EAPA_2025 Dumps with Practice Exam Questions Answers

Mosaic datasets manage collections of multiple rasters, including discontinuous imagery, without physically merging the data. They allow users to query, subset, and download individual rasters on demand while maintaining a single logical dataset.

Raster dataset (Option A) stores a single continuous raster.

LAS dataset (Option B) is specific to lidar point cloud data.

Therefore, the correct answer is C.

ArcGIS Pro’sMatrix Heat Chartis designed for visualizing relationships between two categorical fields—such as origin and destination cities—and summarizing a numeric field, like delay time, using aggregate functions (e.g., mean). This type of chart aligns perfectly with the requirement:

It allows you to setColumnto the destination city andRowto the origin city.

Then choose theNumberfield as delay time and theAggregationmethod as "Mean" to calculate average delay.

The chart displays each origin‑destination pair as a cell, color‑coded by the calculated average delay.

Official documentation highlights this example explicitly:

“Create a matrix heat chart to identify the flights that have the highest average arrival delay time between origin and destination city by setting the following properties… Aggregation—Mean; Number—DelayTime”

Other chart types don’t fit the requirement:

Box plotis used to display distributions and identify outliers; it doesn’t aggregate by category pairs.

Scatter plotshows relationships between numeric variables on a continuous axis—not suitable for categorical city‑pair aggregation.

Therefore, the most appropriate choice for summarizing average journey delay by city pairs is theMatrix Heat Chart (C).

When you have selected features in a map layer and want to create a new dataset containing only those selected features, the proper workflow is to right-click the layer in the Contents pane, go to Data > Export Features. This process honors the current selection set and creates a new feature class based on that selection.

The Catalog pane (Options A and C) exports entire datasets and doesn’t apply the selection set directly.

Export Features (Option B) directly works with selected features and generates a new dataset from them.

Therefore, the correct answer is B.

Vertical coordinate systems always use linear units to measure elevation or depth (e.g., meters, feet). This differs from horizontal coordinate systems, which may use angular units (degrees) for geographic coordinates.

Angular units (Option B) apply to latitude and longitude in horizontal systems.

Direction units (Option C) apply to bearings or azimuths, not elevation.

Therefore, the correct answer is A.

The correct SQL expression should filter parcels that are both in the North region and where the OwnerName field contains 'Jon.' The LIKE operator is appropriate when matching patterns or partial names.

Option A correctly combines both conditions using AND.

Option B would include any parcel in the North region or any parcel where OwnerName contains Jon, which is overly broad.

Option C incorrectly uses exact equality, which would fail to match variations like 'Johnson' or 'Jonas.'

Note: The LIKE expression typically includes wildcard characters (e.g., LIKE '%Jon%') but based on provided options, Option A represents the correct logic.

Therefore, the correct answer is A.
