Explanation

Running tcpdump without appropriate filtering or with verbose options can lead to excessive CPU usage and impact the performance of the firewall. It is essential to use specific switches and filters to limit the scope of the capture to necessary traffic only, thereby minimizing the performance overhead. Contrary to Option A, tcpdump can capture various types of packets, including TCP and UDP. Option B is incorrect as tcpdump is run from the command line, not initiated directly from SmartConsole. Option C is partially true but not as directly relevant as the impact on performance.
