While troubleshooting a VPN issue between your gateway and a partner site you see an
entry in Smartview Tracker that states “Info: encryption failure: Different community ID:
possible NAT problem”. Which of the following is the most likely cause?
A.
You have an encryption method mismatch.
B.
Implied rules in global properties such as ICMP and DNS are set to first instead of before
last.
C.
You have not created a specific rule allowing VPN traffic.
D.
You have the wrong encryption domains configured.

I would also say D because the question mentions a “partner site” (3rd party) and not a gateway in your MGMT
