Which of the following is NOT a function of Wireshark?

Network troubleshooting
Password cracking
Packet analysis
Communications protocol development

The correct answer is: Password cracking

Wireshark is a powerful tool primarily utilized for network protocol analysis, capturing packets, and providing insights into network traffic. It serves numerous important functions that are essential for network administrators, cybersecurity professionals, and developers. Network troubleshooting is one of the core functions of Wireshark, as it allows users to analyze packet data to identify network issues, monitor performance, and diagnose problems. Packet analysis is another key capability, enabling users to inspect individual packets in detail to understand the flow of data across the network. Moreover, Wireshark is valuable in communications protocol development because it lets developers view the actual data being sent over the network, providing a clear picture of how protocols perform and allowing for debugging and improvements. In contrast, password cracking is not a function of Wireshark. While the tool can capture packets that may include password transmissions, it does not have built-in functionality for cracking passwords. Password cracking typically involves other specialized tools focused specifically on breaking encryption or hashes, which is outside the scope and purpose of Wireshark. Thus, identifying Wireshark's non-function aligns with understanding its capabilities and limitations.
