Question 1

A region of spatial proximity computed around one or more objects in a layer is a:&#10;A) Polyline&#10;B) Focus&#10;C) Dissolved Region&#10;D) Buffer

Accepted Answer

A buffer is a region of spatial proximity computed around one or more objects in a layer, typically used in geographic information systems (GIS) to create areas within a certain distance from a geographic feature.

Question 2

Which of the following geoprocessing tools will extract the features of one layer based on the shapes of features in a second layer?&#10;A) Clip&#10;B) Identity&#10;C) Dissolve&#10;D) Symmetrical Difference

Accepted Answer

The Clip tool extracts features from one layer using the shapes of features in another layer as a boundary.

Question 3

Which of the following geoprocessing tools will combine two or more layers together into a pre-existing layer?&#10;A) Merge&#10;B) Append&#10;C) Union&#10;D) Intersect

Accepted Answer

Append is the correct geoprocessing tool for combining two or more layers together into a pre-existing layer, adding the data from the input layers to the existing layer without creating a new layer.

Question 4

Geoprocessing options that control activities in a map document are:&#10;A) Document settings&#10;B) Tool settings&#10;C) Control settings&#10;D) Environment settings

Accepted Answer

Environment settings in GIS software like ArcGIS control various aspects of how geoprocessing tasks are executed, including the workspace, output coordinate system, and processing extent, among others. These settings ensure that geoprocessing operations are performed consistently and according to the user's specific requirements for a project.

Question 5

The Update geoprocessing operation will:&#10;A) Append the new layer on top of an existing layer&#10;B) Edit the existing layer so that all features now have topology&#10;C) Remove the area under the boundary of the new layer from the existing layer&#10;D) Take an existing layer and separate it into two or more newly updated layers

Accepted Answer

The answer of The Update geoprocessing operation will:&#10;A) Append the...

Question 6

Which of the following geoprocessing tools will retain all the features from the first layer along with the features it has in common with the second layer?&#10;A) Clip&#10;B) Identity&#10;C) Dissolve&#10;D) Symmetrical Difference

Accepted Answer

The Identity tool retains all features from the first input layer and adds the attributes from the overlapping features of the second input layer. This operation is similar to a spatial join where all features of the first layer are preserved, including those that do not overlap with the second layer, but it also includes the attributes from overlapping features of the second layer.

Question 7

The Symmetrical Difference geoprocessing operation will:&#10;A) Preserve all features that two layers have in common with each other&#10;B) Preserve all the features of one layer and all of the features of a second layer&#10;C) Preserve all the features of one layer and all of the features of a second layer except for the areas that they have in common&#10;D) Preserve all the features of one layer and all of the features that a second layer has in common with the first layer

Accepted Answer

The Symmetrical Difference geoprocessing operation preserves all the features of one layer and all the features of a second layer except for the areas that they have in common, effectively combining the unique areas of both layers.

Question 8

The end result of a point-in-polygon overlay is:&#10;A) A new point layer with the polygon attributes joined to the points that fall within that polygon&#10;B) A new polygon layer that identifies how many points fall within each polygon&#10;C) A new polygon layer that contains all of the point attributes associated with each polygon&#10;D) A new point layer that contains the coordinates of the bounding polygon for each point

Accepted Answer

A point-in-polygon overlay operation typically results in a new point layer where each point retains its original attributes, with the addition of the attributes of the polygon it falls within. This allows for the analysis of point data in the context of the spatial areas defined by the polygons.

Question 9

Which of the following geoprocessing tools will retain all the features of both layers?&#10;A) Merge&#10;B) Append&#10;C) Union&#10;D) Intersect

Accepted Answer

Union retains all features and attributes of both input layers, combining them into a single layer where both sets of features are preserved, including areas where they overlap.

Question 10

The scripting language used for ArcGIS is:&#10;A) Alice&#10;B) Silverlight&#10;C) Javascript&#10;D) Python

Accepted Answer

Python is the primary scripting language used for ArcGIS, enabling automation of tasks and the extension of ArcGIS functionalities through scripting.
