A user is requesting Telnet access to manage a remote development web server. Insecure protocols are not allowed for use within any environment. Which of the following should be configured to allow remote access to this server?

SSH (Secure Shell) is the correct choice because it provides a secure, encrypted channel for remote command-line access and management. This directly addresses the requirement for secure protocols and replaces the insecure Telnet. HTTPS is for secure web browsing, not remote server management. SNMPv3 is for network device monitoring and management, not general server access. RDP (Remote Desktop Protocol) is for graphical remote access to Windows servers, which isn't specified here and might not be suitable for a development web server where command-line access is often preferred. SMTP is for sending email.
