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.power
• B.weight
• C.search radius
• D.z-value field
• E.output cell size

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

In a disconnected environment a data receiver fails to send acknowledgement messages often enough. How will the data sender respond?

• A.sends the next change messages
• B.Resends change messages
• C.Discards the change messages
• D.Slops sending change messages

ArcGIS user is updating all the newly paved roads after some recent constructions. The snapping tolerance is set to 15 pixels. They zoom out to the full extent to see their progress.
What should the ArcGIS user do next to maintain the accuracy of their editing?

• A.increase the sticky move tolerance
• B.return to the previous scale
• C.increase the snapping tolerance
• D.increase the thickness of the roads

Refer to the exhibit.

The ArcGIS user is given data for the Arctic, and is asked to perform various types of analysis using the data.
The data extends from the North Pole south to 55 degrees North Latitude Data layers may contain points lines, or polygons and include ice surveys from NOAA depth contours; continental margins, locations of known and suspected oil reserves, endangered species habitat and territorial boundaries for nations having Arctic coastline.
An ArcGIS user is asked to calculate the distance a cruise ship will travel through open water, departing from Nome, Alaska, with stops at Point Barrow Alaska Churchill Manitoba St John's Newfoundland and ending in Bar Harbor Maine. On the basis of these calculations the cruise ship line will determine fuel requirements and travel time.
Which map projection yields the most accurate results for this distance calculation?

• A.Mercator
• B.azimuthal equidistant
• C.Lambert azimuthal
• D.Albers equal area conic
