The current release of Check Point R77, what is a potential performance-related drawback to using Virtual Tunnel Interfaces (VTI) rather than Domain-based
VPNs?

A. Use of VTIs will disable CoreXL and therefore will negatively impact hardware platforms running more than one CPU core.
B. Dynamic routing protocols will work across a domain-based VPN, but will not work across a VTI.
C. Use of VTIs will disable the entire SecureXL mechanism and prevent any traffic acceleration.
D. Domain-based VPNs are easier to configure than VTIs and therefore is the preferred implementation.
