If an organization wants to share multiple maps and scenes to an external user, what type of package should they use?

The correct choice in this scenario is to use a project package. A project package allows an organization to consolidate multiple maps, scenes, and all associated resources into a single, portable file. This makes it ideal for sharing comprehensive geographic information with external users, as it can include various elements like layers, tools, and layout information that are essential for understanding and utilizing the shared content.

Using a project package ensures that all elements are bundled together, preserving the context and functionality of the maps and scenes being shared. This organization of data is particularly beneficial when external users need to access not just individual maps or layers but an entire project that may include various components interlinked with one another.

In contrast, the other types of packages focus on more specific aspects of GIS content: a map package generally includes a single map and its associated layers, a layer package pertains only to a specific layer with its data, and a geoprocessing package is designed for sharing tools and their workflows. None of these options would adequately convey the complete array of maps and scenes to an external user as effectively as a project package would.
