Which two data structures are used in JSON? (Choose two.)
- A. tuples
- B. dictionaries
- C. arrays
- D. objects
Answer: C,D
Explanation:
In JSON (JavaScript Object Notation), the two primary data structures are:
Objects: These are collections of key-value pairs, where each key is a string, and the value can be a string, number, array, boolean, or another object. In Python, this structure is analogous to a dictionary.
Arrays: These are ordered lists of values, where each value can be of any data type, including another array or object. In Python, this structure is similar to a list.
Option A (tuples) and Option D (dictionaries) refer to Python-specific data structures and are not directly used in JSON.
Supporting Reference:
JSON Documentation and Tutorials: JSON objects and arrays are the standard data structures used in this format, as described in many tutorials and the official JSON documentation.
NEW QUESTION # 24
Which type of on-box automation script is designed to run every time a user executes a configuration change?
- A. commit
- B. SNMP
- C. event
- D. operation
Answer: A
Explanation:
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.

NEW QUESTION # 30
You are asked to use the REST API to retrieve interface configuration information from your Junos device.
You decide to use a cURL HTTP GET command to retrieve this information.
In this scenario, which two statements are correct? (Choose two.)
- A. You can retrieve this data in HTML or JSON formats.
- B. You must have SSH enabled on the Junos device.
- C. You must Include the authentication Information with each request.
- D. You can retrieve this data in XML or JSON formats.
Answer: C,D
Explanation:
When using the REST API to retrieve interface configuration information from a Junos device:
* Data Formats (C): The information can be retrieved inXMLorJSONformats. These are the two standard data formats supported by the Junos REST API for representing configuration and operational data.
* Authentication (D): For each HTTP request, especially when using tools like cURL,authentication information must be included. This is typically done using basic authentication (username and password) or an authentication token.
Option A is incorrect because HTML is not a supported format for REST API data retrieval in Junos, andOption B is incorrectbecause SSH is not required for REST API requests; the REST API typically uses HTTP/HTTPS.
* Junos REST API Documentation: Details the data formats (XML, JSON) supported by the Junos REST API and the need for authentication.
* cURL Usage with REST API: Provides examples of how to use cURL with Junos REST API, including the necessity of providing authentication.

NEW QUESTION # 31
Which two statements about NETCONF are true? (Choose two.)
- A. It uses the messages layer to lock the configuration of a Junos device.
- B. It uses the operations layer to commit the configuration of a Junos device.
- C. It uses the messages layer to commit the configuration of a Junos device.
- D. It uses the operations layer to lock the configuration of a Junos device.
Answer: B,D
Explanation:
NETCONF (Network Configuration Protocol) operates through different layers, with the operations layer being particularly important for managing configurations:
* Operations Layer (A & D): This layer is responsible for actions like locking and committing the configuration on a Junos device. The lock operation prevents other sessions from modifying the configuration, and the commit operation applies the configuration changes to the device.
Options B and Care incorrect because the messages layer handles the communication aspects, such as exchanging data between the client and server, not performing configuration operations like locking and committing.
* IETF RFC 6241 (NETCONF): Describes the protocol layers and their functions, with a focus on the operations layer.
* Juniper Networks NETCONF Documentation: Provides insights into how NETCONF operations are managed in Junos References:

NEW QUESTION # 33
You want to use a Python package or module.
In this scenario, which statement would accomplish this task?
- A. input
- B. Import
- C. reap
- D. dir
Answer: B
Explanation:
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.

You are asked to use the REST API to retrieve interface configuration information from your Junos device.
You decide to use a cURL HTTP GET command to retrieve this information.
In this scenario, which statement is correct?
- A. The request is handled by the rpd process runningon the Junos device.
- B. The request is handled by the isd process runningon the Junos device
- C. The request is handled by the isrpd process runningon the Junos device.
- D. The request is handled by the mod process runningon the Junos device.
Answer: C
Explanation:
When using the REST API on a Junos device, theisrpd(Integrated Service Routing Process Daemon) process is responsible for handling REST API requests. This process listens for incoming HTTP requests and processes them accordingly, including retrieving interface configuration information when a GET request is made.
* Option Bis correct because theisrpdprocess handles the REST API requests on a Junos device.
* Options A (mod process), C (rpd process), and D (isd process)are incorrect in this context as they either do not exist or serve different purposes on a Junos device.
Supporting References:
* Juniper Networks REST API Documentation:Provides insights into how REST API requests are managed and processed by theisrpdprocess on Junos devices.
