What does MO-210's Manage Charts domain cover?

Two skills: creating a chart (Insert > Charts, or Alt+F1 for an instant default chart on the current sheet), and creating a chart sheet specifically — a dedicated sheet that contains nothing but the chart, reached via the Move Chart dialog or F11 for an instant chart sheet.

The distinction matters for a task that specifically says "chart sheet": an embedded chart sitting on a worksheet is not the same object as a chart sheet, and a check looking for the latter will not accept the former.

This group covers adding a data series to an existing chart, switching between rows and columns as the source data's series (the Switch Row/Column button on Chart Design), and adding or modifying chart elements — titles, axis labels, gridlines, data labels, legends, and trendlines via the Chart Elements (+) button.

Switching rows and columns is the one candidates most often skip, because it is a single button rather than a menu of options, and it is easy to overlook when a task's real ask is simply "the series should be organized differently" without naming the button.

Applying chart layouts and chart styles (the Quick Layout and preset style galleries on Chart Design) covers the visual side. The third skill — adding alternative text to charts for accessibility — is easy to forget because it lives under Format Chart Area > Alt Text rather than anywhere on the main ribbon tabs, and it is explicitly named as its own objective, not an optional extra.

If a task asks you to make a chart accessible or add a description, alt text is specifically what is being checked, not a title or a caption in a nearby cell.
