Q1Domain Verified
In the context of the "The Complete Secure FTP & SFTP Course 2026," which underlying cryptographic protocol is fundamental to establishing a secure SFTP connection, and what is its primary function in this context?
TLS (Transport Layer Security) for encrypting data in transit and authenticating servers.
IPsec (Internet Protocol Security) for encrypting IP packets at the network layer and providing authentication.
SSH (Secure Shell) for secure remote login, command execution, and importantly, file transfer.
SSL (Secure Sockets Layer) for establishing secure communication channels and ensuring data integrity.

According to "The Complete Secure FTP & SFTP Course 2026," what is the key architectural difference between FTPS and SFTP that dictates their respective port usage and firewall configuration requirements?
FTPS is designed for encrypted data transfer only, using port 990. SFTP is designed for secure command execution and file transfer, utilizing port 22 for both.
FTPS relies on implicit TLS, securing all traffic on port 990. SFTP, however, uses explicit TLS on port 21 for initial handshake and then a separate data channel.
FTPS operates with separate control and data connections, both encrypted, requiring multiple ports (21 for control, dynamic for data). SFTP, conversely, multiplexes data and commands over a single, secured SSH connection on port 22.
FTPS uses a single control connection and a single data connection, both secured by TLS/SSL, typically on ports 21 and 990. SFTP, being a subsystem of SSH, uses a single connection on port 22.

probes a critical practical aspect. FTPS (FTP over SSL/TLS) has two distinct connection types: a control connection (typically port 21) and a data connection (which can be dynamically assigned or use a passive port). Both are secured by TLS/SSL. SFTP, on the other hand, is a subsystem of SSH and operates entirely over a single SSH connection, multiplexing both commands and dat
This single-connection nature of SFTP, secured by SSH on its standard port 22, simplifies firewall configurations compared to the multi-port nature of FTPS. Option A incorrectly states FTPS uses a single data connection and SFTP uses multiple ports. Option C misrepresents the TLS modes for FTPS and SFTP. Option D incorrectly limits FTPS to data transfer only. Question: Within the "The Complete Secure FTP & SFTP Course 2026," when discussing public key authentication for SFTP, what is the fundamental role of the private key held by the client and the corresponding public key stored on the server? A) The client's private key is used to decrypt data sent by the server, and the public key on the server verifies the client's identity.
The client's private key is shared with the server to establish a symmetric encryption key for the entire session, while the public key is used for initial server authentication.
The client's private key is used to sign a challenge from the server, and the server uses the corresponding public key to verify this signature, thereby authenticating the client without a password.
The server's private key is used to encrypt the initial connection, and the client's public key is used to decrypt this encrypted handshake.
