How are fine-grained options specified in Scapy's send functions?

• A. As variable=value pairs inside the function call
• B. In a separate config file
• C. As command-line arguments
• D. They cannot be specified

Answer: (D)

In Scapy, fine-grained control for sending is provided by passing keyword arguments directly to the send functions. This means you specify named options inside the function call to tune how the packet(s) are sent, without touching config files or the command line. Each option adjusts a specific aspect of the sending process, such as how many packets to send (count), the delay between sends (inter), which network interface to use (iface), and how long to wait for responses (timeout), among others. For example: send(IP(dst='10.0.0.1')/ICMP(), count=5, inter=0.2, iface='eth0', timeout=2, verbose=0). This approach makes the behavior explicit for that particular invocation and is the standard way to configure per-send behavior in Scapy.
