100-150 Question 215
Select 3A network technician is troubleshooting intermittent connectivity issues on a company network. To analyze network traffic, the technician uses a packet analyzer to capture data and saves it as a .pcap file. Later, they reopen the .pcap file for further analysis. What are the primary purposes of saving and reopening a .pcap file in this scenario?
- A
To allow detailed offline analysis of network traffic at a later time.
- B
To share captured network traffic data with other technicians or teams for collaborative troubleshooting.
- C
To automatically fix network issues identified in the packet capture.
- D
To use the saved .pcap file as evidence for documenting and reporting network problems.
- E
To run automated scripts directly on the .pcap file to modify captured packets.
Show answer and explanation
Correct answers: A, B, D
Explanation
Saving and reopening a .pcap file is essential for detailed offline analysis, collaboration with other team members, and documentation of network issues. It allows technicians to revisit captured traffic without requiring real-time monitoring, making it a fundamental feature of packet analyzers. However, packet analyzers are diagnostic tools and do not automatically resolve or modify traffic issues.
- A. Correct.
Correct. Saving a .pcap file allows the technician to analyze the captured traffic offline at a more convenient time without needing to recapture live traffic.
- B. Correct.
Correct. Sharing .pcap files enables other technicians or teams to review the captured traffic and assist in troubleshooting.
- C. Incorrect.
Incorrect. Packet analyzers only capture and analyze traffic; they do not automatically resolve network issues.
- D. Correct.
Correct. Saved .pcap files can be used as evidence to document network problems for reporting purposes or for audits.
- E. Incorrect.
Incorrect. Automated scripts are not typically run directly on .pcap files to modify captured packets. Modifications, if needed, are usually performed in specialized tools.
