Juniper Automation and DevOps, Associate (JNCIA-DevOps) JN0-224 Prüfungsfragen mit Lösungen (Q25-Q30):25. Frage
Which two statements are correct about the Junos REST API Explorer? (Choose two.)
  • A. The REST API Explorer supports multiple RPC calls.
  • B. The REST API Explorer is enabled by default on all Junos devices.
  • C. The REST API Explorer supports both GET and POST calls.
  • D. The REST API Explorer returns data only in XML format.
Antwort: A,C
Begründung:
The Junos REST API Explorer provides an interactive environment to explore and execute REST API calls. The correct statements are:
Supports GET and POST Calls (C): The REST API Explorer allows users to make both GET and POST requests, enabling retrieval and submission of data to the Junos device.
Supports Multiple RPC Calls (D): The REST API Explorer can execute multiple RPC (Remote Procedure Call) commands, allowing a wide range of operations to be performed directly through the interface.
Option A is incorrect because the REST API Explorer is not enabled by default; it must be enabled manually. Option B is incorrect because the REST API Explorer returns data in both XML and JSON formats, not just XML.
Reference:
Junos REST API Explorer Documentation: Provides details on the supported operations and how to use the Explorer for different types of requests.
Juniper Networks Documentation: Covers the setup and usage of the REST API Explorer.

26. Frage
Which two PyEZ object methods are included by default when using a Python context manager? (Choose two.)
  • A. |load() and commit ()
  • B. pdiff() and diff()
  • C. lock () and unlock (>
  • D. open() and close()
Antwort: C,D
Begründung:
When using a Python context manager with Junos PyEZ, two key methods are automatically included:
open() and close(): These methods are used to establish and terminate a connection to a Junos device. When you use a context manager (the with statement), open() is called when entering the block, and close() is called when exiting, ensuring the connection is properly managed.
lock() and unlock(): These methods are used to lock the configuration database to prevent other users from making changes while you are working on it. When using a context manager, lock() is called at the start of the block, and unlock() is called at the end, ensuring safe configuration changes.
Supporting Reference:
Junos PyEZ Documentation: The documentation explains how context managers work in PyEZ, including the automatic invocation of open(), close(), lock(), and unlock() methods.

27. Frage
Which two statements are correct about using the Junos REST API? (Choose two.)
  • A. It must use SSH for a connection.
  • B. It supports data In CSV format.
  • C. NETCONF is not supported.
  • D. It is a simple configuration.
Antwort: B,D
Begründung:
* A. It supports data in CSV format:
The Junos REST API supports multiple data formats for transferring information between systems, including XML, JSON, and CSV (Comma Separated Values). This flexibility allows for easier data parsing, especially in environments where structured data (like CSV) is a standard. CSV is often used for bulk data export or import and reporting purposes, making it an essential format for automation tasks involving external systems or large datasets.
Example Usage in REST API:
When using the Junos REST API, a user can request configuration or operational data and specify the response format (XML, JSON, or CSV). CSV is particularly useful when integrating Junos devices with systems that require easily readable, tabular formats.
Reference:
* D. It is a simple configuration:
The Junos REST API is designed to be relatively simple to configure. Once the REST API service is enabled on the Junos device, it can be accessed via HTTP or HTTPS, making it an easy entry point for automation and management tasks. Unlike more complex protocols (such as NETCONF), the REST API is lightweight and easier to use for simple configuration changes and retrieving operational data.
Configuration Example:
To enable the REST API, you can add the following configuration:
set system services rest http
set system services rest https
After enabling the service, API requests can be made to interact with the device for automation tasks, without needing the complexity of SSH or NETCONF configuration.
Why the Other Options Are Incorrect:
B . It must use SSH for a connection: This is incorrect. The Junos REST API uses HTTP or HTTPS for communication, not SSH. While SSH is commonly used for NETCONF, it is not required for REST API connections. REST APIs operate over standard web protocols.
C . NETCONF is not supported: This is incorrect. Junos supports both REST API and NETCONF for automation and configuration management. NETCONF is an XML-based protocol used for device configuration, which operates over SSH. The REST API and NETCONF can coexist on the same device, offering multiple avenues for automation.
Juniper Automation in DevOps Context: The simplicity and flexibility of the Junos REST API make it ideal for DevOps automation tasks. It allows teams to easily interact with Junos devices using lightweight RESTful methods, integrating with external systems through formats like CSV. The ease of configuration supports rapid deployment and scaling of automated management tasks.

28. Frage
Which feature is used in XML to ensure that all attributes and elements have unique names?
  • A. namespace
  • B. selectors
  • C. XPath
  • D. predicate
Antwort: C

29. Frage
What is the correct Python script syntax to prompt for input?
  • A. hostIP = input("Device IP address: ")
  • B. input("Device IP address: ") = hostIP
  • C. hostIP = input"Device IP address: "
  • D. hostIP = input{Device IP address: }
Antwort: A
Begründung:
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.
