correct answer is D All packets that cannot be matched to programmed flows are dropped by default. You can configure sending unmatched packets to the controller. You can modify the default action taken on unmatched packets either using the default-miss command or by the controller. https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst2960x/software/15-2_5_e/configuration_guide/b_1525e_consolidated_2960x_cg/b_1525e_consolidated_2960x_cg_chapter_01001101.html
