Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q26-Q31):NEW QUESTION # 26
Junos supports which two APIs for on-box scripting? (Choose two.)
  • A. JET
  • B. XML
  • C. Chef
  • D. Puppet
Answer: A,B
Explanation:
Juniper Networks' Junos operating system supports several APIs for on-box scripting, two of which are:
JET (Juniper Extension Toolkit): JET is a modern API framework that provides a programmable interface for interacting with Junos. It allows developers to create custom applications that run directly on Junos devices, enabling the automation of network operations. JET provides both a gRPC and a REST API interface, allowing for flexible integration with external systems.
XML API: The Junos XML API allows direct interaction with the Junos OS through XML-based requests. This API can be used to retrieve information, configure devices, and execute commands on Junos devices. The XML API is crucial for automation tasks as it provides a structured and consistent way to interact with the device's configuration and operational data.
Detailed Explanation:
JET (A) provides high-performance access to Junos routing, switching, and service elements via programmable interfaces. It is highly used for creating custom applications that require tight integration with the Junos OS.
XML (C), on the other hand, is a well-established method for interacting with Junos, especially for legacy systems or when working within environments where XML is the standard data format.
Other options like Puppet (B) and Chef (D) are not APIs provided by Junos for on-box scripting but are configuration management tools used externally to manage Junos devices.
Reference:
Juniper Networks JET Documentation: Provides details on how to leverage JET APIs for automation.
Junos XML Management Protocol Guide: Describes how to use XML for scripting and automating tasks in Junos.
These APIs are key components of Juniper's automation strategy, allowing for scalable, flexible, and efficient network operations.

NEW QUESTION # 27
Which Python operator is used to test if two variables are equal?
  • A. =
  • B. ==
  • C. !=
  • D. %
Answer: B
Explanation:
In Python, the == operator is used to test whether two variables are equal. It returns True if the variables are equal and False if they are not.
Option B (==) is correct because it is the equality operator in Python.
Option A (!=) is used for inequality, Option C (%) is the modulus operator, and Option D (=) is used for assignment, not for testing equality.
Supporting Reference:
Python Documentation on Operators: The official Python documentation covers the use of == for equality checks.

NEW QUESTION # 28
Which DevOps "Three way" principle addresses technical debt?
  • A. feedback
  • B. continuous experimentation and learning
  • C. flow
  • D. continuous experimentation
Answer: A
Explanation:
In the context of the DevOps "Three Ways" principles, the feedback principle directly addresses the management of technical debt.
The "Three Ways" are core principles guiding DevOps practices, and they are as follows:
Flow: Refers to the smooth and fast flow of work through the system, from development to operations.
Feedback: Emphasizes creating effective, fast, and continuous feedback loops between teams to catch issues early, address technical debt, and ensure quality.
Continuous experimentation and learning: Encourages constant experimentation, innovation, and learning from failures to improve systems and processes over time.
Feedback and Technical Debt:
Feedback loops play a crucial role in addressing technical debt. Technical debt refers to the implied cost of additional work that arises when code or system design decisions are made for short-term gains, such as quick fixes or temporary patches. Over time, technical debt can accumulate and degrade system performance, reliability, and maintainability.
The feedback loop ensures that issues related to technical debt (such as poor code quality, design shortcuts, or performance bottlenecks) are caught early in the process, ideally before they become major problems. Continuous monitoring, testing, and reviewing help identify and resolve technical debt incrementally rather than letting it accumulate unchecked.
Automation in feedback loops: In DevOps, automated testing, continuous integration (CI), and monitoring tools provide immediate feedback to developers, highlighting areas where technical debt is increasing. This feedback is crucial for making proactive decisions about refactoring code or improving infrastructure without waiting for problems to manifest in production.
For instance, the feedback loop might expose slowdowns in application performance after each new feature is added. This would trigger a review to either refactor the feature code or improve system resources, preventing further technical debt accumulation.
Flow and Technical Debt:
While flow focuses on the smooth transition of work through the pipeline, it indirectly helps with technical debt by ensuring continuous and streamlined processes. However, feedback mechanisms are the primary tools for identifying and resolving technical debt.
Continuous Experimentation and Learning:
This principle promotes innovation and learning from failures but does not directly address technical debt. The focus here is more on risk-taking and improvement rather than managing or eliminating technical debt.
Reference from DevOps Practices:
The Phoenix Project, a book often referenced in DevOps, discusses how feedback loops are essential for maintaining system integrity and managing technical debt effectively. By improving feedback mechanisms, teams can address small issues before they become costly to fix.
The DevOps Handbook also highlights the importance of feedback in managing technical debt, emphasizing that fast feedback allows for continuous improvement and avoids the accumulation of bad practices that would otherwise lead to technical debt.
Juniper Automation and DevOps Context: Juniper's automation frameworks integrate feedback mechanisms using tools like continuous monitoring and automated testing. These tools help engineers track the health of network systems, identify configuration drifts, and resolve issues before they lead to significant technical debt.

NEW QUESTION # 29
Which two tools would you use to make REST API requests? (Choose two.)
  • A. Web browser
  • B. SSH
  • C. NETCOfJF
  • D. cURL
Answer: A,D
Explanation:
REST API requests can be made using various tools that support HTTP methods. Two common tools are:
cURL: A command-line tool that allows you to send HTTP requests, including GET, POST, PUT, and DELETE. It is widely used for testing and interacting with RESTful APIs due to its simplicity and flexibility.
Web Browser: Modern web browsers can be used to send HTTP GET requests directly by entering the URL into the address bar. Additionally, browser extensions like Postman or built-in developer tools can be used to construct and send more complex REST API requests.
Option B (NETCOfJF) is incorrect as it does not refer to a standard tool for making REST API requests.
Option D (SSH) is incorrect because SSH is a protocol used for secure remote login and command execution, not for sending REST API requests.
Supporting Reference:
cURL Documentation: Official cURL documentation provides extensive information on how to use cURL to interact with REST APIs.
Web Development and REST API Guides: Many web development resources and REST API documentation recommend using web browsers and tools like cURL for testing and interacting with APIs.

NEW QUESTION # 30
Which statement about the NETCONF content layer is true?
  • A. It uses HTML for RPC request and response payloads.
  • B. It uses YAML for RPC request and response payloads.
  • C. It uses XML for RPC request and response payloads.
  • D. It uses JSON for RPC request and response payloads.
Answer: C
Explanation:
The NETCONF protocol, used for network management, utilizes XML for encoding the RPC (Remote Procedure Call) requests and responses. XML is chosen because of its flexibility and ability to represent hierarchical data structures, making it well-suited for representing network configurations and states.
Option B is correct because XML is the standard format used for NETCONF RPC payloads.
Options A (YAML), C (JSON), and D (HTML) are incorrect because these formats are not used by NETCONF for its RPC payloads.
Supporting Reference:
RFC 6241 - NETCONF Protocol: This RFC describes the use of XML for encoding NETCONF messages.
