You create Microsoft Windows-based applications. You design a Windows Forms application that routes incidents to the most appropriate technical support representative. The application displays information in a Multiple Document Interface (MDI). A standard menu exists at the top of the MDI parent form. Toolbar containers provide functionality to the child forms. Users of the application are connected to the network locally and remotely. Five of the remote users have either visual or auditory impairments. Currently, a default beep alerts the users when a new support incident is assigned to them. You review the design and discover that the application fails to provide adequate
accessibility functionality. You need to provide an application status feedback technique that is appropriate for all users. What should you do?
A.
Update the status bar text in the main Window to indicate that a new incident is assigned to the user.
B.
Toggle the CAPS lock so that an LED on the users keyboard flashes to indicate that a new incident is assigned to the user.
C.
Display a Microsoft Outlook style pop-up message from the system tray to indicate that a new incident is assigned to the user.
D.
Play a configurable sound to indicate that a new incident is assigned to the user.
