Explanation
Windows Firewall controls inbound and outbound network traffic based on rules. FTP uses TCP port 21, and Windows Firewall can have explicit rules that block specific ports, protocols, or addresses. The technician should inspect Windows Firewall's outbound rules to see if FTP (port 21) is blocked. BitLocker (A) is a drive encryption feature. BranchCache (B) is a WAN optimization feature for caching network content. User Account Control (C) manages application privilege elevation, not network port access.
