If you modify the symbology of existing layers before sharing a new web map, what happens to the original layers?

• A. The original layers are automatically updated
• B. The original layers retain their characteristics
• C. The original layers are deleted
• D. The original layers become hidden

Answer: (B)

When you modify the symbology of existing layers before sharing a new web map, the original layers retain their characteristics. This is because changes made to a web map's symbology do not alter the underlying data of the original layers. Instead, they create a new representation of that data specific to the web map for visualization purposes. The original layers maintain their original settings, attributes, and symbology as stored in their source. Therefore, any changes applied to the symbology within the web map are not reflected back to the original layers stored in the ArcGIS platform. This separation allows users to create customized visualizations without impacting the core data or properties of the layers in other contexts or applications. This functionality is important for maintaining data integrity and allows for multiple visual interpretations of the same underlying data set for different use cases or audiences.
