Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q36-Q41):

NEW QUESTION # 36
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 statement is correct?

  • A. The request is handled by the rpd process runningon the Junos device.
  • B. The request is handled by the isd process runningon the Junos device
  • C. The request is handled by the isrpd process runningon the Junos device.
  • D. The request is handled by the mod process runningon the Junos device.

Answer: C

Explanation:
When using the REST API on a Junos device, theisrpd(Integrated Service Routing Process Daemon) process is responsible for handling REST API requests. This process listens for incoming HTTP requests and processes them accordingly, including retrieving interface configuration information when a GET request is made.
* Option Bis correct because theisrpdprocess handles the REST API requests on a Junos device.
* Options A (mod process), C (rpd process), and D (isd process)are incorrect in this context as they either do not exist or serve different purposes on a Junos device.
Supporting References:
* Juniper Networks REST API Documentation:Provides insights into how REST API requests are managed and processed by theisrpdprocess on Junos devices.


NEW QUESTION # 37
Which DevOps "Three way" principle addresses technical debt?

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

Answer: B

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 # 38
Which statement is correct about YAML?

  • A. YAML uses spaces for indentation
  • B. YAML files must start
  • C. YAML strings must have quotation marks.
  • D. YAML is not case-sensitive.

Answer: A


NEW QUESTION # 39
What is the correct Python script syntax to prompt for input?

  • A. input("Device IP address: ") = hostIP
  • B. hostIP = input"Device IP address: "
  • C. hostIP = input("Device IP address: ")
  • D. hostIP = input{Device IP address: }

Answer: C

Explanation:
In Python, the correct syntax to prompt the user for input and store that input in a variable is:
input(prompt): The input() function is used to take input from the user. The string provided as an argument (inside the parentheses) is displayed as a prompt to the user. The input provided by the user is returned as a string and can be stored in a variable.
Example:
hostIP = input("Device IP address: ")
In this example, "Device IP address: " is the prompt displayed to the user, and the user's input will be stored in the variable hostIP.
Options B, C, and D are syntactically incorrect in Python.
Reference:
Python Official Documentation: Describes the use of the input() function for getting user input.
Python Tutorials: Various tutorials demonstrate how to properly use the input() function in scripts.


NEW QUESTION # 40
Which Python operator is used to test if two variables are equal?

  • A. !=
  • B. %
  • C. =
  • D. ==

Answer: D

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.
