Explanation
Ann started the FTP service on her PC, but the Windows (or host-based) firewall is blocking incoming FTP connections on port 21 by default. When a new service is started, the local firewall does not automatically permit traffic to it - a firewall exception (inbound rule) must be manually created to allow FTP traffic through. A static DNS entry would only help with name resolution, not connectivity. A dynamic IP address would make the PC harder to reach reliably. Management VLAN placement is a switch-side concern, not the reason FTP from the switch to the PC fails.
