NEW QUESTION # 39
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. ("Temperature" <= 70) & ("Temperature">=64) & ("SoilType"=5) | (SoilType=12) &("Precipitation"
>=60) - C. ("Precipitation">=60) &(("SoilType"=5)|(SoilType=12)) &("Temperature" <= 70) &("Temperature"
>=64)
Answer: C
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 # 40
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 Design options accessed by right-clicking the shapefile
- C. The Manage options accessed by right-clicking geodatabase
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 # 41
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 # 42
A GIS analyst has a countrywide parcel dataset and needs to determine the property owners for the northern region of the country. The analyst wants to find owners whose last name contains Jon.
Which query should the analyst use?
- A. Region = 'North' AND OwnerName LIKE 'Jon'
- B. Region = 'North' AND OwnerName = 'Jon'
- C. Region = 'North' OR OwnerName LIKE 'Jon'
Answer: A
Explanation:
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.

NEW QUESTION # 43
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 # 44
A GIS analyst has three elevation rasters from which to create a mosaic dataset. The maximum elevation is
1,200 ft, and the minimum elevation is 300 ft. After the mosaic dataset is created and the values are inspected in the table of contents, the maximum and minimum elevation value are shown to be 3.48e+38 and 3.48e-38 respectively.
What is causing this issue?
- A. Statistics are missing.
- B. The color balance is wrong.
- C. Overviews are not defined.
Answer: A
Explanation:
The extremely large and small values (3.48e+38 and 3.48e-38) indicate that valid statistics (min and max values) have not been calculated for the mosaic dataset. Without statistics, ArcGIS assigns default extreme placeholder values. Running the "Build Statistics" tool will calculate the correct min and max elevation values.
* Color balance (Option A) affects display but not data statistics.
* Overviews (Option C) improve display performance but do not affect statistics calculation.
Therefore, the correct answer is B.

NEW QUESTION # 45
A GIS analyst needs to conduct overlay analysis between two feature classes. All input features must be kept while pulling over only the attributes of the second feature class where geometric intersection exists.
Which tool will provide the expected result?
- A. Intersect
- B. Union
- C. Identity
Answer: C
Explanation:
The Identity tool retains all features from the first input layer and transfers attributes from the second input layer only where intersections occur. This ensures all original features remain while appending intersecting attributes.
* Intersect (Option A) keeps only overlapping areas.
* Union (Option C) keeps all features and all attributes, regardless of intersection.
Therefore, the correct answer is B.
-
NEW QUESTION # 46
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 # 47
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. Constraint rule
- C. Validation 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 # 48
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. Spatial Join
- B. Summarize Within
- C. Enrich
Answer: A
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 # 49
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 3D
- C. Within a distance
Answer: C
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 # 50
A GIS analyst needs to build a workflow that extracts the required bands on a raster, uses the NDVI function on the extracted bands, and assigns a colormap to the resulting raster on the fly. The analyst is then required to share the tools in the right order with the team.
How should the analyst share the workflow?
- A. Create a model using ModelBuilder and share a toolbox
- B. Create a processing template and share it as an XML file
- C. Write a Python script for the workflow and share the script
Answer: B
Explanation:
Raster function processing templates (shared as XML files) allow for chaining multiple raster functions (such as band extraction, NDVI calculation, and colormap assignment) into a single, shareable processing workflow that executes on-the-fly. This is highly efficient for imagery workflows.
* ModelBuilder (Option B) is better for general geoprocessing workflows but not as optimized for on-the- fly raster processing.
* Python scripts (Option C) provide automation but may require more technical expertise to implement and maintain.
Therefore, the correct answer is A.
-
NEW QUESTION # 51
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 # 52
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. Display filters
- B. Definition query
- C. Visibility range
Answer: C
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 # 53
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.
