Juniper JN0-223 Exam With Confidence Using Practice Dumps

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.

When using theset rest control configurationcommand 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.

When using a Python context manager with Junos PyEZ, two key methods are automatically included:

open()andclose(): These methods are used to establish and terminate a connection to a Junos device. When you use a context manager (thewithstatement),open()is called when entering the block, andclose()is called when exiting, ensuring the connection is properly managed.

lock()andunlock(): 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, andunlock()is called at the end, ensuring safe configuration changes.
