NEW QUESTION # 45
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 # 46
A GIS analyst is assigned to update an existing roads feature class (line features) with new features and information obtained from a third-party agency. However, the column names in the new feature class and the old feature class do not match.
Which geoprocessing tool should the analyst use to update the old feature class by correctly matching the columns?
- A. Union with 'Attributes To Join' set as 'All Attributes'
- B. Append with 'Schema Type' as 'Test'
- C. Append with 'Schema Type' as 'No_Test'
Answer: B
Explanation:
Using the Append tool with Schema Type set to 'Test' ensures that fields in both datasets match before appending. This allows the analyst to verify that fields align correctly and prevents mismatched data from being incorrectly merged.
* 'No_Test' (Option B) appends records regardless of schema mismatch, which is risky here.
* Union (Option C) combines geometries, not designed for updating attribute schemas.
Therefore, the correct answer is A.
NEW QUESTION # 47
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. Use the Mosaic To New Raster geoprocessing tool and share
- B. Publish the rasters as a tile layer and share the link to the layer
- C. Create a mosaic dataset and share it on a thumb drive
Answer: A
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 # 48
An organization that manages vector data as shapefiles wants to use topology rules for editing data.
What should be the initial steps to implement topology?
- A. In the Catalog pane, right-click the file folder that the shapefile resides in > Point to New > Topology
- B. Open the Create Topology geoprocessing tool > For Input Feature Dataset, select the file folder that the shapefile resides in > Name the topology and run tool
- C. Convert the shapefile to a geodatabase feature class in a feature dataset > Right-click the feature dataset
> Point to New > Topology
Answer: C
Explanation:
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.
NEW QUESTION # 49
A GIS analyst is publishing data that they will use for field collection and to inspect existing assets.
Which type of layer should be shared?
- A. Vector tile layer
- B. Web tile layer
- C. Web feature layer
Answer: C
Explanation:
Web feature layers support both visualization and editing (including field collection). They allow field crews to update, add, or inspect asset information in real-time or while working offline.
* Web tile layer (Option B) and Vector tile layer (Option C) support visualization only and do not support editing or inspection of feature attributes.
Therefore, the correct answer is A.
-
NEW QUESTION # 50
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. Calculation rule
- C. Validation 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 # 51
A GIS technician has a feature class that contains thousands of features. The technician needs to control when certain features within the feature class draw on the map as they zoom in or out.
Which method should be used to accomplish this?
- A. Definition query
- B. Visibility range
- C. Display filters
Answer: B
Explanation:
Visibility range (also called scale range) controls at what zoom levels a layer or features are displayed. This allows the map to automatically hide features when zoomed out too far, improving performance and reducing clutter, while showing detailed features as the user zooms in.
* Definition query (Option A) filters features based on attribute values, not map scale.
* Display filters (Option C) filter features at specific scales but require advanced configuration; visibility range is more direct for simple scale-based drawing control.
Therefore, the correct answer is B.
-
NEW QUESTION # 52
A GIS specialist is publishing a layer to their portal for use by field crews. These crews will not always have internet connection. They need to edit existing features based on inspections, but they should not be able to delete features.
How should the layer be configured to support the field crews?
- A. Enable editing > Allow editors to update feature attributes only > Check Enable Sync
- B. Enable editing > Allow editors to add features only > Check Enable Sync
- C. Enable editing > Allow editors to update feature attributes only > Check Export Data
Answer: A
Explanation:
Enable Sync allows offline editing by field crews. Setting the editing options to allow editors to update feature attributes only ensures that field staff can modify existing records but not delete them. This configuration supports disconnected editing while preserving data integrity.
* Export Data (Option B) enables data export but does not support offline sync editing workflows.
* Add features only (Option C) would prevent the crews from updating existing features, which is part of their task.
Therefore, the correct answer is A.
NEW QUESTION # 53
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. Divide
- B. Reshape
- C. Split
Answer: A
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 # 54
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 environment settings for Processing Extent do not include the participating features.
- B. Both input features are not polygon feature classes.
- C. The input features do not geometrically intersect.
Answer: A
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 # 55
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 a distance
- B. Within Clementini
- C. Within a distance 3D
Answer: A
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 # 56
In ArcGIS Pro, which tool should be used to change the coordinate system of a dataset to a different coordinate system?
- A. Project
- B. Convert Coordinate Notation
- C. Define Projection
Answer: A
Explanation:
The Project tool is used to permanently convert data from one coordinate system to another, recalculating coordinates to match the new spatial reference.
* Define Projection assigns a spatial reference to datasets that do not have one but does not transform coordinates.
* Convert Coordinate Notation converts coordinate formats (such as MGRS, UTM, DMS) but not spatial references.
Therefore, the correct answer is B.
-
NEW QUESTION # 57
Where can geographic transformations be set when projecting on-the-fly?
- A. Map Properties
- B. Project Options
- C. Layer Properties
Answer: A
Explanation:
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.

NEW QUESTION # 58
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. Maximum item size per request
- B. Processing templates
- C. Enable the WMS Service capability
Answer: A
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 # 59
A GIS analyst has a standalone table that includes the change in population by county and a layer of counties.
Which method should the GIS analyst use to visualize the change using symbology?
- A. Join the table and layer based on the county field.
- B. Add a spatial join between the table and layer.
- C. Relate the table and layer based on the county field.
Answer: A
Explanation:
To visualize population change, the attribute (change in population) must be accessible to the county feature layer's symbology engine. A Join operation adds the table fields directly to the feature layer's attribute table based on a common key (county field), making the data available for symbology classification.
* Relate creates a temporary relationship but does not merge data for symbology purposes.
* Spatial Join is used when spatial relationships are needed; here, the relationship is attribute-based.
* Join correctly allows the standalone table values to drive symbology on the spatial features.
Therefore, the correct answer is B.
