Which of the following problems can be solved by using Wireshark?

Tracking source code version changes is the function of version control systems such as Git or SVN, not a network packet analyzer.

Checking webpage creation dates on a server requires server-side access or a web crawling utility, not packet capture analysis.

Resetting administrator passwords across multiple systems requires remote administration tools or directory services management consoles, not a packet sniffer.

Wireshark captures raw network packets and displays protocol-level details such as TCP RST flags, handshake failures, and retransmissions, allowing a technician to pinpoint exactly why communication between two systems is being reset. By filtering on specific IP addresses or ports, the analyst can isolate the exact exchange where the connection breaks down.
