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?

• A. Write a Python script that imports urllib reads the data with uriopen and read methods and creates features from the data stream
• B. write a NET component that reads the data presents the data to ArcObjects as an x.v event and creates new features from the data source
• C. use a third party scraping application to copy the data to a local file and read it as an x, y event data source
• D. manually copy the file to local disk before running and run the Make XY Event Layer tool

An ArcGIS user has a custom .dll that reads the domains available in a geodatabase and compares them to business rules. What must the user do to have this tool run automatically each night?

• A. add the dll to a model and schedule the model through the Windows Task Scheduler
• B. create a stand-alone application to publish a service and schedule the application through the Windows Task Scheduler
• C. call the .dll within a Python script and schedule the script through the Windows Task Scheduler
• D. schedule the .dll to run in batch through the Windows Task Scheduler

A water utility company had received calls fromseveral customers complaining oflow water pressure.
Using a geometric network representing the water network, how can an ArcGIS user determine the most likely location of the problem?

• A. place junction flags on each customer water meter and use the Find Common Ancestors trace task
• B. place a junction barrier on each customer water meter and use the Trace Upstream trace task
• C. place a junction barrier on each customer water meter and use the Find Path upstream trace task
• D. place junction flags on each customer water meter and use the Find Disconnected trace task

An ArcGIS user wants to create a hierarchy and differentiate cities on a map by categorizing the way the features are labeled. What should be used to achieve the desired result?

• A. label priority
• B. label classes
• C. label stacking
• D. label expressions

A raster dataset called rasterl.tif contains many pixels with values of NoData.
Which map algebra expression changes NoData values to 0 (zero) in the output raster dataset while leaving all other pixel values the same?

• A. con(rasten.tif = NoData. 0 raster!, tif)
• B. con(setnull{raster1.tif), 0, rasterl.tif)
• C. con(rasten.tif = = NoData, 0, rasterl.tif)
• D. con(isnull(raster1.tif). 0, rasterl.tif)
