Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q45-Q50):

NEW QUESTION # 45
Which two programming languages have a NETCONF library supported by Juniper Networks? (Choose two.)

A. Go
B. Ruby
C. Python
D. SLAX

Answer: A,C

Explanation:
Juniper Networks supports NETCONF libraries for several programming languages, including:
Python (B): Python has a well-supported NETCONF library called ncclient, which is widely used for automating network configurations across Junos devices.
Go (C): Go also has a NETCONF library (go-netconf), which provides similar functionalities for managing Junos devices.
Ruby (A) and SLAX (D) do not have widely recognized or supported NETCONF libraries directly from Juniper Networks, making Python and Go the correct choices.
Reference:
Juniper Networks NETCONF Documentation: Lists supported programming languages and libraries for interacting with NETCONF on Junos devices.
ncclient Documentation: The primary Python library for working with NETCONF.

NEW QUESTION # 46
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.
* 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.
Detailed Explanation: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.
* 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.
References:These APIs are key components of Juniper's automation strategy, allowing for scalable, flexible, and efficient network operations.

NEW QUESTION # 48
Which DevOps "Three way" principle addresses technical debt?

A. continuous experimentation
B. flow
C. continuous experimentation and learning
D. feedback

Answer: D

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.
