1A developer wants to publish a CSV of store locations as a hosted feature layer in ArcGIS Online so it can be queried and edited through the REST API. Which workflow correctly produces a hosted feature layer?
A.Add the CSV as an item to the portal, then publish it as a hosted feature layer
B.Reference the CSV directly from the Maps SDK without adding it to the portal
C.Convert the CSV to a tile package and host it as a vector tile layer
D.Upload the CSV to a public web server and link to it as an image service
Explanation: Hosting data in ArcGIS Online means uploading the source (such as a CSV) as an item and then publishing that item, which creates a hosted feature layer with a queryable, editable REST endpoint. The publish step copies the data into Esri-managed storage and generates the feature service.
2When data is published as a hosted feature layer in ArcGIS Online, where does the underlying feature data physically reside?
A.On the developer's local machine, streamed on demand
B.In Esri-managed cloud storage associated with the organization
C.Only in the client browser cache after first load
D.In a separate Pearson VUE data center
Explanation: Publishing a hosted feature layer copies the data into Esri-managed cloud infrastructure tied to the ArcGIS Online organization. Esri stores, indexes, and serves the data, which is why hosting consumes storage credits in ArcGIS Online or Location Platform.
3A developer needs a fast-drawing, read-only background layer of polygons that will not change and must render quickly at many scales. Which hosted layer type is most appropriate?
A.OGC WFS stream layer
B.Hosted feature layer with editing enabled
C.Hosted vector tile layer
D.Hosted table with no geometry
Explanation: A hosted vector tile layer serves pre-generated, cached vector tiles that draw very quickly across scales and are ideal for stable, read-only basemap or reference content. Because tiles are cached, the data is not edited live but renders efficiently.
4Which statement best distinguishes a feature layer from an imagery (image) layer in ArcGIS?
A.A feature layer is always raster; an imagery layer is always vector
B.Both store only tabular attributes with no spatial component
C.A feature layer can only be 3D; an imagery layer can only be 2D
D.A feature layer stores vector geometry and attributes; an imagery layer stores raster pixel data
Explanation: Feature layers represent discrete vector features (points, lines, polygons) with attribute tables, while imagery layers serve continuous raster pixel data such as aerial photos or satellite imagery. Choosing the correct data type is fundamental to designing an ArcGIS solution.
5An organization wants to expose a hosted feature layer so applications can request only the features within a map's current extent. Which capability of the feature service supports this?
A.Spatial query filtering by geometry/envelope
B.Static file download of the entire dataset only
C.Print service rendering
D.Tile caching of imagery pyramids
Explanation: Feature services support spatial queries that filter returned features by a geometry or envelope, so an app can request only features intersecting the current map extent. This reduces payload size and improves performance in client applications.
6A developer publishes a map image layer (dynamic map service) instead of a hosted feature layer. What is the primary functional characteristic of a map image layer?
A.It returns individual editable features as JSON for client-side rendering
B.It renders map images on the server and returns them to the client as pictures
C.It can only serve elevation data for 3D scenes
D.It stores no symbology and cannot be styled
Explanation: A map image layer (dynamic map service) draws the map on the server using the service's symbology and returns rendered images to the client. This is useful for complex cartography or large datasets where server-side rendering is preferable to sending raw features.
7In ArcGIS Online, what is the relationship between an 'item' and a hosted feature 'service'?
A.The service is metadata only; the item holds all the data
B.An item can never reference a hosted service
C.The item is the portal entry that points to and describes the underlying service
D.The item and the service are completely unrelated objects
Explanation: In a portal, an item is the catalog entry (with title, thumbnail, sharing, and a URL) that references the underlying service endpoint. The hosted feature service provides the actual REST functionality, while the item is how users discover and manage it.
8A developer wants to publish a web service from a desktop project. Which Esri product is typically used to author and publish hosted web layers to a portal from the desktop?
A.ArcGIS Dashboards
B.ArcGIS StoryMaps
C.ArcGIS Survey123
D.ArcGIS Pro
Explanation: ArcGIS Pro is the primary desktop application for authoring maps and data and publishing them as web layers and web services to ArcGIS Online or ArcGIS Enterprise. The publish workflow in Pro shares maps, feature layers, tile layers, and more to the portal.
9Which file/data type is correctly matched to its typical use in ArcGIS Online publishing?
A.Shapefile (.zip) published as a hosted feature layer
B.Vector tile package published as an editable point feature layer
C.CSV published as a 3D elevation surface
D.GeoTIFF published as a non-spatial hosted table
Explanation: A zipped shapefile is a common upload that ArcGIS Online publishes as a hosted feature layer, preserving vector geometry and attributes. Matching source formats to the correct output layer type is a core content-management skill.
10A hosted feature layer must support attribute updates submitted from a custom web app. Which feature service capability must be enabled?
A.Tile caching
B.Editing
C.Static export only
D.Synchronous print
Explanation: To allow a client app to add, update, or delete features and attributes, the hosted feature layer must have the Editing capability enabled on the feature service. Without it, the layer is read-only and applyEdits requests will fail.
