Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q34-Q39):

NEW QUESTION # 34
Which two statements about the REST API are correct? (Choose two.)

A. The REST API application is stateful.
B. The TCP session state is maintained by the server.
C. The REST API application is stateless.
D. The TCP session state is maintained by the client

Answer: C,D

Explanation:
REST (Representational State Transfer) is an architectural style for designing networked applications, and its key principles include:
Statelessness (B): Each request from the client to the server must contain all the information needed to understand and process the request. The server does not store any session state between requests, meaning each request is independent and does not rely on previous ones.
TCP Session State (C): While REST itself is stateless, the underlying TCP connection's state, such as keeping the connection alive or managing retries, is handled by the client. The server does not retain information about the TCP connection beyond the processing of the individual request.
Options A and D are incorrect because they imply that the REST API is stateful, which contradicts the stateless nature of REST.
Reference:
REST API Design Principles: Describes the stateless nature of REST and the responsibility of clients in managing session state.
Web Development Documentation: Discusses how REST APIs operate, focusing on statelessness and client-server interaction.

NEW QUESTION # 35
Which two statements are correct about the Junos REST API Explorer? (Choose two.)

A. The REST API Explorer supports both GET and POST calls.
B. The REST API Explorer returns data only in XML format.
C. The REST API Explorer supports multiple RPC calls.
D. The REST API Explorer is enabled by default on all Junos devices.

Answer: A,C

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 # 36
You want to use a Python package or module.
In this scenario, which statement would accomplish this task?

A. dir
B. input
C. Import
D. reap

Answer: C

Explanation:
In Python, to use a package or module, you use theimportstatement. 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 themathmodule, you would writeimport math. This makes all the functions and constants in themathmodule available for use in your program.
* Option A (reap), B (dir), and C (input)do not serve the purpose of importing modules.diris used to list the attributes of an object,inputis used to get user input, andreapis not a valid Python command related to importing modules.
Supporting References:
* Python Documentation on Imports:The Python documentation provides clear guidelines on how to use theimportstatement to include modules in your Python scripts.

NEW QUESTION # 37
Junos supports which two APIs for on-box scripting? (Choose two.)

A. XML
B. JET
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.
