ESRI GIS EXAM QUESTIONS AND
ANSWERS
Which two data checks could you use when analyzing a road network to ensure
that all of the roads are straight lines with 90-degree angles? - ANSWER The
two checks that would meet these criteria are Nonlinear Segment and Cutbacks.
The Nonlinear Segment check examines each segment of a polyline or polygon
feature to see if it contains curves or arcs. The Cutbacks check allows you to set
a minimum permissible angle; any angle less than that will be noted as an error.
Data Quality Requirement Every tree feature must have a coded value that
identifies its species. - Domain for answering questions
Road routes may not contain two or more vertices with the same mileage
measurement. - ANSWER Monotonicity
Sidewalks may not meet building parcels—ANSWER feature on the feature.
When a feature fails a data validation check, how does ArcGIS Data Reviewer
tackle the problem? - ANSWER Flags the error till it's resolved.
An analyst applies many reviewer rules to a dataset. What step does the analyst
need to take before starting an automatic validation review? - ANSWER Add an
error layer to the map.
A city planning department's data quality criteria states that property parcels
must not overlap. Which data validation check will meet this requirement? -
ANSWER Feature On Features
