ISC2 Certified in Cybersecurity (CC) Practice Question
When an employee uses a VPN client from a public Wi-Fi hotspot, what primary security benefit does the VPN provide during data transmission across the internet?
It encrypts the traffic, preventing eavesdroppers on the hotspot from reading the data.
It increases available bandwidth by routing through multiple parallel paths.
It blocks malware by inspecting every downloaded file in real time.
It assigns a new MAC address to the client, stopping all tracking.
A Virtual Private Network (VPN) establishes an encrypted tunnel between the user and the trusted network. This encryption renders the packets unreadable to anyone who might intercept them on the public Wi-Fi or elsewhere on the internet, thereby preserving confidentiality and integrity. Changing the device's MAC address, performing full malware inspection, or increasing bandwidth are not core functions of a VPN, though some related products may add such features separately.
