Which two operational advantages does Get VPN offer over site-to-site IPsec tunnel in a private MPLS-based core network? (Choose two.)
A. Packets carry original source and destination IP addresses, which allows (or optimal routing of encrypted traffic.
B. Group Domain of Interpretation protocol allows for homomorphic encryption, which allows group members to operate on messages without decrypting them.
C. NETVPN is tunnel-less, which allows any group member to perform decryption and routing around network failures.
D. Key servers perform encryption and decryption of all the data in the network, which allows for tight security policies
E. Traffic uses one VRF to encrypt data and a different one to decrypt data, which allows for multicast traffic isolation
