Which two descriptions correctly identify an IPsec VTI VPN? (Choose two.)
- allows multicast and broadcast traffic over a secure site-to-site VPN
- has both Layer 2 and Layer 3 implementations
- involves a nonsecure tunneling protocol being encapsulated by IPsec
- routes packets through virtual tunnel interfaces for encryption and forwarding
- uses the public key infrastructure and digital certificates
Explanation: An IPsec VTI VPN routes packets through virtual tunnel interfaces for encryption and forwarding. An IPsec VTI VPN and a GRE over IPsec VPN allow multicast and broadcast traffic over a secure site-to-site VPN. An MPLS VPN has both Layer 2 and Layer 3 implementations. A GRE over IPsec VPN involves a nonsecure tunneling protocol being encapsulated by IPsec. An SSL VPN uses the public key infrastructure and digital certificates.
