Free Juniper JN0-223 Exam Actual Questions

Note: Premium Questions for JN0-223 were last updated On Nov. 29, 2024 (see below)

Question #1

YAML uses which two data structures? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: B, C

YAML (YAML Ain't Markup Language) primarily uses two data structures:

Mappings: These are key-value pairs, similar to dictionaries or hashes in programming languages. In YAML, mappings are used to represent associative arrays or objects. They are defined with a colon (:) separating the key from the value.

Example:

key: value

name: John Doe

Sequences: These are ordered lists of items, equivalent to arrays or lists in other programming languages. Sequences in YAML are denoted by a dash (-) followed by a space and then the item.

Example:

fruits:

- Apple

- Banana

- Cherry

Detailed Explanation:

Mappings (B) allow you to define relationships between keys and values, making it possible to represent more complex data structures like dictionaries or objects.

Sequences (C) allow you to represent ordered collections, which is important for listing elements that must maintain a specific order.

YAML is often used in configuration files and data serialization in DevOps environments, such as in Ansible playbooks, Kubernetes manifest files, and CI/CD pipeline definitions. Its simplicity and human-readable format make it a popular choice for these applications.


YAML Official Documentation: YAML's specification outlines these core data structures.

Juniper Automation and DevOps Documentation: Provides best practices for using YAML in network automation scripts and configuration management.

Question #2

Which two processes are used by Junos automation? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: B, C

In Junos OS, automation processes are integral to the system's ability to manage network operations efficiently. The following processes are used by Junos automation:

jsd (Junos XML API Server Daemon): This process is crucial for handling XML API requests, which are essential for automation tasks. The jsd process manages interactions between the Junos XML API and the Junos OS, enabling automation scripts to query and configure network devices using XML-formatted commands.

ifd (Interface Daemon): While ifd is primarily responsible for managing network interfaces, it is involved in automation through its role in the operational state of the network. Automation scripts often need to interact with network interfaces to retrieve status information or modify configurations, making ifd a critical component.

Other options like mod and kmd are not directly related to the primary automation processes in Junos OS. mod is related to chassis management, and kmd handles security services.


Juniper Networks Automation and DevOps Documentation: Provides detailed descriptions of processes like jsd and ifd and their roles in Junos OS.

Junos OS Daemons Documentation: Outlines the purpose and functionality of various daemons, including jsd and ifd.

Question #3

You want to use a Python package or module.

In this scenario, which statement would accomplish this task?

Reveal Solution Hide Solution
Correct Answer: D

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.


Question #4

Using the set rest control configuration command, what are two ways to control access to the REST API running on a Junos device? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: C, D

When using the set rest control configuration command on a Junos device, you have several options to control access to the REST API. Two effective methods include:

Limiting the number of simultaneous connections: This ensures that the REST API is not overwhelmed by too many concurrent requests, which could potentially lead to performance issues or denial of service.

Limiting access to certain source IP addresses: This method restricts API access to specific IP addresses, enhancing security by ensuring that only trusted sources can interact with the REST API.

Option A (Limit management access to only SSH) is unrelated to controlling REST API access specifically.

Option B (Limit management access to specific users) might be relevant in a different context, but it is not directly tied to REST API control via the specific command mentioned.

Supporting Reference:

Juniper Networks REST API Documentation: This documentation explains how to configure and control access to the REST API on Junos devices, including connection limits and IP-based access control.


Question #5

A. The Junos REST API client is on-box.

Reveal Solution Hide Solution
Correct Answer: C

Junos automation provides several methods for device provisioning, including through the console port. This allows network administrators to automate the initial configuration of devices even before they are connected to the network. This method is particularly useful for scenarios where remote devices need to be provisioned before they are fully integrated into the network.

Option A (The Junos REST API client is on-box) and Option D (The Junos REST API client is off-box) describe the REST API client's location but do not address device provisioning through the console port.

Option B (Junos automation does not allow for device provisioning through the console port) is incorrect because Junos automation does support such provisioning.

Supporting Reference:

Juniper Networks Automation and Provisioning Documentation: This documentation includes examples and instructions for provisioning devices through various methods, including the console port.
