Scapy can read packets from which type of file?

• A. A JSON log
• B. A pcap-style packet capture file
• C. A plain text log
• D. A database file

Answer: (B)

Scapy is designed to work with network packets, including reading pre-recorded traffic from capture files. A PCAP-style packet capture file stores the raw packets captured from a network, typically created by tools like tcpdump or libpcap. Scapy can load these captures (using functions like rdpcap), letting you inspect headers, decode protocols, and analyze payloads offline. The other options—JSON logs, plain text logs, or database files—aren’t stored as standard packet captures in a format Scapy uses for packet reconstruction, so they aren’t read as packet captures. So the file type Scapy reads to obtain packets is a pcap-style packet capture file.
