NEW QUESTION # 20
Which statement is valid regarding YAML and JSON?
Answer: A
Explanation:
Both YAML and JSON are case-sensitive, meaning that the distinction between uppercase and lowercase characters matters. For example, in JSON or YAML, Key and key would be considered different.
Option D (case-sensitive) is correct because both YAML and JSON treat keys and values with different cases as distinct.
Option A is incorrect because, while JSON does not use indentation, YAML does rely on indentation to define structure. Option B is incorrect because whitespace can be significant in YAML for structure, and Option C is incorrect because JSON does not support comments, while YAML does.
Supporting Reference:
YAML and JSON Documentation: The official specifications for both YAML and JSON emphasize their case sensitivity.
NEW QUESTION # 21
Which two PyEZ object methods are included by default when using a Python context manager? (Choose two.)
Answer: C,D
Explanation:
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.
NEW QUESTION # 22
What are two Junos PyEZ configuration object methods? (Choose two.)
Answer: A,B
Explanation:
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.
Supporting Reference:
Junos PyEZ Documentation: Details the methods available in the Config object, including lock() and config().
NEW QUESTION # 23

NEW QUESTION # 24
You must use Junos PyEZ to configure unique IP addresses on individual machines.
Which two features will permit this requirement? (Choose). Ian SCP module
Answer: C,D
Explanation:
To configure unique IP addresses on individual machines using Junos PyEZ, you can use the following features:
YAML Data File (C): YAML files are used to store configuration data in a human-readable format. They are often used in combination with Jinja2 templates to provide the data necessary for template rendering.
Jinja2 Template (D): Jinja2 is a templating engine for Python that allows you to create dynamic templates. When used with Junos PyEZ, a Jinja2 template can be filled with data (such as IP addresses from a YAML file) to generate configuration snippets that are applied to different devices.
Options A (SCP module) and B (BSON data file) are not typically used with Junos PyEZ for this purpose.
Reference:
Junos PyEZ Documentation: Discusses the use of YAML files and Jinja2 templates for generating configurations.
Jinja2 Templating Documentation: Provides details on how to create and use templates in Python scripts.
