The Juniper JNCIA-Junos certification is an introductory certification focusing on the basics of the Junos operating system and the basic configuration of Juniper devices.

1. Introduction to the Juniper JNCIA-Junos certification

Juniper JNCIA Junos (JN0-105) is an entry-level core certification for network technology launched by Juniper Networks, focusing on verifying practitioners' basic understanding of the Juniper Junos operating system, basic configuration of Juniper network devices, application of network basic protocols, and practical abilities in simple troubleshooting.

JN0-105 is the cornerstone of Juniper's certification system, aimed at cultivating professional talents who can independently complete the deployment and daily operation of small and medium-sized network infrastructure. It is the core entry credential for entering the Juniper ecosystem and engaging in network technology positions.

Juniper network devices are widely used in enterprise networks, operator backbone networks, and other scenarios, and the Junos operating system is its unified core management platform. The core positioning of JNCIA Junos certification is to cultivate "Juniper equipment practical basic operation and configuration personnel," rather than simply theoretical learners.

The certificate holder needs to be proficient in the core operations and basic network protocols of the Junos system, able to complete the initialization configuration of Juniper devices, network interface and routing deployment, basic security policy configuration, solve common network failures, and ensure network connectivity and stability for small and medium-sized network needs.

When building a basic network for small businesses, JNCIA Junos certified personnel will complete VLAN partitioning and port configuration for Juniper EX switches, achieving internal network isolation for different departments; Configure static routing or OSPF dynamic routing of MX router to realize the connection between enterprise intranet and Internet; The basic security policy is configured through the SRX firewall to allow legitimate intranet traffic to access the Internet, block illegal external access, and ensure basic network security.

2. The Rewards of Being a Juniper JNCIA Junos (JN0-105)

JNCIA Junos is an officially recognized entry-level qualification by Juniper, with a high degree of recognition among Juniper partners. When recruiting for junior network operation and maintenance positions, they are often listed as a "priority condition." It is difficult for uncertified candidates to pass the resume screening process, especially in scenarios where Juniper devices are widely used, where their advantages are significant. Internationally, the hourly wage of certified individuals is 10%-15% higher than that of uncertified individuals, which is a "bonus point" for beginners in network technology.

JNCIA Junos is the starting point of Juniper's certification system. After passing, one can seamlessly advance to JNCIP and JNCIE certifications, gradually growing into a Juniper network expert with a clear career development path.

JNCIA Junos certification covers the basic and practical configuration of the Junos system, proving the basic ability to independently operate Juniper equipment. Enterprises can directly arrange for certified personnel to participate in basic network projects without extensive pre job training, and they can quickly get started with work after joining.

3. Core Components of the Juniper JNCIA Junos (JN0-105) Certification

For practitioners who are committed to becoming network engineers and hope to master enterprise level network equipment operation and maintenance skills, Juniper Junos operating system and basic network technology certification is a highly valuable entry-level professional qualification.

Juniper Junos certification focuses on the full process operation of the core operating system and basic network technology of Juniper network devices, aiming to comprehensively verify whether you have the complete knowledge system and practical ability required to configure, manage, and maintain Junos based network devices.

As the starting point of all work, Junos operating system fundamentals and system management require a deep understanding of the architectural characteristics of the separation of Junos control plane and forwarding plane, proficiency in CLI command line operations, and the ability to complete key system management tasks such as device initialization configuration, software upgrades, and configuration file management.

The foundation of routing technology is the core content of authentication. You need to master the deployment of static and default routes, understand the basic configuration of OSPF dynamic routing protocol, and be able to diagnose and solve network reachability problems by analyzing routing tables.

The foundation of switching technology means that you will learn to configure VLANs, trunk ports, and inter VLAN routing on Juniper EX series switches to achieve network logic isolation and communication, simultaneously mastering the configuration of key switching technologies such as STP/RSTP and link aggregation to ensure the reliability and performance of the switching network.

The Security Fundamentals and Junos Security Policy module introduces basic network security concepts. You need to understand the security zone model of Juniper SRX firewall and be able to configure security policies based on zones and IP addresses, as well as NAT address translation, to achieve basic network access control and service publishing.

Finally, Juniper Junos certification requires you to have daily operational capabilities. You will learn to use Junos' built-in monitoring commands to check device status and be able to locate and resolve common network issues such as interface failures and configuration errors.

4. What are the requirements to be a Juniper JNCIA Junos?

(1) Qualification prerequisites:

Juniper Junos certification does not require mandatory educational qualifications or work experience, and is suitable for beginners and practitioners with zero foundation.

We recommend that you have basic computer network knowledge, simple command line operation experience, and a preliminary understanding of network device configuration to reduce the difficulty of later learning. 

(2) Training and examinations:

JN0-105 has approximately 65 questions, including multiple-choice questions, situational analysis questions, and configuration simulation questions. The exam lasts for 90 minutes. Full score of 1000 points, reaching 650 points or above to pass.

The global unified price for exam fees is $200 (tax fees may vary slightly in different regions)

(3) Qualification maintenance:

The validity period of the JN0-105 certificate is about 3 years, and the renewal requirement is that you need to pass any higher-level certification within the Juniper certification system or retake the current JNCIA Junos exam within the validity period to renew the validity of the certificate.
