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?
Correct Answer: B
Explanation
Port 25 is the port number that is commonly used for Simple Mail Transfer Protocol (SMTP), which is a protocol that allows sending and receiving email messages over a network1. Port 25 from the copier's IP address should be allowed so that scanned documents can be emailed to recipients.
Port 22 is the port number that is commonly used for Secure Shell (SSH), which is a protocol that allows secure and encrypted remote access and control of a device over a network1. Port 22 from the copier's IP address is not necessary for emailing scanned documents.
Port 53 is the port number that is commonly used for Domain Name System (DNS), which is a protocol that allows resolving domain names to IP addresses and vice versa on a network1. Port 53 from the copier's IP address is not necessary for emailing scanned documents.
Port 80 is the port number that is commonly used for Hypertext Transfer Protocol (HTTP), which is a protocol that allows transferring web pages and other resources over a network1. Port 80 from the copier's IP address is not necessary for emailing scanned documents.
