CompTIA Network+ (N10-008) — Question 447

A newly installed multifunction copier needs to be set up so scanned documents can be emailed to recipients. Which of the following ports from the copier’s IP address should be allowed?

Answer options

• A. 22
• B. 25
• C. 53
• D. 80

Correct answer: B

Explanation

Port 25 is used for SMTP, the protocol responsible for sending emails, making it essential for the copier to email scanned documents. Port 22 is used for SSH, port 53 is for DNS queries, and port 80 is for HTTP traffic, none of which are relevant for email transmission.
