An Enterprise Company Has an Audit Requirement to Encrypt Traffic

Multiple Choice

An enterprise company has an audit requirement to encrypt traffic between selected development teams. Those teams are located in multiple sites across the country. They must migrate all locations to an MPLS Layer 3 VPN-based service, but this implementation must not impact the VoIP solution. The VoIP traffic to and from the call center sites must be copied to the data center servers so that it is recorded to meet another audit requirement. Which solution meets these requirements?

A) Implement GETVPN with selective encryption only for the development traffic
B) Implement a DMVPN-based solution encrypting all traffic except the VoIP traffic
C) Implement LISP-based tunnels for the development traffic
D) Implement site-to-site GRE tunnels only for development traffic
