Sinceport 3306(MySQL) is open on the local workstation as confirmed by the Nmap scan, the next logical step is to checknetwork 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.
