Esri EAEP2201 Practice Exam Questions & Answers

After federating a GIS Server with the portal and registering a relational data store, the next step is to designate the GIS Server as the hosting server in the ArcGIS Enterprise portal. This configuration enables the portal to support the publishing of hosted feature layers and hosted scene layers. The hosting server must have both a relational data store and a tile cache data store configured to support these functionalities.

The Spatiotemporal big data store is designed for massive datasets and optimized for high-speed visualization, time-enabled querying, and big data analytics. It is ideal for storing millions of point features such as sensors or oil rig locations, especially when performance and scalability are critical.

From ArcGIS documentation:

''The spatiotemporal big data store is designed for writing and querying large volumes of spatial and temporal data. It's optimized for visualizing high-density datasets in web maps.''

Option B (Relational) works for moderate data volumes but may not scale well.

Option C supports cached tiles, not dynamic feature access.

The GIS Professional user type includes access to ArcGIS Pro, which is required for creating print layouts, charts, animations, and conducting advanced analysis. It also includes capabilities such as creating groups, editing features, and creating web apps within the ArcGIS Enterprise portal---without needing additional add-on licenses.

The Creator user type supports most web GIS tasks but does not include ArcGIS Pro unless an add-on license is assigned. The Editor user type is the most limited and is intended for editing existing content only, not for creating or managing groups or web applications.

The standard feature analysis tools in ArcGIS Enterprise (e.g., buffer, overlay, aggregate points) require hosted feature layers, which depend on the relational data store (a component of ArcGIS Data Store). The relational data store is the default location for hosting feature layers.

From ArcGIS Enterprise documentation:

''To use the standard spatial analysis tools and create hosted feature layers, the ArcGIS Data Store (relational) must be configured and set as the default hosting location.''

Option A (spatiotemporal big data store) is used for real-time and big data feeds, not standard analysis.

Option C supports cached tiles, not feature layers.

To allow users to add new features without the ability to modify or delete existing ones, the feature service should have the 'Create' and 'Query' operations enabled. The 'Create' operation permits users to add new features, while the 'Query' operation allows them to view existing features. By not enabling the 'Update' and 'Delete' operations, users are restricted from making changes to or removing existing features. This configuration is ideal for workflows where data integrity is crucial, and only the addition of new data is permitted.

Enabling 'Update and sync' (Option A) would allow users to modify existing features and synchronize changes, which is not desired in this scenario. 'Extract and create' (Option C) is not a standard combination of operations for controlling editing permissions in feature services.
