An ArcGIS user needs to create a map of flood zones for an insurance company. The user has a choice of four elevation data sets to perform the analysis

• A.USGS 30 meter DEM
• B.USGS 30-meter DEM
  * SRTM 90-meter DEM
  * Lidar 5-meter DEM
  * 30-meter DEM derived from stereo imagery
  Which type of elevation dataset will create the most accurate flood zones?
• C.30-meter DEM derived from stereo imagery
• D.Lidar5-meter DEM
• E.SRTM 90 meter DEM

AnArcGIS user is tasked with editing a layer containing a large number of features, using another layer thatis in a different coordinate a system as reference. The user adds the layers in ArcMap and starts an editsession. A warning message about editing data in a different coordinate system is displayed.
What is the most efficient way to edit the data to avoid potential distortion in the data?

• A.georeference the reference layer and start a new edit session
• B.change the data frame's coordinate system to match the coordinate system of the layer being edited
• C.project the reference layer so the coordinate system matches with the one that needs to be edited
• D.create a geodatabase topology with the two layers and add a rule so new data always snaps to thereference layer

An ArcGIS user has a soils polygon shapefile
Which conversion is necessary in order to ensure that the soil polygons do NOT overlap or have gaps?

• A.converting the shapefile to a stand-alone polygon feature class within a geodatabase
• B.converting the shapefile to a raster dataset within the geodatabase
• C.converting the shapefile to a terrain dataset with the geodatabase
• D.converting the shapefile to a polygon=feature class within a geodatabase feature dataset

Refer to the exhibit.

Which change needs to be made to the table in the exhibit in order to create subtypes based on the CFCC field?

• A.The data type of the CFCC field should be changed to Long integer
• B.A new field should be created to migrate the text values of CFCC to integers
• C.A default CFCC value should be assigned
• D.The allow subtypes property should be set to True

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