NEW QUESTION # 16
A GIS analyst is working with LAS data with 17 million points on the map. The points are too big and cover the underlying areas completely. The analyst needs to change the dimensions of the points.
Which action should the analyst take to meet this requirement?
- A. Decrease the symbol scale
- B. Increase the point density
- C. Decrease the display limit
Answer: A
Explanation:
Symbol scale determines the size of points when displayed. When LAS points appear too large, decreasing the symbol scale (making symbols smaller) will reduce the visual footprint of each point and prevent them from obscuring underlying map content.
* Increasing point density (Option A) adds more points but doesn't reduce size.
* Decreasing display limit (Option B) reduces how many points are drawn but does not solve the issue of size.
* Decreasing symbol scale directly reduces the size of each point.
Therefore, the correct answer is C.

NEW QUESTION # 17
A GIS analyst is trying to conduct overlay analysis using the Union tool but is unable to run the tool due to a red X in one of the parameters.
- A. The input features do not geometrically intersect.
- B. Both input features are not polygon feature classes.
- C. The environment settings for Processing Extent do not include the participating features.
Answer: C
Explanation:
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.
NEW QUESTION # 18
A GIS administrator receives reports from editors regarding schema locks on regularly updated enterprise data. Editors need to take turns editing, and project timelines are prolonged.
Which geodatabase capability will resolve this issue?
- A. Editor tracking
- B. Versioning
- C. Archiving
Answer: B
Explanation:
Versioning allows multiple editors to work simultaneously on the same dataset in an enterprise geodatabase without interfering with each other or encountering schema locks. Each editor works on a separate version, and changes can later be reconciled and posted.
* Archiving (Option A) tracks historical edits but does not address schema locks.
* Editor tracking (Option C) records who made changes and when, but does not resolve simultaneous editing conflicts.
Therefore, the correct answer is B.
NEW QUESTION # 19
Which workflow should be used to create a new dataset from a selection?
- A. In the Catalog pane > Export > Feature Class To Feature Class
- B. In the Contents pane > Layer > Data > Export Features
- C. In the Catalog pane > Export > Feature Class To Geodatabase
Answer: B
Explanation:
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.

NEW QUESTION # 20
A GIS analyst pulls in an image service from ArcGIS Online, which should contain a slope map, a hillshade map, an aspect map, a contour map, and a terrain map. However, the analyst only sees the terrain map.
How should the analyst access the other maps?
- A. Change band orders under symbology
- B. Change the source in the layer properties
- C. Switch to a different processing template in the layer properties
Answer: C
Explanation:
Many image services include multiple processing templates that provide different visualizations (e.g., slope, hillshade, aspect). The analyst can switch between these templates within the layer properties to access the various derivative products.
* Changing band order (Option A) affects multi-band imagery but won't expose separate processing templates.
* Changing the source (Option C) changes the entire dataset rather than switching between available templates.
Therefore, the correct answer is B.
NEW QUESTION # 21
A GIS specialist is creating a spatial map series for features that vary greatly in size.
Which scale bar Fitting Strategy will enable logical scale units specification and relative width among the varying maps?
- A. Adjust division value
- B. Adjust number of divisions
- C. Adjust width
Answer: C
Explanation:
The "Adjust width" fitting strategy automatically adjusts the physical width of the scale bar to fit the map scale. This ensures that the scale bar remains logical and proportional across maps of different extents in the map series.
* Adjust division value (Option A) modifies the distance represented by each division but may produce inconsistent scale bar sizes.
* Adjust number of divisions (Option C) changes the count of divisions rather than adjusting for proportional display across maps.
Therefore, the correct answer is B.
NEW QUESTION # 22
A GIS analyst receives a feature class with a unique date-time attribute. Each feature contains a single time field. Once the feature class is added to a map view, the layer can be time-enabled.
Which workflow should be used to enable the temporal attribute so that this layer can use the time slider?
