Explanation
When port forwarding is unavailable and network configuration cannot be changed, VNC (Virtual Network Computing) is the best fit because it supports a 'reverse connection' mode-the remote machine initiates an outbound connection to the technician's viewer rather than waiting for an inbound connection. This bypasses the need for any open or forwarded ports on the remote router. In contrast, RDP (port 3389), SSH (port 22), and Telnet (port 23) all require inbound ports to be accessible. Third-party tools like TeamViewer also work without port forwarding, but the exam identifies VNC as the target answer here due to its built-in reverse-connection capability.
