Explanation

Virtual Private Network (VPN) connections are the correct choice because VPNs encrypt all data transmitted between the mobile device and the internet, creating a secure "tunnel" that protects sensitive information even when connecting to untrusted or unfamiliar networks - exactly the scenario RevoMedia faces during off-site client presentations.

Why the distractors are wrong:

• Bluetooth pairing (A) is designed for short-range device-to-device connections (e.g., headsets, keyboards) and is not a method for connecting to networks for internet access; it also carries its own vulnerabilities like bluejacking and bluesnarfing.
• USB tethering (C) shares a connection between physically connected devices and is limited in scope; it doesn't provide encryption or protection against network-based threats on unfamiliar networks.
• Direct Wi-Fi connectivity (D) is arguably the most dangerous option, as connecting directly to unknown Wi-Fi networks exposes devices to man-in-the-middle attacks, rogue hotspots, and data interception.

Memory Tip: Think of a VPN as a "private armored tunnel" through a dangerous public road - no matter how risky the road (unfamiliar network) is, your data travels safely inside the tunnel. Whenever you see "unfamiliar/public networks + security," VPN is almost always the answer.
