A. B. C. D. E. F.AF.
The two ports used for secure sessions are:
F. 443 - This port is used for HTTPS (Hypertext Transfer Protocol Secure), which is a secure version of HTTP. HTTPS uses encryption to protect data transmitted between a client and a server, ensuring that any data exchanged between the two is secure and cannot be intercepted by third parties.
A. 22 - This port is used for SSH (Secure Shell), a secure protocol for remote access to a computer or network. SSH provides a secure channel over an unsecured network, enabling secure communication between the client and server.
The other options are:
B. 23 - This port is used for Telnet, a protocol used for remote access to a computer or network. However, Telnet is an unsecured protocol, meaning that data transmitted between the client and server is not encrypted and can be intercepted by third parties.
C. 25 - This port is used for SMTP (Simple Mail Transfer Protocol), which is used to send email messages between servers. SMTP is not a secure protocol, and email messages sent using SMTP can be intercepted and read by third parties.
D. 80 - This port is used for HTTP (Hypertext Transfer Protocol), which is used to transfer data between a client and server. However, HTTP is not a secure protocol, meaning that data transmitted between the client and server is not encrypted and can be intercepted by third parties.
E. 110 - This port is used for POP3 (Post Office Protocol version 3), which is used to retrieve email messages from a server. However, like SMTP, POP3 is not a secure protocol, and email messages retrieved using POP3 can be intercepted and read by third parties.
In summary, ports 22 (SSH) and 443 (HTTPS) are used for secure sessions, while the other options are not secure and should be used with caution.
