Esri EADP19-001 問題集

質問 1：
Refer to the exhibits.


An ArcGIS user is attempting to create a relationship class between the two tables shown in the exhibit using POSTAL_CODE and Zip Code as the origin primary key and destination foreign Keys, respectively. However when the user tries to set the keys zip Cede does not appear in the drop-down list of candidate keys What should the user do to successfully create the relationship class?
A. change the relationship type from non attributed to attributed
B. make sure both tables are in the same geodatabase
C. create data type compatible key fields
D. move both tables to the same feature dataset
正解：B

質問 2：
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 highway passes under a surface street) What should be used to ensure that the road casings connect correctly?
A. symbol-level drawing with the merge option
B. symbol-level drawing with the join option
C. multi-layered symbol with one layer wider than the other
D. single layered symbol with two offset lines
正解：B

質問 3：
An ArcGIS user is given a geodatabase containing polygon and point features.
To ensure that the points fall on the boundary, which topology rule should the user set?
A. Polygon Contains One Point
B. Point Musi Be Covered By Boundary Of Polygon
C. Polygon Contains Point
D. Point Must Be Properly inside Polygons
正解：B

質問 4：
Given an elevation surface, a raster of forest stands, and a point feature class of saw mills, which analysis is used to determine the optimal route from each forest stand to the nearest saw mill?
A. Viewing
B. Network
C. Proximity
D. Distance
正解：D

質問 5：
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 polygon=feature class within a geodatabase feature dataset
B. converting the shapefile to a terrain dataset with the geodatabase
C. converting the shapefile to a stand-alone polygon feature class within a geodatabase
D. converting the shapefile to a raster dataset within the geodatabase
正解：A

質問 6：
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. change the data frame's coordinate system to match the coordinate system of the layer being edited
B. georeference the reference layer and start a new edit session
C. create a geodatabase topology with the two layers and add a rule so new data always snaps to thereference layer
D. project the reference layer so the coordinate system matches with the one that needs to be edited
正解：A

質問 7：
An ArcGlS user is given a populated geodatabase thai contains a few highly accurate feature classes and a few feature classes that are less accurate.
When designing a geodatabase topology, which coordinate rank should be assigned to feature classes of less accuracy when compared with feature classes of higher accuracy?
A. rank them the same as highly accurate feature classes so their coordinates are adjusted to weighted average
B. rank them higher so the coordinates of highly accurate feature classes are adjusted
C. rank them higher so their coordinates are not adjusted
D. rank them lower so their coordinates are adjusted to highly accurate feature classes
正解：D

質問 8：
An ArcGiS user wants to dynamically generalize a line using the Douglas-Peucker algorithm. Which geometric effect should be used to achieve this?
A. simplify
B. add control points
C. cut curve
D. smooth curve
正解：A

質問 9：
An ArcGIS user adds two feature classes with different coordinate systems in ArcMap. one at a time. The user starts editing data from the second feature class and is warned about editing the feature class because the coordinate system is different from the data frame.
Where do the edits occur?
A. In the data frame's coordinate system
B. In the feature's coordinate system
C. In an azimuthal equidistant coordinate system
D. In a geographic coordinate system
正解：A
