A designer at Brightleaf Retail wants a commentary container on a dashboard to appear only when viewers turn on a toggle, using dynamic zone visibility rather than a separate dashboard. Which TWO conditions must hold for dynamic zone visibility to control whether that container is shown or hidden? Select TWO.
- AThe controlling field driving the zone must be a Boolean, returning either true or false to decide whether the zone is displayed. Correct
- BThe controlling field must be a parameter or a calculated field present on the dashboard, so its value can be read at viewing time. Correct
- CThe container must be set to a tiled layout, because dynamic zone visibility refuses to hide any object that has been floated.
- DA navigation button must be wired to the zone first, since the button is what physically swaps the container in and out of view.
- EThe driving field must be a continuous measure aggregated to a single number, which the zone compares against a fixed threshold value.
Why A is correct: Dynamic zone visibility reads a true or false signal, so a Boolean field or parameter is required to flip the zone on or off.
Why B is correct: The driver has to be a parameter or a field used in the dashboard so its current value resolves while the viewer interacts.
Why C is wrong: This sounds like a layout rule, but dynamic zone visibility works on tiled and floating objects alike rather than tiled only.
Why D is wrong: A navigation button jumps between sheets, so it has no role in toggling a zone that dynamic zone visibility already governs.
Why E is wrong: A continuous measure seems usable, but the zone needs a true or false Boolean signal, not an aggregated numeric threshold.
