Which toolbar allows you to type filter expressions on the fly to filter packets?

• A. Filter Toolbar
• B. Status Bar
• C. Packet Details Pane
• D. Main Toolbar

Answer: (D)

The main idea here is using the toolbar that provides the display filter input to refine what you see in real time. In this UI, you type your filter expressions into the display filter box that sits in the main toolbar, so as you enter or adjust the expression the packet list updates immediately. That on-the-fly filtering is exactly what you want when you need to quickly narrow down packets without leaving the main window. The status bar just shows status information, and the packet details pane shows details for a selected packet rather than filtering the list, so they don’t serve the same purpose. A dedicated Filter Toolbar could exist in other layouts, but in this setup the quick access to typing and applying filters is part of the main toolbar, making it the right place for immediate, on-the-fly filtering.
