What are two Junos PyEZ configuration object methods? (Choose two.)

  • A. commie ()
  • B. device ()
  • C. config ()
  • D. lockO

正解：C、D

解説：
In Junos PyEZ, theConfigobject 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 aConfigobject that represents the configuration database, allowing you to load, modify, and commit configuration changes.
* Option C (lock)andOption D (config)are correct because they are valid methods provided by the PyEZConfigobject.
* Option A (commie)andOption B (device)are incorrect as they are not methods of theConfigobject.
Supporting References:
* Junos PyEZ Documentation:Details the methods available in theConfigobject, includinglock() andconfig().

質問 # 41
Which two statements are correct about the Junos REST API Explorer? (Choose two.)

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

正解：A、C

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 incorrectbecause the REST API Explorer is not enabled by default; it must be enabled manually.
Option B is incorrectbecause the REST API Explorer returns data in both XML and JSON formats, not just XML.
* 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.

質問 # 45
A REST API client uses which two HTTP methods to execute RPC requests on the server? (Choose two.)

  • A. CONNECT
  • B. POST
  • C. GET
  • D. HEAD

正解：B、C

解説：
REST APIs use HTTP methods to perform different operations on resources. In the context of RPC (Remote Procedure Call) requests:
* GET:This method is used to retrieve data from the server. In a REST API, it is commonly used to fetch information about resources, such as the current configuration or operational state.
* POST:This method is used to send data to the server to create or update a resource. In the context of RPC, POST is often used to execute a procedure on the server that may result in the modification of a resource or triggering of an action.
Options B (HEAD) and D (CONNECT) are not typically used for executing RPC requests:
* HEADis similar to GET but only retrieves the headers, not the body of the response.
* CONNECTis used to establish a tunnel to the server, primarily for SSL-encrypted communication, and is not commonly associated with RESTful RPC operations.
Supporting References:
* Juniper Networks REST API Documentation:The documentation provides detailed information about the use of HTTP methods in Juniper's RESTful services.
* "RESTful Web Services"by Leonard Richardson and Sam Ruby: This book explains the principles of REST and how different HTTP methods, particularly GET and POST, are used to interact with RESTful APIs.


質問 # 46
You want to use a Python package or module.
In this scenario, which statement would accomplish this task?

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

正解：B

解説：
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.


質問 # 47

質問 # 48
Which two statements about Junos automation are correct? (Choose two.)

  • A. The Junos REST API client is off-box.
  • B. Junos automation does not allow for device provisioning throuqh the console port.
  • C. The Junos REST API client is on-box.
  • D. Junos automation allows for device provisioning through the console port.

正解：C、D

解説：
* A. The Junos REST API client is on-box:The Junos REST API ison-box, meaning it is hosted directly on the Junos OS device. This allows you to interact with the device through RESTful API calls without needing an external client to act as an intermediary. With the on-box REST API, users can manage and automate configuration and operational tasks directly from the Junos device itself using HTTP/HTTPS protocols. This simplifies automation and remote management since the API server is embedded within the device.
Key Automation Capabilities of On-box REST API:
* Supports configuration, monitoring, and operational commands.
* Allows for direct device interaction via tools like curl, or through custom-built automation scripts.

正解：D


質問 # 50
Which type of on-box automation script is designed to run every time a user executes a configuration change?

  • A. commit
  • B. event
  • C. operation
  • D. SNMP

正解：A

解説：
In Junos OS, acommit scriptis an on-box automation script that runs every time a configuration change is committed. Commit scripts are used to enforce configuration policies, validate configuration changes, or make automatic adjustments to configurations when certain conditions are met.
* Commit Script (C): Executes automatically during the commit process, ensuring that the new configuration adheres to specific rules or conventions before it is applied to the system.
Event, SNMP, and operation scriptsare used for other purposes in Junos automation but do not run automatically with every configuration change.
* Junos OS Automation Scripts Guide: Provides details on different types of scripts, including commit scripts, and their use cases.
* Juniper Networks Documentation: Offers examples and best practices for creating and using commit scripts.
