Which other utility can read and analyze a packet trace file generated by the storage system?

• A. Eternal View
• B. Netmon
• C. pktt
• D. WireShark

Answer: (D)

Packet trace files from a storage system are usually saved in a standard capture format (pcap/pcapng), which records every packet seen on the network. To study what happened in that trace, you need a tool that can read that format and decode the protocols involved. Wireshark is the go-to because it opens PCAP files directly and provides detailed protocol dissections for each packet. It shows you exactly what’s inside, how the frames are built, and how the communication unfolds across layers, which is essential for diagnosing latency, errors, or misconfigurations in storage traffic (like iSCSI, FC, TCP, etc.). You can apply filters to focus on specific hosts, ports, or protocol conversations, reassemble streams to see complete transactions, and use statistics and graphs to spot patterns. Other options in the list aren’t as universally capable of reading and deeply analyzing PCAP traces, so Wireshark is the most reliable and informative choice for this task.
