Which SMTP extension does Cisco ESA support for email security?

Answer options

• A. ETRN
• B. UTF8SMTP
• C. PIPELINING
• D. STARTTLS

Correct answer: D

STARTTLS is the correct answer as it allows for the encryption of email transmissions, enhancing security. The other options, while they are valid SMTP extensions, do not specifically address email security in the same way that STARTTLS does.
