Which two statements are true about an XML schema document? (Choose two.)

A. It is formatted as an XLT file.

B. It cannot be examined in the Junos CLI.

C. It is an authoritative source for operational and configuration XML.

D. lit is formatted as an XSD file.

C. It is an authoritative source for operational and configuration XML.

D. lit is formatted as an XSD file.

Explanation:

An XML schema document (XSD) is a key component in defining the structure and constraints of XML data used in various applications, including Junos:

Authoritative Source (C): An XML schema document serves as the authoritative definition of the structure, content, and semantics of XML documents. It ensures that the XML data adheres to specific rules and formats, which is essential for both operational and configuration XML.

XSD Format (D): XML schema documents are typically written in the XSD (XML Schema Definition) format, which provides a formal description of the XML document's structure.

Option A is incorrectbecause XML schemas are not formatted as XLT files (which are related to XSLT transformations), andOption B is incorrectbecause XML schemas can indeed be examined in the Junos CLI using appropriate commands.

W3C XML Schema Definition Language (XSD) Documentation: Provides comprehensive information on the XSD format.

Juniper Networks Documentation: Discusses the role of XML schemas in managing Junos configurations.

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

A. TheREST API Explorer is enabled bydefault on all Junos devices.

B. The REST API Explorer returns data only in XML format.

C. The REST API Explorer supports both GET and POST calls.

D. The REST API Explorer supports multiple RPC calls.

C. The REST API Explorer supports both GET and POST calls.

D. The REST API Explorer supports multiple RPC calls.

Explanation:

The Junos REST API Explorer provides an interactive environment to explore and execute REST API calls. The correct statements are:

Supports GET and POST Calls (C): The REST API Explorer allows users to make both GET and POST requests, enabling retrieval and submission of data to the Junos device.

Supports Multiple RPC Calls (D): The REST API Explorer can execute multiple RPC (Remote Procedure Call) commands, allowing a wide range of operations to be performed directly through the interface.

Option A is incorrectbecause the REST API Explorer is not enabled by default; it must be enabled manually.Option B is incorrectbecause the REST API Explorer returns data in both XML and JSON formats, not just XML.

Junos REST API Explorer Documentation: Provides details on the supported operations and how to use the Explorer for different types of requests.

Juniper Networks Documentation: Covers the setup and usage of the REST API Explorer.

You are using the curl tool to include multiple RPCs in a REST API request. Which HTTP method must be used for this request?

A. GET

B. PUT

C. POST

D. HEAD

C. POST

You are asked to use the REST API to retrieve interface configuration information from your Junos device. You decide to use a cURL HTTP GET command to retrieve this information. In this scenario, which statement is correct?

A. The request is handled by the mod process runningon the Junos device.

B. The request is handled by the isrpd process runningon the Junos device.

C. The request is handled by the rpd process runningon the Junos device.

D. The request is handled by the isd process runningon the Junos device

B. The request is handled by the isrpd process runningon the Junos device.

Explanation:

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.
