When conducting a penetration test, it is crucial to use all means to get all available information about the target network. One of the ways to do that is by sniffing the network. Which of the…
The correct answer is B. Modifying and replaying captured network traffic. Passive network sniffing observes traffic without interacting with it, making it incapable of actively altering or replaying data.

Why each option
Passive network sniffing observes traffic without interacting with it, making it incapable of actively altering or replaying data.
Passive sniffing can effectively identify operating systems, services, protocols, and devices by observing the characteristics and patterns of the traffic they generate.
Passive network sniffing is limited to capturing and analyzing existing network traffic; it lacks the capability to modify packets or replay captured data, as these actions require active interaction with the network.
A passive sniffer can readily collect unencrypted information, such as cleartext usernames and passwords, directly from the captured network traffic.
Capturing network traffic for subsequent analysis is a fundamental and primary function of passive network sniffing tools.
