An ArcGIS user wants to create a tool that reads a Web data source from the U.S. Geological Survey site and create a feature class of earthquakes over magnitude 1 that have occurred in the last seven days. The data source URL is a .txt file directly usable as x, v event data, once downloaded.

The goal is to have a repeatable process to be run on demand overwriting the output each time with minimal user input and easy to understand for other users to whom the tool is provided

What should the user do to read and process the data?

An ArcGlS user has a point feature class and needs to determine whether there are anyspatial outliers. For this project, a spatial outlier is defined as any feature that is greater than one standard deviation from the mean center of the features.

Which Spatial Statistics geoprocessing tool should be used to accomplish this task?

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

A geometric network has been removed from a feature dataset.

What must happen to the geodatabase to avoid synchronization failing?

An ArcGiS user wants to dynamically generalize a line using the Douglas-Peucker algorithm. Which geometric effect should be used to achieve this?

The ArcGlS user is given data for the Arctic and is asked to perform various types of analysis using the data. The data extend from the North pole south to 70 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.

Given known petroleum reserves in the Arctic, plus areas reserved for endangered species habitat the user must determine the area In square miles that is available for oil extraction development for the United States.

Which protection is best suited for this analysis?

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?

An ArcGIS user requests polygon parcel data to use in a model linking geoprocessing tools. The data the user receives covets the entire country and the large dataset causes the application to perform slowly.

How can the ArcGIS user improve the performance time without altering the model?

An ArcGlS user maintains a street signpost database with measure in terms of two route feature classes: distance from the nearest school and distance along the street.

If the two feature classes are created from the same source line feature class, which geoprocessing tool will support calculating one event from the other?

An ArsGIS user has a Python script to synchronize a geodatabase with large numbers of updates from the server. Why does the ArcGIS user benefit from scheduling the synchronization process through Task Scheduler?
