Juniper Exam Updates 2025: Retirements and New Exam Releases

Juniper Networks continues to update its certification program to align with the rapid evolution of networking, security, and automation. In 2025, several key exams have either been retired or are scheduled to be retired, with new versions introduced to reflect the latest features, technologies, and industry best practices. For professionals pursuing Juniper certifications, these changes are important to note, as they directly affect study plans and certification paths. Let’s explore the updates in detail.

JN0-231 Retired, JN0-232 Introduced

Retired Exam: JN0-231
Retirement Date: August 3, 2025
Replacement Exam: JN0-232

The JN0-231 exam, part of the Juniper Networks Certified Associate – Security (JNCIA-SEC) certification, was officially retired on August 3, 2025. This entry-level certification verifies a candidate’s understanding of Junos OS for SRX Series devices and the fundamentals of network security.

Its successor, the JN0-232 exam, builds on the same foundation but includes updated objectives. Networking professionals can expect the new exam to place more emphasis on current cybersecurity challenges, next-generation firewall capabilities, and modern configuration practices. This ensures that certified individuals have skills relevant to today’s threat landscape and security operations.

The JN0-232 exam continues to serve as a great starting point for IT professionals beginning their journey in Juniper security certifications.

JN0-335 Retired, JN0-336 Introduced

Retired Exam: JN0-335
Retirement Date: September 1, 2025
Replacement Exam: JN0-336

On September 1, 2025, Juniper retired the JN0-335 exam, which was part of the Juniper Networks Certified Specialist – Security (JNCIS-SEC) certification. This certification is designed for networking professionals with an intermediate level of knowledge in Junos OS and SRX Series devices.

The replacement, JN0-336, continues to validate candidates’ ability to configure, implement, and troubleshoot Junos-based security platforms. However, the updated exam includes newer topics, reflecting evolving threats, advanced firewall technologies, intrusion prevention, and the integration of security policies into complex environments.

For IT professionals aiming to advance beyond the associate level, the JN0-336 is now the required exam to achieve the JNCIS-SEC certification. It provides recognition of deeper skills and prepares candidates for more advanced Juniper certifications in security.

JN0-422 Scheduled Retirement, JN0-423 Coming Soon

Exam Scheduled for Retirement: JN0-422
Retirement Date: October 5, 2025
Replacement Exam: JN0-423

The JN0-422 exam, part of the Juniper Networks Certified Specialist – Automation and DevOps (JNCIS-DevOps) track, is scheduled to retire on October 5, 2025. This exam has been a critical step for professionals looking to demonstrate their ability in automation frameworks, scripting, and network programmability.

Its successor, the JN0-423, will bring updated exam objectives, reflecting the fast-changing DevOps and automation landscape. Candidates can expect the new exam to focus on platform automation, the use of modern APIs (NETCONF, RESTCONF, and others), Python scripting, data serialization, and infrastructure-as-code practices.

This update ensures that Juniper-certified DevOps professionals have the practical skills needed to work with automation tools in modern cloud and network environments.

What These Changes Mean for Candidates

If you are currently pursuing a Juniper certification in security or DevOps, these updates directly impact your preparation strategy:

For JN0-231 candidates: If you did not take the exam before August 3, 2025, you must now prepare for JN0-232.
For JN0-335 candidates: The deadline has passed, and JN0-336 is now the only option moving forward.
For JN0-422 candidates: You have until October 5, 2025, to take the current version. After this date, you must prepare for JN0-423.

By aligning your study efforts with these updated exams, you ensure your certification journey remains valid and recognized in the industry.

Juniper’s 2025 exam updates highlight the company’s commitment to maintaining a relevant and industry-aligned certification program. With JN0-231 and JN0-335 already retired, and JN0-422 approaching retirement, networking professionals should carefully plan their certification paths and transition smoothly to the new exams (JN0-232, JN0-336, and JN0-423).

For candidates, staying informed and preparing for the updated exam objectives is key to success. These changes not only keep certifications aligned with modern technologies but also enhance the value of a Juniper credential in today’s competitive IT landscape.
