ESRI: GETTING STARTED WITH GEODATABASE
TOPOLOGY EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED LATEST UPDATE
cluster tolerance - (answers)The minimum tolerated distance between vertices in
a topology. Vertices that fall within the set cluster tolerance are snapped together
during the topology validation process.
cracking - (answers)In ArcGIS, a part of the topology validation process in which
vertices are created at the intersection of feature edges.
dirty areas - (answers)Regions surrounding features that have been altered after
the initial topology validation process and require additional topology validation
to be performed to find any errors.
edge - (answers)A line between two points that forms a boundary. In a geometric
shape, an edge forms the boundary between two faces. In topology, an edge
defines lines or polygon boundaries.
exception - (answers)An error that is an acceptable violation of a topology rule. In
ArcMap, for example, a cul-de-sac is a legitimate exception to the rule that
prohibits dangles.
node - (answers)In a geodatabase, the point representing the beginning or ending
point of an edge, topologically linked to all the edges that meet there.

relationship - (answers)An association or link between two objects in a database.
Relationships can exist between spatial objects (features), between nonspatial
objects (rows in a table), or between spatial and nonspatial objects.
topology - (answers)In geodatabases, the arrangement that constrains how point,
line, and polygon features share geometry. For example, street centerlines and
census blocks share geometry, and adjacent soil polygons share geometry.
Topology defines and enforces data integrity rules (for example, there should be
no gaps between polygons).
topology rule - (answers)An instruction to the geodatabase defining the
permissible relationships of features within a given feature class or between
features in two different feature classes.
validation - (answers)From old course: The process of comparing the topology
rules against the features in a dataset. Features that violate the rules are marked
as error features. Topology validation is typically performed after the initial
topology rules have been defined, after the feature classes have been modified,
or if additional feature classes or rules have been added to the map topology.
validation rule - (answers)A rule applied to objects in the geodatabase to ensure
that their state is consistent with the system that the database is modeling. The
geodatabase supports attribute, connectivity, relationship, and custom validation
rules.
