Free ACE-A1.2: Arista Certified Engineering Associate Exam Questions and Answers
Arista Certified Engineering Associate is part of the Arista Certified Engineer (ACE) programme from Arista Networks. Arista does not use multiple choice. Every ACE exam is a remote, performance-based lab in which you configure real EOS devices: two hours at Associate level and four hours at Specialist, Professional and Expert. Arista publishes no question count, no pass mark and no standalone exam fee. Certifications last two years, and since the programme was restructured on 1 June 2025 renewing one credential extends the same or lower tiers across the other tracks rather than each having to be renewed on its own.
The first 10 questions on this page are free to read, answers included — no account and no card. A plan opens the rest of the bank, the full timed practice test and your weak-topic reporting.
