• Question 54:

  A GIS administrator wants to share map documents with other staff who have access to the administrator's drive. The administrator does NOT want staff to have to copy the data to their local drives to open the map documents. The administrator must change the local system paths to UNIC paths in all map documents.

  How should the GIS administrator accomplish the task?

  A. Use a Python script to find and replace workspace paths.

  B. In ArcCatalog, rename the databases and data folders.

  C. In ArcMap, Save A Copy to a new location.

  D. From the Contents pane, click the red exclamation points to fix the data sources.

  Correct Answer: C

• Question 55:

  A GIS analyst using ArcGIS Pro needs to georeference several non-georeferenced aerial photos. All aerial photos have a similar spectral signature, the same geographic location, time and season, image orientation, image scale, and band combination. The analyst has a single georeferenced raster in a known coordinate system for the same location, which has the same image properties. The analyst adds the single georeferenced raster to a new map with an imagery basemap layer and then applies the following workflow:

  Imagery tab > Georeference > Prepare group > Fit To Display > Adjustment group

  Which next step allows the analyst to georeference the remaining non-georeferenced aerial photos?

  A. Auto Georeference

  B. Add Control Points

  C. Import Control Points

  D. Transform

  Correct Answer: A

• Question 56:

  Which ready-to-use-service can be utilized in ArcGIS Desktop for network analysis?

  A. Elevation

  B. Logistics

  C. Hydro

  D. Geocoding

  Correct Answer: B

• Question 57:

  A GIS analyst creates a model that includes a Python script to process non-spatial data for use in several of the model steps. The model needs to be shared with online users who must be able to modify, add additional data, and execute the model locally on their own desktops.

  How should the GIS analyst share the script and model?

  A. Web tool

  B. Geoprocessing package

  C. Project package

  D. Python toolbox

  Correct Answer: B

• Question 58:

  How can two shapefiles be combined into a new feature class in a file geodatabase?

  A. Use the Append tool with schema type TEST on a feature class in geodatabase

  B. Export the shapefiles to a new file geodatabase

  C. Use the Merge tool to merge the shapefiles into a feature class

  D. Use the Append tool with schema type NO_TEST on a feature class in a geodatabase

  Correct Answer: B

• Question 59:

  Which workflow in ArcGIS Pro will most efficiently load all feature classes, subtypes, and domains from a previously exported personal geodatabase to a file geodatabase?

  A. Import Replica Schema

  B. Copy features

  C. Feature Class To Feature Class

  D. Import XML workspace document

  Correct Answer: B

• Question 60:

  After being provided with 2 TB of aerial imagery from a vendor, an analyst must use the imagery to build a single dataset to be consumed within ArcGIS Desktop. However, the analyst must NOT duplicate any of the imagery due to storage constraints.
