Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q43-Q48):

NEW QUESTION # 43
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 two statements are correct? (Choose two.)

A. You must Include the authentication Information with each request.
B. You must have SSH enabled on the Junos device.
C. You can retrieve this data in XML or JSON formats.
D. You can retrieve this data in HTML or JSON formats.

Answer: A,C

Explanation:
When using the REST API to retrieve interface configuration information from a Junos device:
Data Formats (C): The information can be retrieved in XML or JSON formats. These are the two standard data formats supported by the Junos REST API for representing configuration and operational data.
Authentication (D): For each HTTP request, especially when using tools like cURL, authentication information must be included. This is typically done using basic authentication (username and password) or an authentication token.
Option A is incorrect because HTML is not a supported format for REST API data retrieval in Junos, and Option B is incorrect because SSH is not required for REST API requests; the REST API typically uses HTTP/HTTPS.
Reference:
Junos REST API Documentation: Details the data formats (XML, JSON) supported by the Junos REST API and the need for authentication.
cURL Usage with REST API: Provides examples of how to use cURL with Junos REST API, including the necessity of providing authentication.

NEW QUESTION # 44
Which two statements about NETCONF are correct? (Choose two.)

A. NETCONF cannot use the default SSH port.
B. NETCONF can use the default SSH port.
C. The default port for NETCONF is port 930.
D. The default port for NETCONF is port 830.

Answer: B,D

Explanation:
NETCONF (Network Configuration Protocol) is used for network device management and can operate over SSH. The following are true about NETCONF:
* Default Port 830 (B): By default, NETCONF uses port 830 for communication over SSH. This is the standard port reserved for NETCONF sessions.
* Use of Default SSH Port (D): NETCONF can also operate over the standard SSH port (port 22) if configured to do so. This allows flexibility in network management scenarios where port 830 might not be available or used.
Options A and C are incorrectbecause they refer to incorrect or non-applicable port numbers for NETCONF.
* IETF RFC 6241: Specifies the use of NETCONF over SSH, including port details.
* Juniper Networks NETCONF Documentation: Discusses the configuration and operation of NETCONF on Junos devices, including port usage.

NEW QUESTION # 45
Which statement is correct about DevOps?

A. DevOps is meant to define and restrict the development and operations tools used for a project.
B. DevOps is meant to unite the development, operations, and other teams to improve project collaborations.
C. DevOps is a defined standard written and maintained by the IEEE standards group.
D. DevOps is a collection of strict guidelines that promotes the project completion over all other aspects.

Answer: B

Explanation:
DevOps is a set of practices, tools, and cultural philosophies that aims to integrate and automate the processes between software development and IT operations teams. The primary goal of DevOps is to shorten the systems development life cycle and provide continuous delivery with high software quality.
Option C is correct because DevOps fundamentally focuses on breaking down the silos between development and operations teams, fostering a collaborative environment where these teams work together throughout the entire software lifecycle. This collaboration extends to other stakeholders, including quality assurance (QA), security, and more, to ensure that the product is continuously delivered and improved based on real-time feedback.
DevOps promotes a cultural shift where teams are no longer isolated but work together to share responsibilities, which leads to increased efficiency, faster problem resolution, and a more streamlined deployment process. This culture of collaboration is supported by various automation tools and practices such as Continuous Integration (CI), Continuous Deployment (CD), Infrastructure as Code (IaC), and automated testing.
Supporting Reference:
Juniper Networks Automation and DevOps Documentation: This documentation emphasizes the importance of collaboration between development and operations teams to streamline processes and improve efficiency, aligning perfectly with the principles of DevOps.
"The DevOps Handbook" by Gene Kim, Patrick Debois, John Willis, and Jez Humble: This book provides an in-depth look into how DevOps practices enhance collaboration and lead to faster, more reliable software delivery.
IEEE and Industry Standards: While DevOps practices are widely adopted, they are not defined or maintained by IEEE or any other formal standards body, which is why option D is incorrect.

NEW QUESTION # 46
Prior to creating a Junos automation script, you want to understand the output format of a new isolated RPC calls to use in the script.
What is the provided on Junos devices to help accomplish this task?

A. PyEZ
B. RPC on Demand
C. NETCONF
D. REST API Explorer

Answer: D

NEW QUESTION # 47
Which two tools would you use to make REST API requests? (Choose two.)

A. cURL
B. NETCOfJF
C. Web browser
D. SSH

Answer: A,C

Explanation:
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 References:
* 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.
