NEW QUESTION # 39
A GIS analyst must identify when and where bicycle accidents occur throughout a specific city within a one- year period. The data provided includes bicycle accidents for the entire state and spans a three-year period.
The analyst wants to limit visibility and geoprocessing to the features of interest.
Which workflow should the analyst follow?
- A. Apply a display filter to the layer
- B. Zoom to the study area in the map
- C. Apply a definition query to the layer
Answer: C
Explanation:
Definition queries limit the dataset used for both display and geoprocessing by applying SQL-based expressions to filter the data. This allows the GIS analyst to restrict all map display, analysis, and processing operations to only the records that meet the defined criteria (city and one-year period).
* Display filters only limit what is visually shown but do not impact geoprocessing.
* Zooming merely changes the map extent but has no filtering effect on data.
* Definition queries fully restrict the dataset for both visualization and processing.
Therefore, the correct answer is A.

NEW QUESTION # 40
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. Switch to a different processing template in the layer properties
- B. Change band orders under symbology
- C. Change the source in the layer properties
Answer: A
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 # 41
A GIS specialist needs to organize discontinuous imagery into a single dataset and wants to select individual rasters and download them when necessary.
Which dataset should be used to achieve this?
- A. LAS dataset
- B. Mosaic dataset
- C. Raster dataset
Answer: B
Explanation:
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.
NEW QUESTION # 42
An organization with many editors needs to know when features have been created and edited, as well as who edited the features.
Where should the GIS administrator enable this capability?
- A. The Manage options accessed by right-clicking the feature dataset
- B. The Manage options accessed by right-clicking geodatabase
- C. The Design options accessed by right-clicking the shapefile
Answer: A
Explanation:
Editor tracking (which records who edited a feature and when) is enabled on individual feature classes or feature datasets in a geodatabase under the Manage menu. Shapefiles do not support editor tracking.
* The geodatabase (Option A) controls higher-level administrative functions but not editor tracking.
* Shapefiles (Option B) do not support editor tracking.
* The feature dataset (Option C) allows enabling editor tracking for included feature classes.
Therefore, the correct answer is C.

NEW QUESTION # 43
An attribute table contains three columns with details of monthly rainfall for three consecutive years. A GIS analyst wants to compare the total rainfall, mean rainfall, and the minimum and maximum rainfall for each year.
Which tool should the analyst use to most efficiently compare this tabular data?
- A. Data Engineering view
- B. Create Field Statistics Chart
- C. Summary Statistics
Answer: A
Explanation:
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.
NEW QUESTION # 44
A GIS technician has crop field data and is working with a dimension feature class. The technician wants to get measurements for all features from the same starting location.
Which editing tool should the technician use to complete the task?
- A. Baseline aligned
- B. Continue dimensions
- C. Simple aligned
Answer: A
Explanation:
The Baseline Aligned dimension tool is used when multiple measurements need to originate from a common baseline. This is exactly the case when measuring multiple crop fields from the same starting location, ensuring consistent and aligned measurements across features.
* Simple Aligned creates individual dimension lines between two points but not aligned from a single baseline.
* Continue Dimensions adds dimensions that continue from the endpoint of the previous dimension but is not intended for measurements from a common baseline.
* Baseline Aligned properly anchors all measurements to the same origin point.
Therefore, the correct answer is B.
-
NEW QUESTION # 45
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 width
- B. Adjust number of divisions
- C. Adjust division value
Answer: A
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 # 46
In ArcGIS Pro, which type of unit of measure is always used for a vertical coordinate system?
- A. Direction units
- B. Angular 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 # 47
A GIS intern is digitizing water body features within a state park using Esri's Imagery basemap for reference.
While creating a lake feature, the intern realizes that they mistook a large portion of the lakefront as part of the lake.
Which editing tool should the intern use to modify the lake feature?
- A. Align Features
- B. Merge
- C. Reshape
Answer: C
Explanation:
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.
-
NEW QUESTION # 48
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. Compact
- B. Compress
- C. Compress File Geodatabase Data
Answer: A
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 # 49
Which tool should be used to set the coordinate system of a raster dataset that is currently unknown?
