To prevent confusion among users who do not have access to certain functionalities, such as creating web maps and web scenes, the GIS administrator should configure the ArcGIS Enterprise home page to display only the items and tools that are accessible to the signed-in user. This customization ensures that users see a tailored interface that aligns with their permissions and responsibilities, reducing the likelihood of encountering inaccessible options.

Configuring a maintenance notification (Option A) is more appropriate for temporary service outages or updates, not for managing user interface elements. Adjusting Page visibility settings (Option B) affects the visibility of entire pages but does not provide the granular control needed to tailor the home page based on user roles and permissions.
