To minimize development effort, what action should you take first when creating a bookmark that hides three cards and shows a clustered bar chart?

To minimize development effort when creating a bookmark that hides three cards and shows a clustered bar chart, the most efficient initial action is to hide the three cards in the Selection Pane. This is because the Selection Pane allows you to manage the visibility of various elements on your report canvas. By hiding the unwanted cards beforehand, you set the stage for the bookmark to capture the current state of your report as intended.

Once the cards are hidden, you can then proceed to add a bookmark in the Bookmarks Pane which includes this newly configured view. This workflow helps to ensure that you have the exact configuration that you want the bookmark to represent, thereby reducing any extra steps that might be needed later to edit or adjust the bookmark.

The other options would not contribute as directly to minimizing effort. Adding a bookmark in the Bookmarks Pane could only be useful after you’ve made the necessary visibility adjustments. Publishing the report to the Power BI Service is a later stage action that doesn’t affect the current task of bookmark creation. The Spotlight option, while helpful for focusing on a specific visual, does not address the requirement of hiding other visuals and would add additional steps to the process rather than streamline it.