- A. Project
- B. Project Raster
- C. Define Projection
Answer: C
Explanation:
TheDefine Projectiontool is specifically used when a dataset lacks spatial reference metadata-that is, when its coordinate system is labeled as "Unknown." This situation arises when the coordinate system information is missing or was never assigned, and it is necessary to tell ArcGIS what spatial reference the data is already in without altering the data's location or pixel values.
According to ArcGIS Pro documentation and workflow best practices:
"The Define Projection tool assigns a coordinate system to a dataset that does not already have one. It does not alter the dataset's data or coordinate values-only the metadata is updated." This is crucial becauseProjectandProject Rasterare tools thattransformdata from one coordinate system to another, and they require that the data already has a valid defined coordinate system to begin with. Attempting to use either of those tools on data with an unknown projection would be incorrect and could lead to spatial inaccuracies.
Therefore, thecorrect and verified toolfor this situation isDefine Projection.
Reference Topics Covered:
* ArcGIS Pro - Data Management # Defining spatial reference
* ArcGIS Pro - Raster Functions and Georeferencing Workflows
* ArcGIS Pro - Geoprocessing Tool Help (Define Projection vs Project Raster)
* ArcGIS Pro Certification Study Guide - Data Management Domain
NEW QUESTION # 50
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. Divide
- C. Split
Answer: B
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 # 51
A GIS analyst works for a small city's GIS department, which uses the same projected coordinate system for all data. The analyst's common workflows often require geoprocessing tools that create new outputs of data on disk.
Which workflow will produce geoprocessing outputs with the desired coordinate system?
- A. Map Properties > Coordinate Systems tab > XY Coordinates Systems Available
- B. Analysis tab > Environments button > Output Coordinate System
- C. Project Settings Options > Map and Scene tab > Choose Spatial Reference
Answer: B
Explanation:
The Output Coordinate System environment setting under the Analysis tab controls the spatial reference for outputs created during geoprocessing. This ensures new output datasets automatically adopt the specified coordinate system during processing.
* Project Settings (Option A) control default map behavior but not geoprocessing outputs.
* Map Properties (Option C) sets the coordinate system for map display, not for output results.
Therefore, the correct answer is B.
-
NEW QUESTION # 52
Which ArcGIS Pro tab gives a user the option to export a map layout to a file?
- A. Project
- B. Map
- C. Share
Answer: C
Explanation:
The Share tab in ArcGIS Pro contains all options related to exporting maps, layouts, and sharing data. Export Layout options for formats like PDF, PNG, and others are found here.
* Project tab is used for application-level settings.
* Map tab is for map design and editing.
* Share tab includes all export and sharing options for layouts.
Therefore, the correct answer is C.
NEW QUESTION # 53
A GIS analyst is using the Raster Calculator to determine the best location to start a coffee tree farm. The soil should be deep sandy loam (represented by class code 5 in raster) or fertile volcanic red earth (class code 12).
Temperatures should remain between 17.8 to 21.1 degrees Celsius (64 and 70 degrees Fahrenheit), and the area should get at least 60 inches (1.52 meters) of rain per year.
Which expression should be used to produce suitable areas?
- A. (Precipitation>='60') & (Temperature <= '70') & (Temperature>='64') &((SoilType='5') & (SoilType='12'))
- B. ("Precipitation">=60) &(("SoilType"=5)|(SoilType=12)) &("Temperature" <= 70) &("Temperature"
>=64) - C. ("Temperature" <= 70) & ("Temperature">=64) & ("SoilType"=5) | (SoilType=12) &("Precipitation"
>=60)
Answer: B
Explanation:
The correct logical expression should:
* Use logical OR (|) for multiple acceptable soil types.
* Use logical AND (&) to combine precipitation, temperature, and soil criteria.
* Respect proper operator precedence with parentheses.
Option C correctly groups the conditions: precipitation # 60, temperature between 64 and 70, and soil type equal to either 5 or 12.
Therefore, the correct answer is C.

NEW QUESTION # 54
A land surveyor downloads an Excel sheet from the city website that contains the updated land cover codes with over 30 classes.
Which tool will help the surveyor update their existing land cover data to the new codes?
- A. Classify Raster
- B. Reclassify Field
- C. Reclass By Table
Answer: C
Explanation:
The Reclass By Table tool allows the surveyor to import a lookup table (such as an Excel sheet) that contains the old and new land cover codes. This is the most efficient method for batch reclassification when many classes are involved.
