A junior engineer is using the Junos REST API Explorer to retrieve the current configuration of interface ge-0/0/0 on a vMX device. The engineer navigates to the configuration resource, selects the interfaces endpoint, and then clicks 'GET'. What will the Explorer display in the response body?

The operational status and traffic counters for the interface.

A list of all RPCs available for interface management.

A JSON or XML representation of the interface configuration, depending on the selected format.

A prompt to enter the interface name in a separate field before the request can be sent.

In the Junos REST API Explorer, how can you discover the available API endpoints and operations?

By running the 'show rest api endpoints' CLI command

By browsing the interactive documentation and resource list within the Explorer

By reading the device's configuration file directly

By sending a special SNMP request to the device

A network engineer is trying to access the Junos REST API Explorer on a device but receives a 'connection refused' error in the browser. The engineer has already enabled the REST API and can ping the device. What is the most likely cause?

The user's account does not have permission to access the Explorer.

The browser does not support the required JavaScript features.

The device is not running the Junos version that supports the REST API Explorer.

The REST API is listening on a non-default port that is not specified in the URL.

A network engineer wants to use the Junos REST API Explorer to test configuration changes on a lab MX router before writing automation scripts. The engineer has already enabled the REST API on the device and can reach the management interface. What else must be done before the engineer can open the Explorer in a browser and start making requests?

Generate an SSH key pair and configure the public key in the device's user account for API authentication.

Create a local user account with a plain-text password and use those credentials when prompted by the Explorer.

Ensure the device has a valid DNS name that resolves to the management IP and that the browser can reach it.

Install a client certificate on the browser and configure the device to trust that certificate for mutual TLS.

Junos REST API Explorer JN0-224 Practice Questions (Page 1)

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 23 practice questions to prepare you well beyond it.
