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