Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q65-Q70):NEW QUESTION # 65
Which two statements are correct about the Junos REST API Explorer? (Choose two.)
Answer: B,D
Explanation:
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.

NEW QUESTION # 66
What is the correct sequence for Python script execution?
Answer: D
Explanation:
Python follows a specific execution flow when a script is run:
The code is interpreted:
Python is an interpreted language, meaning that the Python interpreter reads the code line by line. When a Python script is executed, the interpreter first reads the source code.
The code is translated to bytecode:
After interpreting the source code, Python translates it into bytecode. Bytecode is an intermediate representation of the source code that is portable and efficient for execution by the Python Virtual Machine (PVM).
The bytecode is executed in runtime:
Finally, the Python Virtual Machine (PVM) executes the bytecode. The PVM is a part of the Python runtime environment, responsible for interpreting the bytecode into machine-specific instructions for execution.
Hence, the correct sequence is: interpreted ¡ú translated to bytecode ¡ú bytecode executed in runtime.
Why the Other Options Are Incorrect:
Options A, C, and D present an incorrect order of the script execution process, especially in how bytecode is generated and executed.
Reference:
Python's documentation on the interpreter and its execution model explains this standard process.

NEW QUESTION # 67
You want to use a Python package or module.
In this scenario, which statement would accomplish this task?
Answer: A
Explanation:
In Python, to use a package or module, you use the import statement. This statement allows you to load a module into your script so that you can use its functions, classes, and variables. For example, if you wanted to use the math module, you would write import math. This makes all the functions and constants in the math module available for use in your program.
Option A (reap), B (dir), and C (input) do not serve the purpose of importing modules. dir is used to list the attributes of an object, input is used to get user input, and reap is not a valid Python command related to importing modules.
Supporting Reference:
Python Documentation on Imports: The Python documentation provides clear guidelines on how to use the import statement to include modules in your Python scripts.

NEW QUESTION # 68
What is the default port for NETCONF connections over SSH?
Answer: D
Explanation:
https://www.juniper.net/document ... ssh-connection.html The IANA-assigned port for NETCONF-over-SSH sessions is 830.

NEW QUESTION # 69
Which two statements are correct about using the Junos REST API? (Choose two.)
Answer: A,B
Explanation:
* 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.
