Refer to the exhibit. With this in-room configuration, which command successfully sets the slider to 50?

Question

Exhibit

Options

• Axcommand UserInterface Extensions Widget SetSlider Value: 50
• Bxcommand UserInterface Extensions Widget Slider: 50 Widget: "widget_1"
• Cxconfiguration UserInterface Extensions widget_1 50
• Dxcommand UserInterface Extensions Widget SetValue WidgetId: "widget_1" Value: 50

• A
  81% (43)
• B
  2% (1)
• C
  8% (4)
• D
  9% (5)

Explanation

Option A uses the correct Cisco xAPI command structure: xcommand is the proper command type for triggering runtime UI actions, and SetSlider is the specific sub-command for slider widgets - no Widget ID is needed in this context because the exhibit shows a single-widget configuration where the slider is the active target.

Option B fails because the parameter syntax is invalid - Slider: 50 is not a recognized parameter, and the Widget ID should use WidgetId: not Widget:. Option C is wrong because xconfiguration is used for persistent device settings, not for dynamically controlling UI widget states at runtime. Option D looks plausible but uses SetValue, which is a generic widget command for text and toggle widgets - not the slider-specific SetSlider command tested here.

Memory tip: Think "match the widget, match the command" - sliders use SetSlider, and whenever you're doing something to a UI widget at runtime, it's always xcommand, never xconfiguration.
