Which of the following protocols does pyATS support for connecting to a device?

pyATS (Python Automated Test Systems) is a Python-based framework developed by Cisco to facilitate automated testing and software validation for network devices. Among the protocols supported by pyATS for connecting to devices, Telnet is one of the primary options.

Telnet allows for remote control of devices over a network, and it establishes a virtual terminal session that can be used to access device command-line interfaces. pyATS leverages this capability to enable users to automate tasks such as configuration changes, device monitoring, and testing procedures through script-based interactions.

While other protocols mentioned can play roles in different contexts or applications, they are not directly associated with the connection mechanism provided by pyATS for device management. SNMP (Simple Network Management Protocol) is primarily used for monitoring and management but does not establish a terminal session like Telnet does. HTTP (HyperText Transfer Protocol) is typically utilized for web services and accessing resources on the web, whereas FTP (File Transfer Protocol) primarily focuses on file transfers. These functions are essential in various use cases but do not serve the same purpose as Telnet in establishing a command-line interface connection essential for the automated processes that pyATS was designed to facilitate.
