VMware NSX 4.x Professional (2023) — Question 81

In which VPN type are the Virtual Tunnel interfaces (VTI) used?

Answer options

• A. Policy & Route based VPNs
• B. Route & SSL based VPNs
• C. SSL-based VPN
• D. Route-based VPN

Correct answer: D

Explanation

Route-based VPNs use Virtual Tunnel Interfaces (VTI) to create a virtual point-to-point connection, enabling dynamic routing protocols to work. The other options either refer to policy-based VPNs, which do not use VTIs, or SSL-based VPNs, which operate differently and do not utilize VTIs.
