Aneventscript is used to automate responses to system events in Junos, such as an interface going down. These scripts are triggered automatically when a specified event occurs, making them suitable for tasks like monitoring interface status and executing actions when the status changes.

Option B (event)is correct because event scripts are designed for reacting to system events like an interface going down.

Option A (commit)is used for configuration changes,Option C (operation)is used for operational tasks, andOption D (SNMP)is not applicable in this context.

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

Data Formats (C): The information can be retrieved inXMLorJSONformats. 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, andOption B is incorrectbecause 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.

In Junos OS, acommit scriptis an on-box automation script that runs every time a configuration change is committed. Commit scripts are used to enforce configuration policies, validate configuration changes, or make automatic adjustments to configurations when certain conditions are met.

Commit Script (C): Executes automatically during the commit process, ensuring that the new configuration adheres to specific rules or conventions before it is applied to the system.

Event, SNMP, and operation scriptsare used for other purposes in Junos automation but do not run automatically with every configuration change.

Junos OS Automation Scripts Guide: Provides details on different types of scripts, including commit scripts, and their use cases.

Juniper Networks Documentation: Offers examples and best practices for creating and using commit scripts.
