You want to use a Python package or module.

In this scenario, which statement would accomplish this task?

  1. reap
  2. dir
  3. input
  4. Import

Answer(s): D

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.

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.



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.)

  1. Limit management access to only SSH
  2. Limit management access to specific users.
  3. Limit the number of simultaneous connections.
  4. Limit access to only certain source IP addresses

Answer(s): C,D

Explanation:

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.

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.



Which statement is true regarding Junos automation capabilities for device provisioning?

  1. The Junos REST API client is on-box.
  2. Junos automation does not allow for device provisioning throuqh the console port.
  3. Junos automation allows for device provisioning through the console port.
  4. The Junos REST API client is off-box.

Answer(s): C

Explanation:

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.



Which two statements are correct about using the Junos REST API? (Choose two.)

  1. It supports data In CSV format.
  2. It must use SSH for a connection.
  3. NETCONF is not supported.
  4. It is a simple configuration.

Answer(s): B,D

Explanation:

The Junos REST API provides a simple configuration method for interacting with Junos devices programmatically. It requires an SSH connection for secure communication between the client and the Junos device.

Option B is correct because the Junos REST API relies on SSH for secure connections.

Option D is correct as the Junos REST API is designed to be easy to configure and use, allowing for straightforward interaction with Junos devices.

Option A (It supports data in CSV format) is incorrect; the REST API typically uses JSON or XML for data exchange.

Option C (NETCONF is not supported) is incorrect as Junos REST API can work alongside NETCONF.
