Show answer and explanation
Correct answers: A, B, D, E
Explanation
To capture packets with Wireshark, you must ensure the correct interface is selected and then start the capture process to collect data. After gathering the necessary information, stop the capture to finalize it. You can then save the captured packets using options like 'Export Specified Packets' for future analysis. Using the 'Save As' option during an active capture is not a recommended practice as it may result in incomplete or corrupted files.
- A. Correct.
Correct. Selecting the correct network interface ensures that you capture traffic from the desired source.
- B. Correct.
Correct. The 'Start Capture' button begins the packet capture process, allowing you to collect network data.
- C. Incorrect.
Incorrect. It is not recommended to use 'Save As' during an active capture as it might disrupt the process or result in incomplete saves. Captures are typically saved after stopping.
- D. Correct.
Correct. Stopping the capture is necessary to finalize the data collection and ensure no additional packets are captured.
- E. Correct.
Correct. The 'Export Specified Packets' option allows saving the captured data to a file for later analysis.
