Esri EADP19-001 問題集

質問 1：
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 NET component that reads the data presents the data to ArcObjects as an x.v event and creates new features from the data source
B. Write a Python script that imports urllib reads the data with uriopen and read methods and creates features from the data stream
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
正解：B

質問 2：
Four emergency response facilities need to be placed so that the greatest number of people in a community can be reached within five minutes.
Which analysis method is used to make this determination?
A. Dufer
B. location allocation
C. closest facility
D. route
正解：B

質問 3：
A tax preparation company completes a quarterly cleaning of their records. Using a Python script they automate the deletion of records that are more than seven years old or records for customers who have not been seen in more than five years.
When using a cursor function, what deletes the appropriate records?
A. an insert cursor and the deleteRow method
B. an update cursor and the deleteRow method
C. a search cursor and the deleteRow method
D. a find cursor and the deleteRow method
正解：B

質問 4：
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 5：
An ArcGIS user is writing a Python script that will update the geometry of all the features of an input layer using a process that requires system tools to examine the geometric properties of each feature.
Which approach should be used to evaluate each feature's geometry and pass it to a system tool?
A. open an update cursor on the input layer and read its shapes as geometry objects that can be used as system tool inputs
B. open an update cursor on the input layer and make in_memory feature classes for each feature that can be used as system tool inputs
C. make feature layers from a selection o' each input geometry that can be used as system tool inputs
D. export input feature geometries to OGC WKT (OpenGIS Well Known Text) values in a spatial database and use OpenOIS spatial operators to calculate new geometries
正解：B

質問 6：
When designing a geometric network where should the feature classes be stored?
A. inside a topology
B. outside a feature dataset
C. inside a single feature dataset
D. inside any feature datasets sharing the same spatial reference
正解：C

質問 7：
An ArcGIS user downloads shapefiles from a Web site. The metadata on the Web site Indicates that the spatial reference the same as that used in the user's workplace, but the downloads draw southwest of the user's data and the downloaded data appears too small.
What is the most likely cause of the alignment problem?
A. The latitude of origin from the metadata is incorrect
B. The central meridian from the metadata is incorrect
C. The metadata refers to an incorrect datum
D. The linear units referred to in the metadata are incorrect
正解：D

質問 8：
Refer to the exhibit.

An ArcGIS user added a new street (shown in the exhibit) to a streets feature class within an edit session.
The new street seems to have snapped to an existing street but upon zooming in the ArcGIS user notices that the street is connected to the wrong street.
What is the most likely reason for this error?
A. Edge snapping was turned on Instead of end snapping
B. The street was digitized at a scale that was too small
C. The snapping tolerance was set to Low
D. The street was digitized at a scale that was too large
正解：A

質問 9：
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. Slops sending change messages
C. Resends change messages
D. Discards the change messages
正解：C
