Final answer:
A PC technician would recommend a VPN as a security solution for a manager traveling and needing secure access to internal corporate resources.
Step-by-step explanation:
For a manager traveling who needs secure access to internal corporate resources, a PC technician would recommend a VPN (Virtual Private Network) as the most suitable security solution. A VPN creates an encrypted connection over the internet from the device to the corporate network. This ensures that sensitive data is kept secure and private, as the encryption prevents unauthorized access, even when using public Wi-Fi networks. VPNs are widely used for remote work and are an essential tool for professionals who need to access their company's network resources from different locations.
