B is wrong
From manual admin:
"If you uncheck the SMTP over SSL/TLS option, STARTTLS will not be advertised to the client and the SMTPS port
(465) will not be listening. As a result, the FortiMail unit will not accept emails through TLS/SSL."
The connection only reverts to standard SMTP id SSL/TLS is enables for (FML2) and SMTPS also enabled for (FML1) . However for this case ssl/tls is unchecked therefore this means there will be no communication at all. Correct answer is D
It's A. From the NSE6 course: by default, if the backend server (FML2 in this case) doesn't support SMTPS (which it doesn't as SMTP over SSL/TLS is disabled), the connection reverts to standard SMTP
From the NSE6 Study Guide p298: by default, if the backend server (FML2 in this case) doesn't support SMTPS (which it doesn't as SMTP over SSL/TLS is disabled), the connection reverts to standard SMTP
