When using the REST API to retrieve interface configuration information from a Junos device:

Data Formats (C): The information can be retrieved in XML or JSON formats. These are the two standard data formats supported by the Junos REST API for representing configuration and operational data.

Authentication (D): For each HTTP request, especially when using tools like cURL, authentication information must be included. This is typically done using basic authentication (username and password) or an authentication token.

Option A is incorrect because HTML is not a supported format for REST API data retrieval in Junos, and Option B is incorrect because SSH is not required for REST API requests; the REST API typically uses HTTP/HTTPS.

Junos REST API Documentation: Details the data formats (XML, JSON) supported by the Junos REST API and the need for authentication.

cURL Usage with REST API: Provides examples of how to use cURL with Junos REST API, including the necessity of providing authentication.
