NEW QUESTION # 11
A GIS technician wants to share one layer from their map as a feature service to a portal.
Which workflow should the technician use to accomplish this task?
- A. Click the Share tab > Web Layer > Publish Web Layer
- B. Right-click the layer > Sharing > Share As Layer Package
- C. Right-click the layer > Sharing > Share As Web Layer
Answer: C
Explanation:
Right-clicking the specific layer and selecting "Share As Web Layer" allows the technician to directly publish that individual layer as a feature service to a portal. This avoids sharing the entire map or unrelated layers.
* Share tab > Web Layer (Option A) is used for sharing multiple layers but is less direct for single-layer publishing.
* Layer Package (Option B) creates a package for sharing offline, not a web feature service.
Therefore, the correct answer is C.
NEW QUESTION # 12
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. Zoom to the study area in the map
- B. Apply a definition query to the layer
- C. Apply a display filter to the layer
Answer: B
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 # 13
A GIS specialist works for an electric company that is planning tree maintenance along power lines. The specialist wants to associate tree features with a geometry of "Point" and the power lines feature class in the utility network dataset with a geometry of "Polyline Z." All trees, regardless of height, should be joined if they are in the specified vicinity of the power lines.
- A. Within Clementini
- B. Within a distance
- C. Within a distance 3D
Answer: B
Explanation:
TheSpatial Jointool in ArcGIS Pro allows specifying aMatch Optionthat defines how spatial relationships between feature geometries are evaluated. In this scenario, the target and join features are of different geometry types-Points (trees) and Polylines (power lines)-so the appropriate match options are based on proximity rather than containment or other spatial relations.
* Within a distance: Matches features based on a planar search radius, ignoring elevation (Z-value), making it ideal for cases where all trees within a certain horizontal distance from power lines should be included, regardless of height.
* Within a distance 3D: Includes vertical (Z) differences in the search, which is unnecessary here since tree height shouldn't affect inclusion.
* Within Clementini: Refers to a topological boundary relationship and is only valid for comparisons involving polygons-not points vs polylines.
Thus, to includeall trees within a specified horizontal buffer of the power lines, theWithin a distance option is the correct one.
NEW QUESTION # 14
Which raster format can ArcGIS Pro display but not write?
- A. MrSID
- B. GIF
- C. IMAGINE Image
Answer: A
Explanation:
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.

NEW QUESTION # 15
A land-use classified raster with nine different classes needs to be resampled from 10 x 10 m to 30 x 30 m cell size. The resample tool must be used, and the land classes must be preserved.
Which resampling technique should be used?
- A. Bilinear
- B. Nearest
- C. Cubic
Answer: B
Explanation:
For categorical (classified) rasters such as land-use data, Nearest Neighbor interpolation must be used during resampling. This technique preserves the original class values without introducing fractional or interpolated values.
* Cubic (Option A) and Bilinear (Option B) are interpolation methods suited for continuous data (elevation, temperature, etc.), but will distort categorical data.
Therefore, the correct answer is C.
-
NEW QUESTION # 16
A GIS analyst has over 100 rasters of the same resolution and dimension. The analyst needs to combine all rasters into one raster so that it is easier to share with other analysts who need to perform analysis on the raster (s).
What should the analyst do?
- A. Create a mosaic dataset and share it on a thumb drive
- B. Use the Mosaic To New Raster geoprocessing tool and share
- C. Publish the rasters as a tile layer and share the link to the layer
Answer: B
Explanation:
The Mosaic To New Raster tool merges multiple input raster datasets into a single raster dataset in a file- based format. This approach simplifies sharing and analysis because the result is a single raster file rather than a collection of rasters. Since all rasters have the same resolution and dimension, this tool is the most efficient solution for permanent combination.
* Mosaic Datasets (Option A) are great for managing large raster collections but remain as collections, not single files.
* Publishing tile layers (Option C) is primarily for web sharing, not file-based sharing or analysis.
Therefore, the correct answer is B.
NEW QUESTION # 17
A GIS analyst is about to run analysis using multiple feature layers from the current map. They want to do one final check to ensure which feature classes do and do not have definition queries as expected.
How should the analyst check this most efficiently?
- A. Right-click layer in Contents > Properties > Definition Query
- B. Select layers in Contents > Feature Layer - Data tab > Definition Query
- C. Contents pane > Filter > Active Definition Query
Answer: C
Explanation:
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.

NEW QUESTION # 18
A GIS technician wants to use raster functions to quickly visualize optimal positioning for solar panels based on a digital elevation model. Requirements state that for the area of interest, the panels must face north.
Additionally, flatter terrain is preferred.
Which function(s) will allow for the quickest visualization of these factors?
- A. Curvature, Slope
- B. Aspect-Slope
- C. Shaded Relief
Answer: B
Explanation:
The Aspect-Slope function combines slope and aspect information from a DEM to help identify ideal orientations and slope conditions for solar panel placement. Since north-facing panels and flatter slopes are required, this function directly provides both variables together for quick visualization.
