What is a common use case for scripting with the Junos REST API?

Replacing the need for network monitoring tools

Providing a graphical interface for network administrators

Automating the collection of device configuration and operational data

Managing physical hardware components

A network administrator is configuring a Junos device to allow a specific automation server to access the REST API. The administrator wants to restrict access to only the automation server's IP address. Which security mechanism should be used?

Use HTTPS with a self-signed certificate

Configure a firewall filter on the loopback interface to allow only the automation server's IP

Disable the REST API on all interfaces except the management interface

Set the REST API to listen only on a specific port

A developer is building a web application that needs to display real-time interface traffic statistics from a Junos device. The application must minimize bandwidth and parsing overhead. Which data format and HTTP method should the developer use?

JSON with GET to /rpc/get-interface-traffic-statistics

XML with GET to /rpc/get-interface-traffic-statistics

XML with POST to /rpc/get-interface-traffic-statistics

JSON with POST to /rpc/get-interface-traffic-statistics

A security team requires that all REST API traffic to Junos devices be encrypted and that the automation server authenticate using a client certificate. The Junos device currently has a self-signed certificate for HTTPS. Which additional configuration is required to meet the requirement?

Disable HTTP and only allow HTTPS

Use basic authentication over HTTPS

Use token-based authentication with the token sent over HTTPS

Configure the device to require client certificates and trust the automation server's CA

In the Junos REST API, what does the resource path '/configuration/interfaces/interface' typically represent?

The operational status of all interfaces

A list of all configured interfaces on the device

A single interface named 'interface'

The configuration of the management interface only

Junos REST API JN0-224 Practice Questions (Page 6)

Part of the REST API domain, which makes up ~17% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~6–10 in this domain), expect 2–3 from this objective — we provide 33 practice questions to prepare you well beyond it.
