An automation engineer is building a script that must interact with a Junos device's REST API. The engineer wants to use the Junos REST API Explorer to discover the exact parameter names and data types for a specific RPC before writing the script. The engineer has authenticated to the Explorer. What is the most efficient way to get this information?

Look up the RPC in the device's syslog to see how previous requests were formatted.

Use the CLI command 'show rest api rpc ' to display the RPC's parameters.

Navigate to the RPC in the Explorer and examine the 'Parameters' section, which lists parameter names, types, and whether they are required.

Send a GET request to the RPC without parameters and observe the error message to infer the required parameters.

What does an HTTP status code of 200 indicate in a Junos REST API response?

The device encountered an internal error

The requested resource was not found

An engineer is using the Junos REST API Explorer to send a POST request that modifies the hostname of a device. The engineer fills in the required fields and clicks 'POST'. The response shows a 200 status code with an empty body. What does this mean?

The hostname was successfully changed and committed.

The hostname was changed, but the change was not committed.

The request failed because the response body is empty.

The request was queued and will be applied later.

After sending a request in the Junos REST API Explorer, where is the response displayed?

In a pop-up window on the device's console

In the device's system log file

In a separate response pane within the Explorer interface

In the CLI output of the 'show rest api response' command

What type of information is typically displayed for each endpoint in the Junos REST API Explorer?

The device's current CPU and memory usage

The list of users currently logged into the device

The device's software license keys

The HTTP methods supported, such as GET, POST, PUT, and DELETE