* Curvature, Slope (Option A) would show slope steepness and surface curvature but not directionality (aspect).
* Shaded Relief (Option B) is only for visual hillshading and does not provide aspect or slope data.
Therefore, the correct answer is C.
-
NEW QUESTION # 19
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 # 20
A GIS analyst has two datasets: Students and School Districts. The analyst wants to assign a school district to each student based on where the student lives.
Which tool should be used to accomplish this task?
- A. Summarize Within
- B. Enrich
- C. Spatial Join
Answer: C
Explanation:
Spatial Join allows you to assign attributes from one layer (School Districts) to features in another layer (Students) based on spatial relationships such as containment or proximity.
* Enrich (Option B) adds demographic or socioeconomic data but is not used for spatial assignment of existing features.
* Summarize Within (Option C) aggregates data within polygons but does not assign attributes to point features.
Therefore, the correct answer is A.
-
NEW QUESTION # 21
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. Versioning
- B. Editor tracking
- C. Archiving
Answer: A
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 # 22
A GIS technician has two feature classes: Sites and Buildings. The technician needs to assign the building name to the site if they intersect when adding/updating site features and wants to use attribute rules to do this.
Which attribute rule type should the analyst use to accomplish this task?
- A. Calculation rule
- B. Validation rule
- C. Constraint rule
Answer: A
Explanation:
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.
-
NEW QUESTION # 23
A cartographer is authoring a layout that currently includes one map and would like to provide additional context by adding another map to the layout.
Which action should the cartographer perform in the layout view?
- A. Add a new map view.
- B. Add a new layout.
- C. Add a new map frame.
Answer: C
Explanation:
A map frame is a container in the layout that displays any map or scene. To add a second map for additional context, the cartographer should insert a new map frame and choose which map it will display. This allows multiple maps to be shown together on the same layout.
* Map view (Option B) refers to a separate view in the interface, not to the printed layout.
* New layout (Option C) creates an entirely separate layout rather than adding to the current one.
Therefore, the correct answer is A.
-
NEW QUESTION # 24
A GIS technician creates a domain that will be used in a feature class where field workers will specify the species of tree when they perform an inspection. The technician made some mistakes and needs to edit the domain.
What can the technician edit?
- A. Domain type
- B. Codes and values
- C. Field type
Answer: B
Explanation:
After a domain is created, the codes and values (descriptions) can be edited to correct or update the domain entries. However, the field type and domain type (range or coded value) cannot be changed once the domain has been applied to a dataset.
* Field type (Option A) cannot be modified after creation.
* Domain type (Option C) also cannot be changed after creation.
Therefore, the correct answer is B.
-
NEW QUESTION # 25
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 task as task file
- C. Create and share a model as a toolbox
Answer: B
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 # 26
A GIS analyst has an electrical line feature class that contains attributes such as wire gauge and amperage.
The analyst wants to limit acceptable values during the editing process for amperage based on the choice of wire gauge.
Which type of attribute rule should be used?
- A. Constraint rule
- B. Validation rule
- C. Calculation rule
Answer: A
Explanation:
Constraint rules prevent invalid data entry during editing. In this case, a constraint rule ensures that only valid amperage values are allowed based on the chosen wire gauge. If an invalid amperage is entered, the rule will block the edit and display an error message.
* Calculation rule (Option A) automatically calculates values but doesn't prevent invalid inputs.
* Validation rule (Option C) flags invalid data but doesn't prevent edits from being saved.
Therefore, the correct answer is B.
-
NEW QUESTION # 27
A GIS analyst receives a project and data from a colleague. When opening the project, the analyst notices that the data links are broken. All the data is located in the same folder, and the analyst wants to repair all the broken links simultaneously.
Which workflow should the analyst use?
- A. View > Catalog View > Data Sources > Item > New Path > Apply
- B. Right-click the layer > Properties > Source > Set Data Source
- C. Click the red exclamation point > Change Data Source
Answer: A
Explanation:
The Data Sources tab in the Catalog View allows the analyst to repair multiple broken data paths simultaneously by assigning a new folder location. This is the most efficient way to repair multiple broken links at once.
* Set Data Source (Option A) and Change Data Source (Option B) only repair one layer at a time.
* Catalog View > Data Sources (Option C) supports batch repairs.
Therefore, the correct answer is C.
-
NEW QUESTION # 28
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 Map Properties > from the General tab
- B. In the Feature Class Properties > from the Source tab
- C. In the Layer Properties > from the Time tab
Answer: C
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 # 29
A GIS technician has two feature classes: Sites and Buildings. The technician needs to assign the building name to the site if they intersect when adding/updating site features and wants to use attribute rules to do this.
Which attribute rule type should the analyst use to accomplish this task?
- A. Calculation rule
- B. Validation rule
- C. Constraint rule
Answer: A
Explanation:
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.
NEW QUESTION # 30
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. Build Pyramids
- B. Define Overviews
- C. Repair Mosaic Dataset Paths
Answer: C
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 # 31
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.
