Which expression provides a brief summary of a Scapy packet?

• A. >>>packet
• B. >>>packet.summary()
• C. >>>packet.show()
• D. ls(packet)

Answer: (B)

In Scapy, the quickest, most compact way to describe a packet is by calling the summary() method. This returns a concise one-line string that shows the protocol layers and the key routing information, typically something like Ether / IP / TCP 10.0.0.5:12345 > 10.0.0.1:80. It’s designed for quick inspection, logging, or displaying a snapshot of the packet.

Printing the packet itself or using show() serves different purposes. The plain print (or typing the variable) tends to show the layered structure but can be longer and less standardized for quick reading. The show() method, on the other hand, dumps every field in a verbose, multi-line format—great for thorough debugging but not a brief summary. The ls(...) approach is for exploring available fields of protocol classes, not for producing a concise packet summary.
