Question

When should an ArcGIS user change the reference scale of an existing map annotation?

A. when the user adds a scale bar to the map layout
B. when the user brings data into the map that has a projected coordinate system
C. when the user creates a new feature linked annotation feature class and adds it to a new data frame for editing D. when the user uses the same map template to create a second map that contains data from a different geographic area

Answer 1

An ArcGIS user should change the reference scale of an existing map annotation when creating a new feature linked annotation feature class and adding it to a new data frame for editing.

Step-by-step explanation:

An ArcGIS user should change the reference scale of an existing map annotation when the user creates a new feature linked annotation feature class and adds it to a new data frame for editing (Option C). Changing the reference scale in this case allows the user to maintain the correct size and placement of the annotation at different map scales. By changing the reference scale, the annotation can dynamically adjust its size and position based on the scale at which the map is being viewed. This ensures that the annotation remains readable and meaningful to the map viewers at different scales.
