Certified professionals remain in shorter supply than the market wants, which is precisely why this exam keeps showing up in conversations about better roles and better pay.
The Juniper Automation and DevOps, Associate (JNCIA-DevOps) exam gives you 90 minutes to work through 65 questions. That is a tight ratio, and it punishes candidates who get emotionally attached to any single item. The fix is mechanical: answer what you know, flag what you do not, and keep moving. A few full-length timed runs in the Actual4Exams test engine, with its randomized question order, will calibrate your pace far better than untimed reading ever could.
The official fee for Juniper Automation and DevOps, Associate (JNCIA-DevOps) is $200 USD, and Not publicly disclosed (scaled scoring) is what passing takes.
