What is the purpose of inspecting the payload of packets in a PCAP file during intrusion analysis?

To identify the transport-layer protocol used.

To determine the source and destination IP addresses of the packet.

To calculate the checksum of the packet.

To identify application-layer data, such as commands, files, or malicious content.

What is the basic structure of a PCAP file?

A single header followed by raw packet data with no per-packet metadata.

A series of independent files, each containing one packet and its metadata.

A global header followed by a series of packet records, each with its own header and captured data.

A global header, then a single large block containing all packet data concatenated together.
