JN0-224 Exam Questions & Answers

Junos on-box scripting supports the following programming languages:

SLAX (C): SLAX (Structured Language for XML) is a scripting language designed specifically for Junos devices. It allows for easy manipulation of XML data, making it ideal for creating Junos scripts that interact with device configurations.

XSLT (D): XSLT (Extensible Stylesheet Language Transformations) is another language used for transforming XML documents into other formats. It is commonly used in Junos for transforming XML data into different views or outputs.

Options A (Perl) and B (Ruby) are not used for Junos on-box scripting. While these languages are popular in other contexts, Junos scripting relies heavily on XML-based languages like SLAX and XSLT.

Junos XML API and Scripting Guide: Describes the use of SLAX and XSLT for on-box scripting.

Juniper Networks Automation Documentation: Provides examples and best practices for using SLAX and XSLT in Junos scripting.

The IANA-assigned port for NETCONF-over-SSH sessions is 830.

In Junos PyEZ, the Config object provides various methods for interacting with device configurations. Two of the key methods are:

lock(): This method locks the candidate configuration database to prevent other users or processes from making changes while you are modifying the configuration.

config(): This method is used to create a Config object that represents the configuration database, allowing you to load, modify, and commit configuration changes.

Option C (lock) and Option D (config) are correct because they are valid methods provided by the PyEZ Config object.

Option A (commie) and Option B (device) are incorrect as they are not methods of the Config object.
