Which of the following transport protocols are supported by scheduled NIOS Grid Backup? (Select all that apply.)
Correct Answer: A,B,C,D
Comprehensive and Detailed In-Depth Explanation:NIOS Grid Backup allows scheduled exports of the configuration database (DNS, DHCP, Grid settings) to an external server. Supported protocols ensure flexibility and security:
* A (SFTP):Secure File Transfer Protocol (SSH-based) is supported for encrypted backups to remote servers (port 22). Widely used for secure transfers. Correct.
* B (SCP):Secure Copy Protocol (also SSH-based) is supported, offering a simple, secure file transfer option (port 22). Correct.
* C (FTP):File Transfer Protocol (unencrypted, port 21) is supported for legacy systems, though less secure. Correct.
* D (HTTPS):Web-based secure transfer (port 443) is supported, allowing backups to HTTP servers with SSL/TLS encryption. Correct.
* Setup:In Grid Manager (Grid > Grid Manager > Backup), you configure the protocol, server IP, and credentials.
* Practical Example:In an INE lab, you'd schedule a backup using SFTP to a remote server, test restoration, and troubleshoot connectivity issues, reinforcing Grid deployment skills.
* Note:All four are explicitly supported per NIOS documentation, making this a comprehensive list.
