Secure Command-Line File Transfer Protocols
A vendor needs to remotely and securely transfer files from one server to another using the command line. Which of the following protocols should be implemented to allow for this type of access? (Choose two.)
Community Insight
Tests knowledge of secure transport protocols by distinguishing between management interfaces (RDP) and secure shell/file transfer tools (SSH/SFTP), while filtering out insecure or unrelated options like SNMP and SMTP.
Identifies the correct protocols for secure, command-line-based remote file transfers between servers. Establishes that SSH and SFTP are the standard solutions for this requirement.
Candidates often select RDP because it provides remote access, but RDP is a graphical interface protocol, not suitable for command-line file transfers, and lacks the specific encryption guarantees required for secure data transit in this context.

Expert Analysis
Why the Answer Is Correct
The question requires two protocols that facilitate remote and secure file transfers via the command line. SSH (Secure Shell) is the foundational protocol that provides encrypted remote command-line access. SFTP (Secure File Transfer Protocol) operates over an SSH connection, providing a secure method for transferring files. Together, they form the standard solution for secure CLI-based file operations.Why the Other Options Are Wrong
RDP (Remote Desktop Protocol) is primarily used for graphical remote desktop sessions, not command-line file transfers. SNMP (Simple Network Management Protocol) is used for network monitoring and management, not file transfer, and often lacks encryption by default. S/MIME and SMTP are email-related protocols; SMTP handles mail transmission without inherent encryption for file payloads, and S/MIME secures email content, neither of which addresses direct server-to-server file transfer requirements.Community Comment Notes
Community feedback strongly supports the combination of SSH and SFTP. Users highlight that SSH ensures data privacy through encryption and that SFTP is built on top of SSH to provide secure file management capabilities. Comments explicitly note that these two protocols work together to meet the security and command-line constraints of the scenario.Exam Strategy
When asked about secure command-line access or file transfer, immediately look for SSH and its derivatives (like SCP or SFTP). Eliminate graphical protocols (RDP/VNC) and management protocols (SNMP) as they do not fit the 'file transfer' or 'command-line' criteria respectively.
Frequently Asked Questions
Why is RDP incorrect for file transfer?
RDP is designed for graphical remote desktop sessions, not for command-line file transfers. It does not natively support the secure, scriptable file transfer mechanisms required here.
Is SFTP a separate protocol from SSH?
SFTP runs over the SSH protocol. It uses the same encryption and authentication mechanisms as SSH but adds commands specifically for file manipulation and transfer.
