the Union tool does indeed require polygon feature classes, but if incorrect feature types are used, a different error (not a red X related to extent) is shown.

This confirms that the red X in this scenario is caused by the Processing Extent settings not including the input features, making the correct answer B.

Project packages (.ppkx) contain all components of a project—including maps, layouts, database connections, styles, toolboxes, and models—making them ideal for sharing complete workspaces with coworkers who need access to everything.

Mobile map packages (Option A) are designed for offline use on mobile devices.

Map packages (Option B) include maps and data but do not include toolboxes, database connections, or project-level configurations.

Therefore, the correct answer is C.

In ArcGIS Pro, geographic (datum) transformations for on-the-fly projection are managed at the map level. This ensures that all layers added to the map are projected correctly into the map’s coordinate system, applying the appropriate transformation as needed.

Layer Properties (Option A) displays information for the specific layer but does not set map-level transformations.

Project Options (Option B) relates to overall software settings, not coordinate system transformations.

Map Properties (Option C) contains the Coordinate Systems tab where transformations can be set.

Therefore, the correct answer is C.

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.

Topology in ArcGIS Pro requires a geodatabase feature dataset. Shapefiles do not support topology directly. Therefore, the shapefile must first be converted to a feature class within a feature dataset in a geodatabase. Topology can then be created and applied.

Options A and B are incorrect because topology cannot be applied directly to file folders or shapefiles.

Therefore, the correct answer is C.

The Reshape tool allows you to modify an existing polygon’s shape by drawing a new boundary for part of the feature. This is ideal for correcting over-digitized areas by trimming or extending specific portions of the lake.

Merge (Option B) combines multiple features but doesn’t reshape geometry.

Align Features (Option C) is used for snapping and aligning edges between features but not for altering individual shapes.

Therefore, the correct answer is A.
