Question

12/27
port number 587 is for which traffic?
video traffic
websites
email
file transfer

Explanation:

Port number 587 is associated with SMTP (Simple Mail Transfer Protocol) submission, which is used for email traffic. Video traffic uses different ports (e.g., for streaming protocols), websites typically use ports 80 (HTTP) or 443 (HTTPS), and file transfer uses ports like 21 (FTP) or 22 (SFTP). So port 587 is for email traffic.

Answer:

email
