https://docs.microsoft.com/en-us/windows-server/remote/remote-access/ras/manage-remote-clients/install/step-1-configure-the-remote-access-infrastructureThe correct answer is D. 443.
Secure remote access usually implies using a secure protocol such as HTTPS, which encrypts data in transit between the client and server. HTTPS uses port 443 by default.
Port 21 is used for FTP (File Transfer Protocol) which is not a secure protocol as it sends data in plaintext. Port 22 is used for SSH (Secure Shell), but it is not commonly used for remote access to servers. Port 23 is used for Telnet, an unencrypted protocol which is insecure and should not be used for remote access to servers.
Therefore, the correct port for secure remote access in this scenario is port 443.
