Juniper Automation and DevOps, Associate (JNCIA-DevOps) Sample Questions (Q13-Q18):NEW QUESTION # 13
You want to make a list in Python to store data.
Which statement is the correct way to accomplish this task?
  • A. L = {0, 1, 2, 3, 4, 5}
  • B. L = "0, 1, 2, 3, 4, 5"
  • C. L = (0, 1, 2, 3, 4, 5)
  • D. L = [0, 1, 2, 3, 4, 5]
Answer: D
Explanation:
In Python, to create a list, you use square brackets []. The correct syntax to create a list containing the numbers 0 through 5 is:
L = [0, 1, 2, 3, 4, 5]
This statement creates a list object that stores the specified integers.
Other options are incorrect:
A defines a string, not a list.
B defines a set, which is an unordered collection with no duplicate elements.
D defines a tuple, which is an immutable sequence, not a list.
Reference:
Python Official Documentation: Discusses lists, sets, tuples, and their syntaxes.
Python Data Structures Guide: Provides examples of creating and manipulating lists.

NEW QUESTION # 14
YAML uses which two data structures? (Choose two.)
  • A. objects
  • B. mappings
  • C. arrays
  • D. sequences
Answer: B,D
Explanation:
YAML (YAML Ain't Markup Language) primarily uses two data structures:
Mappings: These are key-value pairs, similar to dictionaries or hashes in programming languages. In YAML, mappings are used to represent associative arrays or objects. They are defined with a colon ( separating the key from the value.
Example:
key: value
name: John Doe
Sequences: These are ordered lists of items, equivalent to arrays or lists in other programming languages. Sequences in YAML are denoted by a dash (-) followed by a space and then the item.
Example:
fruits:
- Apple
- Banana
- Cherry
Detailed Explanation:
Mappings (B) allow you to define relationships between keys and values, making it possible to represent more complex data structures like dictionaries or objects.
Sequences (C) allow you to represent ordered collections, which is important for listing elements that must maintain a specific order.
YAML is often used in configuration files and data serialization in DevOps environments, such as in Ansible playbooks, Kubernetes manifest files, and CI/CD pipeline definitions. Its simplicity and human-readable format make it a popular choice for these applications.
Reference:
YAML Official Documentation: YAML's specification outlines these core data structures.
Juniper Automation and DevOps Documentation: Provides best practices for using YAML in network automation scripts and configuration management.

NEW QUESTION # 15
What are two important aspects of the DevOps culture? (Choose two.)
  • A. separation of duties
  • B. people
  • C. communication
  • D. use of specific tools
Answer: B,C
Explanation:
Two important aspects of the DevOps culture are:
Communication (A): In a DevOps environment, continuous and effective communication between development, operations, and other stakeholders is crucial. It ensures that everyone is aligned, reduces misunderstandings, and facilitates faster and more efficient workflows.
People (D): DevOps is as much about the people as it is about the processes and tools. The culture emphasizes collaboration, shared responsibility, and a mindset focused on continuous improvement. Empowering people to work together across different disciplines is at the heart of DevOps.
Options B and C are not primary aspects of the DevOps culture. While tools are essential in implementing DevOps practices, the culture emphasizes communication and collaboration among people more than the use of specific tools or rigid separation of duties.
Reference:
DevOps Handbook: Discusses the cultural aspects of DevOps, with a focus on communication and people.
DevOps Best Practices: Highlights the importance of fostering a culture that prioritizes collaboration and shared goals.

NEW QUESTION # 16
Using the set rest control configuration command, what are two ways to control access to the REST API running on a Junos device? (Choose two.)
  • A. Limit management access to only SSH
  • B. Limit access to only certain source IP addresses
  • C. Limit the number of simultaneous connections.
  • D. Limit management access to specific users.
Answer: B,C
Explanation:
When using the set rest control configuration command on a Junos device, you have several options to control access to the REST API. Two effective methods include:
Limiting the number of simultaneous connections: This ensures that the REST API is not overwhelmed by too many concurrent requests, which could potentially lead to performance issues or denial of service.
Limiting access to certain source IP addresses: This method restricts API access to specific IP addresses, enhancing security by ensuring that only trusted sources can interact with the REST API.
Option A (Limit management access to only SSH) is unrelated to controlling REST API access specifically.
Option B (Limit management access to specific users) might be relevant in a different context, but it is not directly tied to REST API control via the specific command mentioned.
Supporting Reference:
Juniper Networks REST API Documentation: This documentation explains how to configure and control access to the REST API on Junos devices, including connection limits and IP-based access control.

NEW QUESTION # 17
What is the default port for NETCONF connections over SSH?
  • A. 0
  • B. 1
  • C. 2
  • D. 3
Answer: B
Explanation:
