What are two important aspects of the DevOps culture? (Choose two.)
Answer(s): A,D
Two important aspects of the DevOps culture are:Communication (A): In a DevOps environment, continuous and effective communication between development, operations, and other stakeholders is crucial. It ensures that everyone is aligned, reduces misunderstandings, and facilitates faster and more efficient workflows.People (D): DevOps is as much about the people as it is about the processes and tools. The culture emphasizes collaboration, shared responsibility, and a mindset focused on continuous improvement. Empowering people to work together across different disciplines is at the heart of DevOps.Options B and C are not primary aspects of the DevOps culture. While tools are essential in implementing DevOps practices, the culture emphasizes communication and collaboration among people more than the use of specific tools or rigid separation of duties.

You are asked to use the REST API to retrieve interface configuration information from your Junos device. You decide to use a cURL HTTP GET command to retrieve this information.In this scenario, which two statements are correct? (Choose two.)
Answer(s): C,D
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 RESTAPI 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.
Which two programming languages are used for Junos on-box scripting? (Choose two.)
Junos on-box scripting supports the following programming languages:SLAX (C): SLAX (Structured Language for XML) is a scripting language designed specifically for Junos devices. It allows for easy manipulation of XML data, making it ideal for creating Junos scripts that interact with device configurations.XSLT (D): XSLT (Extensible Stylesheet Language Transformations) is another language used for transforming XML documents into other formats. It is commonly used in Junos for transforming XMLdata into different views or outputs.Options A (Perl) and B (Ruby) are not used for Junos on-box scripting. While these languages are popular in other contexts, Junos scripting relies heavily on XML-based languages like SLAX and XSLT.
Junos XML API and Scripting Guide: Describes the use of SLAX and XSLT for on-box scripting.Juniper Networks Automation Documentation: Provides examples and best practices for using SLAX and XSLT in Junos scripting.
Which process is responsible for XML automation requests?
Answer(s): B
The mgd (Management Daemon) process in Junos is responsible for handling XML automation requests. This daemon manages the configuration and operational commands received via NETCONF, which uses XML for data exchange. The mgd process parses the XML data and applies the necessary configuration or retrieves the requested information.Option B is correct because mgd is the process that handles XML-based requests in Junos.Options A (jsrpd), C (rpd), and D (jsd) are incorrect because they are responsible for different functions, such as routing protocols and services, not XML automation.
Juniper Networks Management Daemon (mgd) Documentation: Provides an overview of the responsibilities of the mgd process, including handling XML requests.
Which Junos configuration database is updated by PyEZ by default?
Answer(s): C
An event script 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, and Option D (SNMP) is not applicable in this context.
