Question 1

Why is a REST API considered stateless?

AThe client requests to the server do not include state information.

BThe REST API is an international API.

CNo client context is stored on the server between requests.

DThe state of the server is not important when making requests.

Answer : A

Question 2

Which two statements about Ansible are correct? (Choose two.)

AAnsible can use a single playbook to configure devices from multiple vendors.

BAnsible modules must be written in Go.

CAnsible is an open source project.

DAnsible requires a license to unlock full functionality.

Answer : A, C

Question 3

What will determine which data serialization format is used for interfacing with a system?

Athe system's API

Bthe operating system

Cprogramming language version

DIDE specifications

Answer : A

Question 4

You want to perform a dry run on the myPlays playbook and use a custom inventory file called myRouters.ini.

Which Ansible command would you use in this scenario?

Aansible-playbook myPlays --check -i myRouters.ini

Bansible-playbook myPlays ---extra-vars 'inventory_file=myRouters .ini'

Cansible-playbook myPlays ---extra-vars 'dry run=True' myRouters.ini

Dansible-playbook myPlays ---limit myRouters

Answer : B

Question 5

Exhibit.

Referring to the exhibit, which statement about REST is correct?

AThe device is configured to allow only two simultaneous REST connections.

BThe device is configured to allow connections from the REST API Explorer

CThe device is configured to allow HTTP connections on port 3030.

DThe device is configured to allow HTTPS connections on port 3443.

Answer : D

Question 6

Which two tools would you use to make REST API requests? (Choose two.)

AcURL

BNETCOfJF

CWeb browser

DSSH

Answer : A, C

REST API requests can be made using various tools that support HTTP methods. Two common tools are:

cURL: A command-line tool that allows you to send HTTP requests, including GET, POST, PUT, and DELETE. It is widely used for testing and interacting with RESTful APIs due to its simplicity and flexibility.

Web Browser: Modern web browsers can be used to send HTTP GET requests directly by entering the URL into the address bar. Additionally, browser extensions like Postman or built-in developer tools can be used to construct and send more complex REST API requests.

Option B (NETCOfJF) is incorrect as it does not refer to a standard tool for making REST API requests.

Option D (SSH) is incorrect because SSH is a protocol used for secure remote login and command execution, not for sending REST API requests.

Supporting Reference:

cURL Documentation: Official cURL documentation provides extensive information on how to use cURL to interact with REST APIs.

Web Development and REST API Guides: Many web development resources and REST API documentation recommend using web browsers and tools like cURL for testing and interacting with APIs.

Question 7

Which two statements about NETCONF layers are correct? (Choose two.)

ANETCONF layers use the messages layer to receive RPCs from a remote NETCONF server.

BNETCONF layers use the messages layer to send RPCs to a remote NETCONF server.

CNETCONF layers use the operations layer to receive RPCs from a remote NETCONF server.

DNETCONF layers use the operations layer to send RPCs to a remote NETCONF server.

Answer : B, C

NETCONF (Network Configuration Protocol) is a standard protocol defined for managing network devices. NETCONF operates in a layered architecture, which includes the following key layers:

Operations Layer: This layer deals with the actual operations like <get-config>, <edit-config>, <copy-config>, and others. It receives RPC (Remote Procedure Call) requests from a remote NETCONF client and processes these requests.

Messages Layer: This layer is responsible for encoding the RPCs and sending them over the network. It handles the communication between the NETCONF client and server, ensuring that the RPC messages are correctly formatted (usually in XML) and transmitted.

Statement B is correct because the Messages layer is responsible for sending RPCs to a remote NETCONF server.

Statement C is correct because the Operations layer is where the NETCONF server receives and processes the RPCs sent by the client.

Supporting Reference:

Juniper Networks NETCONF Documentation: Provides a detailed breakdown of the NETCONF protocol layers and their functions.

RFC 6241: The official specification for NETCONF, which describes the layered architecture, including the operations and messages layers.
