A sniffer is a tool that captures and analyzes network traffic on a subnet or a network interface. It can help identify the source, destination, protocol, and content of the traffic and detect any anomalies or issues on the network. Verified References: [Sniffer], [Network traffic]

Since port 3306 (MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to check network firewall rules. It’s possible that the workstation’s firewall or network-level security rules are blocking outbound or inbound traffic on port 3306, which is required for database access.

Edit the network firewall rules (Answer D): Ensuring the firewall allows traffic on port 3306 is the appropriate next step, especially since other workstations are not having the same issue.

Checking the database server (Option A): This is unnecessary because other workstations can access the server, confirming the server itself is functioning correctly.

Changing the database password (Option B): This would not resolve the issue of one workstation being unable to connect while others can.

Opening port 3306 on the server (Option C): The problem isn't server-side since other machines can connect without issue.

The concept in use when dual power supplies are connected to different power sources is fault tolerance. Fault tolerance is the ability of a system to continue operating without interruption or loss of data in the event of a failure of one or more components. By connecting dual power supplies to different power sources, the system can switch to the alternative power supply or source if one fails, ensuring continuous availability and reliability.
