Refer to the Exhibit.

Server A is communicating with Server B directly over the Internet. The servers now must begin
exchanging additional information through an unencrypted protocol. To protect this new data
exchange, you want to establish a VPN tunnel between the two sites that will encrypt just the
unencrypted data while leaving the existing communications directly over the Internet.
Which statement would achieve the desired results?

A.
Configure a route-based VPN and use filter-based forwarding to direct traffic into the VPN
tunnel.

B.
Configure a route-based VPN tunnel with traffic engineering to direct traffic into the VPN tunnel.

C.
Configure a policy-based VPN with a security policy that matches the unencrypted traffic and
directs it into the VPN tunnel.

D.
Configure a policy-based VPN tunnel and use filter-based forwarding to direct the unencrypted
traffic into interface st0.0.
