ESRI ArcGIS Desktop Certification Exam – Practice Exam
Questions with Correct Verified Answers/ Latest 2026.
1. When creating a feature class to store elevation values
collected along a hiking trail in the field, what must be done?
A) Set the tolerance to greater than 0.001
B) Add a field called Elevation and make the geometry type
Double
C) Assign the feature class a projected coordinate system in units
of meters
D) Make the feature class z-enabled
Answer: D
Rationale: To store elevation (z-values) along a linear feature, the
feature class must be z-enabled to support 3D data. Z-values allow
for the representation of elevation or height information along the
trail .

,2. What is the maximum length for a file geodatabase name in
ArcGIS Desktop?
A) No limit
B) Limited to 32 characters
C) Limited to 255 characters
D) Limited to the number of characters the operating system
allows in a folder name
Answer: C
Rationale: File geodatabase names are limited to 255 characters,
which is the same as the maximum file name length in Windows
operating systems .
3. Which of the following is NOT a method to create a new file
geodatabase in ArcGIS Desktop?
A) Create a new file geodatabase in ArcCatalog
B) Use the New File Geodatabase tool from the Editor toolbar
C) Use the Command Line window
2
,D) Use the Create File GDB tool in ArcToolbox
E) Create a file geodatabase in Windows Explorer
F) Use Python to create a File GDB
Answer: B
Rationale: The Editor toolbar does not contain a "New File
Geodatabase" tool. File geodatabases can be created through
ArcCatalog, the Command Line window, the Create File GDB
geoprocessing tool, Windows Explorer (by creating a folder with a
.gdb extension), or using Python .
4. Which coordinate system is appropriate for storing a
worldwide scale dataset using measures of latitude and
longitude, while also allowing for the data to be easily projected
for editing and analysis at a local level?
A) Universal Transverse Mercator (UTM)
B) Geographic Coordinate System (GCS)
C) Geocentric Coordinate System
3
, D) Projected Coordinate System
Answer: B
Rationale: A Geographic Coordinate System (GCS) uses latitude
and longitude to store data on a 3D sphere. This is appropriate for
worldwide datasets and allows for easy projection to local
coordinate systems for analysis and editing .
5. When is a transformation required while projecting data?
A) When the input data source is a network
B) When the input and output geographic coordinate systems are
different
C) When the input and output spatial references are different
D) When the input feature class has an unknown spatial
reference
Answer: B
Rationale: A geographic/datum transformation is required when
projecting data between different geographic coordinate systems
