Securing Email with Cisco Email Security Appliance (SESA) — Question 6

What must be configured to allow the Cisco ESA to encrypt an email using the Cisco Registered Envelope Service?

Answer options

• A. provisioned email encryption profile
• B. message encryption from a content filter that select "Message Encryption" over TLS
• C. message encryption from the mail flow policies with "CRES" selected
• D. content filter to forward the email to the Cisco Registered Envelope server

Correct answer: B

Explanation

The correct answer is B because it specifies that a content filter must be configured to use 'Message Encryption' over TLS, which is necessary for encrypting emails. Options A, C, and D do not directly relate to the required configuration for encrypting emails with the Cisco Registered Envelope Service.
