Your network contains an Active Directory domain named contoso.com. The domain contains an Application
server named Server1. Server1 runs Windows Server 2012.
Server1 is configured as an FTP server.
Client computers use an FTP Application named App1.exe. App1.exe uses TCP port 21 as the control port and
