CompTIA Server+ (SK0-005)Server AdministrationEasy
A server administrator needs to remotely manage a Linux server over a secure, encrypted connection. The management tasks include executing commands, transferring files, and managing user accounts. Which protocol should the administrator use?
- AHTTP
- BSSH
- CFTP
- DTelnet
Show answer & explanationAnswer & explanation
Correct answer: B. SSH
SSH (Secure Shell) provides a secure, encrypted channel for remote command-line access, file transfers (via SCP/SFTP), and other network services, making it the standard for Linux server management.
Why the other options are wrong
- A. HTTP is for web traffic and does not provide remote server management capabilities.
- C. FTP (File Transfer Protocol) is primarily for file transfers and is unencrypted by default, not for command execution.
- D. Telnet is an unencrypted protocol and is insecure for remote management.
SSH (Secure Shell)
A cryptographic network protocol for operating network services securely over an unsecured network.
- Provides secure remote shell access.
- Encrypts all communication.
- Used for command execution, file transfer (SCP/SFTP), and tunneling.
Memory trick: SSH is the secure key to remote server doors.