- A. In the Layer Properties > from the Time tab
- B. In the Feature Class Properties > from the Source tab
- C. In the Map Properties > from the General tab
Answer: A
Explanation:
Time enabling a layer is done through the Layer Properties under the Time tab. This allows the analyst to specify the date-time field for use with the time slider, enabling temporal visualization directly in the map.
* Map Properties (Option B) does not handle time configuration for individual layers.
* Feature Class Properties (Option C) shows field details but does not enable time functionality.
Therefore, the correct answer is A.

NEW QUESTION # 23
In ArcGIS Pro, which type of unit of measure is always used for a vertical coordinate system?
- A. Angular units
- B. Direction units
- C. Linear units
Answer: C
Explanation:
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.
NEW QUESTION # 24
A GIS analyst is trying to buffer single point features one at a time within a feature class by interactively selecting it in a map before buffering. Multiple points are being selected, although one row in the attribute table is highlighted. The analyst does not want to modify the original data.
Which tool should be used to solve this issue?
- A. Split
- B. Multipart To Singlepart
- C. Explode
Answer: B
Explanation:
The Multipart To Singlepart tool separates multipart features into individual single-part features. This ensures that when selecting a feature, only the intended single feature is selected, rather than selecting multiple points grouped in a multipart feature.
* Explode (Option A) is not a valid geoprocessing tool for this scenario.
* Split (Option C) is used for dividing features, not separating multipart features.
Therefore, the correct answer is B.
NEW QUESTION # 25
Which workflow should be used to share a map as a TIFF file?
- A. Share > Capture To Clipboard
- B. Share > Export Map
- C. Share > Print Map
Answer: B
Explanation:
Export Map under the Share tab provides options to export maps into various formats, including TIFF, PDF, PNG, JPEG, and others. This is the standard workflow for creating a high-quality raster file suitable for sharing and archiving.
* Print Map (Option A) is for sending the map directly to a printer.
* Capture To Clipboard (Option C) copies the current map extent as an image to the clipboard for temporary use, not for file creation.
Therefore, the correct answer is B.

NEW QUESTION # 26
A GIS technician wants to perform spatial analysis for an area of interest extending in an east-to-west orientation. The technician needs to preserve the shape of the data.
Which projection should the technician use to minimize distortion?
- A. Hotine oblique Mercator
- B. Lambert conformal conic
- C. Transverse Mercator
Answer: B
Explanation:
Lambert Conformal Conic is best suited for regions that extend predominantly in an east-west direction. This projection minimizes distortion in shape (conformal property) for such areas and is widely used for mapping large areas like states, countries, or continents that are wider than they are tall.
* Transverse Mercator (Option A) is better for north-south-oriented regions.
* Hotine Oblique Mercator (Option C) is used for areas that are obliquely oriented along a particular great circle path.
Therefore, the correct answer is B.
-
NEW QUESTION # 27
A GIS technician working with 3D building data wants to interactively view only specific floors of a building at a time.
Which layer property allows for this type of visualization?
- A. Time
- B. Elevation
- C. Range
Answer: C
Explanation:
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.
NEW QUESTION # 28
In ArcGIS Pro, a GIS analyst adds a mosaic dataset to a map and notices that the entire mosaic area is covered with a black and white checkerboard.
Which tool should the analyst use to make the images visible in the map as part of the mosaic dataset?
- A. Repair Mosaic Dataset Paths
- B. Define Overviews
- C. Build Pyramids
Answer: A
Explanation:
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.
-
NEW QUESTION # 29
A GIS analyst wants to edit existing parcel data and separate a record into equal parts.
Which Modify Features editing tool should the analyst use to accomplish this task?
- A. Reshape
- B. Split
- C. Divide
Answer: C
Explanation:
The Divide tool is designed to split features into multiple equal parts. It supports dividing by area, count, or distance, making it ideal for tasks such as splitting parcels into equal-sized parts.
* Split (Option A) cuts features along a user-defined line but does not automatically create equal parts.
* Reshape (Option B) modifies feature boundaries but is not used to divide features into multiple parts.
Therefore, the correct answer is C.
