Question 1

A contractor delivers a shapefile whose stored coordinates are verified NAD 1983 UTM Zone 15N eastings and northings in meters. Its spatial-reference metadata incorrectly identifies the coordinates as WGS 1984 longitude and latitude. The required deliverable is in NAD 1983 UTM Zone 15N, and the coordinate values themselves are correct. What should the analyst do first?

Accepted Answer

Use Define Projection to assign NAD 1983 UTM Zone 15N to the shapefile.

Answer

Use Project to convert from WGS 1984 to NAD 1983 UTM Zone 15N.

Answer

Change the map's coordinate system to NAD 1983 UTM Zone 15N.

Answer

Apply a WGS 1984-to-NAD 1983 geographic transformation to the shapefile's coordinates.

Question 2

During a wildfire evacuation, planners need a drivable route from each assembly point to its fastest reachable shelter. Every shelter has sufficient capacity. The road network has current travel times and one-way restrictions; the only new condition is a confirmed bridge closure. Temporary restriction barriers are supported. Which configuration should drive the routing decision?

Accepted Answer

Closest Facility from assembly-point incidents to shelter facilities, using travel time and a restriction barrier on the bridge.

Answer

Closest Facility from shelter facilities to assembly-point incidents, using travel time and a restriction barrier on the bridge.

Answer

Closest Facility from assembly-point incidents to shelter facilities, using travel distance and a restriction barrier on the bridge.

Answer

Suspend route solving until the closed bridge is removed from the source road features and the network dataset is rebuilt.

Question 3

Two annual maps show vacant housing as a percentage of all housing units in the same districts. Definitions and boundaries are unchanged, but the annual data ranges differ. Each map uses five independently calculated Natural Breaks classes and the same light-to-dark ramp. A district with 12% vacancy in both years changes color. The maps must compare actual percentages, not relative rankings. How can the author ensure that a given percentage has the same color in both maps?

Accepted Answer

Use matching manual class breaks and color assignments for both years.

Answer

Use five Quantile classes calculated independently for each year.

Answer

Use five Equal Interval classes spanning each year's own data range.

Answer

Use Standard Deviation classes based on each year's mean and standard deviation.

Question 4

The permitted Material/Diameter_mm combinations for a pipe feature class are PVC/100, PVC/150, steel/150, and steel/200. The class is already subtyped by network role, which must remain unchanged. Material and Diameter_mm currently have independent coded-value domains. Editors need the diameter choices narrowed when they select a material, not merely an error after committing an incompatible pair. How should this dependency be implemented?

Accepted Answer

Create a field group with contingent values for the permitted Material and Diameter_mm combinations.

Answer

Reject incompatible pairs with a constraint attribute rule triggered when an edit is committed.

Answer

Use a 100-to-200 range domain for diameter and retain the material domain.

Answer

Assign diameter domains to the existing network-role subtypes, leaving material choices independent.

Question 5

A utility wants authorized browser users to update asset attributes in the same enterprise geodatabase used by its ArcGIS Pro editors. The enterprise data must remain authoritative; scheduled transfers between separate copies are not acceptable. Registration with the federated server, server access, and editing privileges are already in place. Select the publication strategy that meets these requirements.

Accepted Answer

Publish an editable web feature layer that references the registered enterprise data.

Answer

Publish an editable hosted copy, refreshed from enterprise data after each editing shift.

Answer

Publish an editable hosted copy with sync enabled.

Answer

Publish only a map image layer referencing enterprise data, with attribute pop-ups in the web map.

Question 6

An ArcPy script classifies readings in an editable file-geodatabase feature class. FLOW_LPS is a nullable numeric field, and READING_STATUS is a text field. A flow of zero is a valid measurement; only null means that no measurement was taken. The code runs, but valid zero readings are marked Missing.

import arcpy

with arcpy.da.UpdateCursor(assets, ["FLOW_LPS", "READING_STATUS"]) as cursor:
    for row in cursor:
        if row[0]:
            row[1] = "Measured"
        else:
            row[1] = "Missing"
        cursor.updateRow(row)

The variable assets contains a valid dataset path. Which replacement for the if line corrects the classification without changing the rest of the script?

Accepted Answer

if row[0] is not None:

Answer

if row[0] != 0:

Answer

if row[0] is not None and row[0] > 0:

Answer

if row[0] is not None or row[0] != 0:

Question 7

An overlay review shows the following:
Original census polygon: 2,400 residents; area 6.0 square kilometers.
Flooded fragments: two nonoverlapping areas of 0.6 and 0.9 square kilometers; each retains POPULATION = 2400.

The areas were calculated appropriately. With no address-level population data available, the approved planning method assumes residents are uniformly distributed within the original polygon. Which total belongs in the summary of the flooded portion?

Accepted Answer

600 residents, as an area-weighted estimate rather than an observed headcount.

Answer

300 residents, by averaging the two fragments' apportioned populations.

Answer

2,400 residents, by keeping a single copy of the source count.

Answer

4,800 residents, from summing the unchanged original population attributes of both flooded fragments.

Question 8

Surveyed roof points store z-values as elevations above a vertical datum, not as heights above ground. A local scene uses the same datum and meter units. The layer is set to Relative to the ground with no additional offset. Its symbols float above their surveyed positions by approximately the local terrain elevation, which varies across the site. What single change corrects the display without altering the surveyed z-values?

Accepted Answer

Use At an absolute height, taking heights from geometry z-values.

Answer

Apply a constant negative cartographic offset to the ground-relative layer.

Answer

Set On the ground and derive point elevations from terrain.

Answer

Use Relative to a custom surface with the same bare-earth DEM.

Question 9

A public web map must let anonymous visitors query current roadwork locations, work types, and expected completion dates. The source hosted feature layer also contains contractor contact details that must remain restricted. Authorized staff must continue editing the full source, and public values must reflect those edits without maintaining a second dataset. The item owner has approved release of the three public attributes. Which arrangement satisfies the access requirements?

Accepted Answer

Expose approved attributes through a public, read-only hosted feature layer view; leave its source restricted.

Answer

Make the source layer public, disable editing, and remove the contractor contact details from every web-map pop-up.

Answer

Keep the source layer restricted and make only the referencing web map public, with its field list limited to approved attributes.

Answer

Publish a separate public feature layer containing approved fields, and refresh that copied layer through a scheduled export from the source.

Question 10

A vacancy-rate analysis produces two results: Global Moran's I is not significant at the selected 0.05 level (p = 0.24), while Cluster and Outlier Analysis reports one tract as HL after false discovery rate correction. The local result is statistically significant, and its neighborhood definition has been checked. A reviewer proposes suppressing the tract because the global test was not significant. What interpretation is defensible?

Accepted Answer

The tract has high vacancy among low-vacancy neighbors; global nonsignificance does not rule out a significant local outlier.

Answer

HL identifies a high-vacancy cluster: both the tract and its neighbors have high values.

Answer

HL indicates low vacancy in the tract surrounded by high-vacancy neighbors.

Answer

The tract should remain unclassified; a nonsignificant global result prevents any local pattern from being reported as statistically significant.
