What capability does the 'Display Filters' dialog provide?

• A. View existing filters
• B. Apply as a new conversation filter
• C. Create and save named display filters for reuse
• D. Delete a saved filter

Answer: (C)

Display filters are the expressions you use to decide which packets Wireshark shows. The Display Filters dialog is where you create and manage those filters by name. The key capability is to create a filter expression, give it a descriptive name, and save it so you can reuse it later without retyping the whole expression. Once saved, you can quickly apply it from the list or toolbar, enabling consistent, efficient filtering across sessions. You might also edit or delete saved filters, but the main idea is building a library of named display filters for easy reuse.
