An ArcGIS user is tasked with publishing an image service out of a collection of rectified satellite imagery. Building the Image service definition results In a rotated dataset with large areas of NoData on the comers. The ArcGIS user needs to recompute the footprints to remove the large areas of NoData on the edges. Which method of recomputing footprints accomplishes this?

A. by geometry

B. by radiometry

C. by clipping

D. by related geometry

An ArcGIS user wants to make a map displaying the data using an equal number of features in each classification. Which classification method should the user employ to accomplish this?

A. equal Interval

B. natural breaks (Jenks)

C. quantile

D. standard deviation

An ArcGIS user receives a model to buffer the weekly crime point features. The users organization has established a standard for symbolizing all buffers using a layer file. The user copies and runs the model on a local machine. The resulting

output buffer uses default symbology.

Why do the output buffers use the default symbology?

A. The layer file uses relative paths

B. The layer file is NOT appearing in the map

C. The model variable was NOT updated

D. The model variable CANNOT be shared

A. smooth curve

B. simplify

C. add control points

D. cut curve

An ArcGIS user is creating a script tool to automate a common workflow.

Which tool property ensures that the tool only recognizes intended feature data sources?

A. output spatial reference property

B. data type fitter property

C. workspace data property

D. data extent property

An analyst has a multi band raster, but needs just one of the bands for a project. Which geoprocessing tool should be used to extract a single band?

A. Slice (3D Analyst)

B. Extract by Attributes (Spatial Analyst)

C. Composite Bands (Data Management)

D. Clip (Data Management)

An ArcGIS user is given a geodatabase and tasked with adding a feature class to an existing geodatabase topology. What should the user do?

B. modify the existing geodatabase topology to include the feature class Explanation:- https://desktop.arcgisxom/en/arcmap/10.3/tools/data-m

C. export the existing geodatabase topology to an XML file include the feature class in the XML and import it

D. remove all the feature classes from existing topology and add everything back including the feature class that needs to be added

A tax preparation company completes a quarterly cleaning of their records. Using a Python script they automate the deletion of records that are more than seven years old or records for customers who have not been seen in more than five years.

When using a cursor function, what deletes the appropriate records?

A. a search cursor and the deleteRow method

B. an insert cursor and the deleteRow method

C. an update cursor and the deleteRow method

D. a find cursor and the deleteRow method

Using the Spatial Analyst IDW (Inverse Distance Weighted) tool an ArcGlS user interpolates a point feature class to a raster. The user notices that some high point values near the edge of the feature class seem to have a dramatic effect on the output.

This occurs even in areas that are far from the high edge values.

Which two parameters should the user consider changing in the IDW tool? (Choose two)

A. z-value field

B. search radius

C. power

D. output cell size

E. weight

After the ground water is the local community was contaminated by a landfill, the health department requested a map showing the cancer rate for each postal code. An ArcGlS user Is provided a file geodatabase feature class (FeatureClassA) that has been joined to a cancer rate table (TableB). The cancer rate table does not have data for each postal code In the study and also contains data outside the study area creating null values. To eliminate the null values from being symbolized.

Which exclusion query should be used?

A. (FeatureClassA OBJECTED is Not Null) and (TableB.cancerrate Is Not Null)

B. ("FeatureClassA OBJECTED" is Not Null) and (TableB.cancerrate is Not Null)

C. ("FeatureClassA OBJECTED". "TableB cancerrate" is Not Null)

D. ("FeatureClassA OBJECTED" and "TableB cancerrate" is Not Null)
