What action should be taken to ensure that new maps opened by users of your organization focus on the city boundaries?

Choosing to define the default extent is the most effective action to ensure that new maps opened by users in your organization focus on the city boundaries. The default extent determines the initial geographic area that users will see when they open a map. By setting the default extent to align with the city boundaries, any map will automatically zoom in on the relevant urban area, guiding users to the specific location you want them to explore.

This approach is particularly useful in enhancing user experience, as it minimizes the need for users to manually navigate to the desired area. It allows for immediate access to pertinent data and resources related to the city, thereby improving efficiency in map usage.

Setting the primary map viewer, while important for overall user experience, does not directly control the initial geographic view in the same way. Similarly, defining analysis layers pertains more to the content displayed on the map rather than the specific geographic focus. Lastly, the default basemap relates to the visual appearance of the map rather than setting the geographic starting point. Thus, focusing on the map's default extent is essential for directing users' attention to the intended area right from the start.
