An ArcGIS user receives a drawing file created in AutoCAD, and is told the data is in NAD 1983 State Plane coordinates. When compared with data for the same area, the .dwg file is too big.

An ArcGIS user in a county office receives a large volume of data In shapefiles, coverages and table formats. The user is responsible for converting the data to a standard feature class format and writing it into a central enterprise geodatabase. The data must be simultaneously available for editing and spatial analysis tasks.

How should the Windows Task Scheduler be used to achieve these goals?

A. schedule to run a geoprocessing service with (he [asks and maintain log of script validation errors

B. schedule to run a geoprocessing service with the tasks and allocate a specific lime to run each task in the service

C. patch the tasks in a script and schedule to run the script at a scheduled time at non- peak hours

D. patch the tasks In a model and schedule to run the model at a scheduled time at non- peak hours

A taster contains pixels with decimal values.

Which method is used to round raster pixel values to the nearest whole number?

A. use the Round Up tool (Spatial Analyst), then the Round Down tool (Spatial Analyst)

B. use the Round Down tool (Spatial Analyst), then the Round Up tool (Spatial Analyst)

C. use the Plus tool (Spatial Analyst) to add 1. then the Minus tool (Spatial Analyst) to subtract 0.5

D. use the Plus tool (Spatial Analyst) to add 0.5, then the int tool (Spatial Analyst) to truncate to the nearest integer

An ArcGIS user wants to symbolize the intersections of highways and streets so that the road casing symbols can be blended together to represent connectivity, but not blended in other situations to represent disconnectivity (e.g. where a

A. symbol-level drawing with the join option

B. symbol-level drawing with the merge option

C. multi-layered symbol with one layer wider than the other
