Which of the following is an example of an open source off-box method that network operations teams might use for managing network devices?

Ansible is an example of an open source off-box method that network operations teams can utilize for managing network devices. It is designed to automate IT processes and tasks across various systems, including network devices, servers, and applications. Ansible employs a simple, agentless architecture, allowing network operations teams to define and enforce configurations, deploy changes, and manage tasks efficiently. Due to its open-source nature, it enjoys a strong community support and provides flexibility for customization, making it ideal for organizations looking to enhance their network management capabilities.

In contrast, EEM (Embedded Event Manager) is a feature specific to Cisco devices that facilitates local automation and monitoring directly within the device itself, rather than being an off-box solution. APIC-EM (Application Policy Infrastructure Controller - Enterprise Module) is a Cisco product for policy-based automation of the network but is not open-source. TCL (Tool Command Language) is a scripting language that can be used for control and automation on Cisco devices but is also not classified as an off-box method, as it often runs on the device itself.
