What are two application layer preprocessors? (Choose two.)

Answer options

• A. CIFS
• B. IMAP
• C. SSL
• D. DNP3
• E. ICMP

Correct answer: B, C

Explanation

IMAP and SSL are both considered application layer protocols. IMAP is a protocol used for retrieving emails, while SSL provides a secure communication channel over the internet. The other options, such as CIFS, DNP3, and ICMP, serve different functions and do not primarily operate at the application layer.
