Which VPN type uses TLS to secure channels and is typically accessed via standard web browsers?

• A. IPsec VPN
• B. PPTP VPN
• C. TLS VPN
• D. SSL VPN

Answer: (C)

TLS-based VPNs secure the connection using the TLS protocol, the same security layer web browsers rely on for HTTPS. Because browsers already speak TLS, these VPNs can be accessed through a regular browser via a web portal without needing a separate VPN client, making them convenient for browser-based use. The other options rely on different mechanisms: IPsec VPNs typically require a dedicated VPN client and operate at the IP layer; PPTP is an older protocol with weaker security; SSL VPNs also use SSL/TLS for secure access and are browser-friendly, but the term TLS VPN specifically highlights the TLS-encrypted channel, matching the described access method.
