An automation script makes a REST API request to modify a Junos configuration. To ensure that the changes are validated and committed in a single workflow step without leaving dangling candidate changes, how can the commit parameter be handled?

An automation developer is designing a tool that interacts with multiple network vendors, including Juniper Junos. They evaluate using Junos REST API versus NETCONF. Which workflow advantage does the REST API offer over NETCONF in web-centric application environments?

A network automation team is using the Junos REST API to manage configurations on a Junos device. They need to perform a commit operation that includes a commit comment and also synchronizes the commit across all Routing Engines in a dual-RE system. Which HTTP method and URI combination should they use to achieve this with a single request?

An automation engineer is tasked with implementing a REST API client that authenticates to a Junos device. The engineer must choose an authentication method supported by the Junos REST API and ensure that credentials are transmitted securely. Which two statements are correct about authentication for the Junos REST API? (Choose two.)

When an automation script issues a POST request to create a new static route via the Junos REST API, what HTTP status code indicates that the resource was successfully created?

When executing a configuration change via the Junos REST API, what is the role of the HTTP DELETE method?

A network automation team is using the Junos REST API to manage configurations on a fleet of Junos devices. They need to ensure that configuration changes are applied atomically and that they can roll back if an error occurs. They decide to use the REST API to load a configuration, commit it, and then verify the commit. Which sequence of REST API calls should they use to load a configuration snippet, commit it, and then confirm the commit was successful?

An automation engineer is writing a Python script that retrieves the operational status of all interfaces from a Junos device using the Junos REST API. The script sends a GET request to https://device/rest/interface. The device returns an HTTP 200 OK response, but the response body is empty. The engineer examines the request and confirms that the URL is correct and the device is reachable. Which action should the engineer take to retrieve the interface status information?