* Classify Raster (Option A) is used for unsupervised or supervised classification.
* Reclassify Field (Option C) is not a valid ArcGIS Pro tool for raster data reclassification.
Therefore, the correct answer is B.
NEW QUESTION # 55
A GIS technician is trying to publish an image service to their organization's portal. The technician needs to ensure service stability when rendering client-side by multiple coworkers at once.
Which capability should the technician specify when publishing?
- A. Processing templates
- B. Enable the WMS Service capability
- C. Maximum item size per request
Answer: C
Explanation:
Setting the Maximum Item Size Per Request controls how much data can be requested at one time, balancing server load and client-side rendering. Adjusting this value helps ensure stable performance for multiple concurrent users accessing large imagery datasets.
* Processing templates (Option A) define raster function chains but do not control service stability.
* WMS Service capability (Option C) allows publishing as a WMS service but does not directly address client-side stability for image services.
Therefore, the correct answer is B.
-
NEW QUESTION # 56
A GIS analyst needs to examine the metadata of a feature class not in the map to make sure the thumbnail graphic is current.
What is the recommended workflow to view the metadata feature class?
- A. In the Catalog pane, expand the geodatabase > Right-click the feature class > Select View Metadata
- B. In the Contents pane > Select the feature layer > From the View tab, click Catalog View
- C. In the Contents pane > Right-click the feature layer > Select View Metadata
Answer: A
Explanation:
The Catalog pane provides access to datasets not yet added to the map. From there, the user can right-click any dataset (including feature classes) and select View Metadata to view or edit metadata, including the thumbnail.
* The Contents pane only lists items already in the map.
* Catalog View (Option B) works if the dataset is already loaded into that view, but directly using the Catalog pane (Option C) is more efficient here.
Therefore, the correct answer is C.
-
NEW QUESTION # 57
A GIS analyst has a buildings feature class. The analyst needs to show the type of building, such as commercial or residential, and extrude the buildings based on height.
Which symbology type should the analyst use to produce the required output?
- A. Attribute-driven
- B. Dictionary
- C. Bivariate colors
Answer: A
Explanation:
Attribute-driven symbology allows different fields to control different aspects of visualization. In this case, one field (building type) can control color or symbol category, while another field (building height) controls the 3D extrusion. Attribute-driven symbology is designed specifically for this type of multi-attribute control.
* Bivariate colors (Option B) map two numeric fields into a color grid but do not control extrusion.
* Dictionary symbology (Option C) applies rule-based symbology often used for military or complex symbols, not 3D extrusion.
Therefore, the correct answer is A.
-
NEW QUESTION # 58
A GIS analyst receives a dataset of precipitation change over the past five years, by country, for the entire world. The analyst is creating a map that will display this information. A requirement of the map is to preserve the area of each country.
Which projection should be used?
- A. Robinson
- B. Equal Earth
- C. Mercator
Answer: B
Explanation:
The Equal Earth projection is specifically designed to preserve area across the globe, making it ideal for thematic mapping of global datasets like precipitation change by country. It balances accurate area representation with a visually pleasing appearance for world maps.
* Mercator (Option A) preserves angles but distorts area, especially near the poles.
* Robinson (Option C) is visually pleasing for world maps but distorts both shape and area.
Therefore, the correct answer is B.
-
NEW QUESTION # 59
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. Matrix heat chart
- C. Scatter plot
Answer: B
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 # 60
A GIS specialist is spending too much time editing text (for example, formatting and placement) associated with specific dynamic features in a series of maps they create regularly. The specialist wants to have fine- grain control of each feature's associated text.
Which method is most efficient?
- A. Annotation
- B. Text map notes
- C. Graphic text
Answer: A
Explanation:
Annotation allows for feature-linked or standard text placement with fine control over positioning, symbology, and formatting. It maintains a link to spatial features when necessary, ensuring consistent updates and control across multiple map products.
* Graphic text (Option A) is map layout-specific and not dynamic or feature-aware.
* Map notes (Option C) are simple text features often used for temporary mapping tasks and lack fine control for production mapping.
Therefore, the correct answer is B.
-
NEW QUESTION # 61
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. Explode
- B. Multipart To Singlepart
- C. Split
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.
