100-150 Question 218
Select 3A network administrator is troubleshooting intermittent connectivity issues reported by users in a branch office. They decide to use a packet analyzer to capture traffic. After capturing the data, they save it as a .pcap file for further analysis. What are the benefits of using a packet analyzer and saving the capture as a .pcap file?
- A
A .pcap file can be reopened later to analyze the traffic without needing to recapture it.
- B
Packet analyzers can help identify specific protocols or devices causing network issues.
- C
Saving as a .pcap file compresses the traffic data to save storage space.
- D
A .pcap file allows sharing the captured data with other tools or team members for collaborative troubleshooting.
- E
Packet analyzers can automatically resolve all network issues without requiring manual intervention.
Show answer and explanation
Correct answers: A, B, D
Explanation
Packet analyzers are critical for diagnosing network issues by capturing and analyzing traffic. Saving the captured data as a .pcap file ensures the data can be revisited, shared, and analyzed using various tools. However, packet analyzers are only diagnostic tools and do not resolve issues automatically or compress data when saved.
- A. Correct.
Correct: A .pcap file can be saved and reopened later, which is useful for analyzing traffic at a convenient time or sharing the data with others.
- B. Correct.
Correct: Packet analyzers can help identify specific protocols, devices, or unusual patterns causing network problems.
- C. Incorrect.
Incorrect: Saving as a .pcap file does not inherently compress the data. The file format preserves the raw packet data for accuracy.
- D. Correct.
Correct: A .pcap file can be shared with other tools or team members, allowing for collaborative troubleshooting or deeper analysis with specialized tools.
- E. Incorrect.
Incorrect: Packet analyzers are diagnostic tools and cannot resolve issues automatically. They require manual interpretation of the data to identify and fix problems.