-
NEW QUESTION # 30
A GIS analyst has a feature class and a non-spatial table stored in the same geodatabase. The analyst needs to create a composite relationship to ensure data integrity.
Which association type should the analyst apply?
- A. Attribute join
- B. Relationship class
- C. Spatial join
Answer: B
Explanation:
A relationship class defines a permanent association between a feature class and a table or between two feature classes in a geodatabase. Composite relationship classes enforce referential integrity, ensuring that related records remain consistent (e.g., when a parent record is deleted, related child records are also removed).
* Attribute join (Option A) is temporary and does not enforce integrity.
* Spatial join (Option B) requires spatial relationships and applies only between spatial datasets.
* Relationship class (Option C) allows managing relationships between spatial and non-spatial tables with referential integrity.
Therefore, the correct answer is C.
-
NEW QUESTION # 31
A GIS analyst wants to change the coordinate system of a hydrant dataset from WGS 1984 to NAD 1983 UTM Zone 15N.
Which tool will allow the data to be correctly transformed into the new coordinate system?
- A. Project
- B. Project Raster
- C. Define Projection
Answer: A
Explanation:
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.
-
NEW QUESTION # 32
A group of new GIS trainees must be trained on a specific workflow that includes zooming in to a specific area on a map, creating data, performing zonal statistics, extracting features, updating symbology, authoring a map layout, and exporting the layout into a PDF.
How should the instructor share the workflow to make sure that all steps are followed?
- A. Create a script in Jupyter Notebook and share the notebook
- B. Create and share a model as a toolbox
- C. Create and share a task as task file
Answer: C
Explanation:
Tasks in ArcGIS Pro are specifically designed to guide users through multi-step GIS workflows by packaging step-by-step instructions into a task file. This ensures trainees follow the workflow correctly and in sequence.
* Models (Option A) automate geoprocessing but do not guide interactive steps such as zooming, editing, or exporting layouts.
* Jupyter Notebooks (Option C) are suitable for scripting but not for guiding new users through step-by- step GUI-based tasks.
Therefore, the correct answer is B.
NEW QUESTION # 33
A GIS specialist has a feature class of flights that contains information such as origin city, destination city, and the length of time that the flight was delayed. The specialist needs to display this information in a chart and aggregate the delayed time as an average.
- A. Box plot
- B. Scatter plot
- C. Matrix heat chart
Answer: C
Explanation:
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).
NEW QUESTION # 34
A GIS analyst is trying to do some maintenance and clear up space as it relates to geodatabases while keeping editing capabilities intact.
Which tool should the analyst use?
- A. Compress File Geodatabase Data
- B. Compress
- C. Compact
Answer: C
Explanation:
In ArcGIS Pro, the Compact tool is designed to optimize the physical storage of file geodatabases by reducing disk space usage while fully preserving the ability to edit the data. Compact reorganizes how data is stored on disk but does not change or lock the data content or schema, allowing continued editing.
* Compress is used with enterprise geodatabases (versioned geodatabases) and primarily affects state-tree compression; it's not applicable to file geodatabases.
* Compress File Geodatabase Data is not an ArcGIS Pro tool; this option is invalid in this context.
* Compact is the proper tool for file geodatabase maintenance to reduce file size and fragmentation, while fully maintaining editability.
Therefore, the correct answer is C.
NEW QUESTION # 35
A GIS analyst performs an overlay operation between a city polygon layer and voting districts. The analyst observes multiple tiny slivers that are created because the boundaries of the city layer do not exactly overlap the boundaries of the voting district layer.
Which environment variable should the analyst use to avoid this in the future?
- A. Setting an M tolerance value
- B. Setting an XY tolerance
- C. Using cell alignment
Answer: B
Explanation:
XY Tolerance is used to control how close two vertices can be before they are considered the same point during processing. Setting an appropriate XY tolerance can prevent slivers caused by very small gaps or overlaps when performing overlay operations such as Intersect or Union.
* Cell alignment (Option B) is relevant for raster operations.
* M tolerance (Option C) applies to measures along linear features, not to spatial overlays of polygons.
Therefore, the correct answer is A.
