Episode 56: Protocols for File Transfer — FTP, SFTP, TFTP, and More
This episode introduces the protocols commonly used for transferring files across networks. File Transfer Protocol (FTP) is explained as a traditional method operating over TCP, often requiring additional security measures. Secure FTP (SFTP) provides encrypted transfers using SSH, while Trivial File Transfer Protocol (TFTP) offers a lightweight, UDP-based option often used in device bootstrapping and configuration transfers. These protocols are tested on the exam because they highlight differences in reliability, security, and use cases.
Practical applications include administrators using SFTP for secure updates, TFTP for deploying switch configurations, or FTP for legacy applications. Troubleshooting considerations are also addressed, such as blocked ports in firewalls or permissions errors that prevent file access. By mastering these distinctions, you’ll be able to identify the correct protocol in exam questions and select the appropriate tool in real-world file transfer scenarios.
