FREQUENTLY ASKED QUESTIONS
Q1. I currently hold Arista Certified Engineer (ACE) L3 Cloud Journey man. Willl this automatically converted to a new Arista Certification?
Your ACE L3 will be convereted to a new certification Arista Certified Engineer (ACE) Data Center Specialist as the old courses and certification were more focused on Data Center technologies.
Q2. How do you earn an ACE Professional Level certification (ACE-Level 5)
You must pass both the Operations Specialist exam and the Engineering Specialist exam within the same track (e.g., Data Center, Campus, Routing, Automation). Once both are completed, the Level 5 Professional certification is automatically awarded—there is no separate exam.
Q2. Can I enter the ACE program at a higher level?
Yes. Arista lets you attempt Specialist or higher-level exams aligned with your experience. However, those exams will test knowledge from the foundational levels upward
