ExploreAbout this exam
The ACE Professional credential - the Arista Certified Engineer Professional - is a professional-level certification for network engineers who design, operate, and troubleshoot modern data center and campus networks built on Arista's cloud networking portfolio. It is aimed at practitioners with hands-on experience who want to validate depth beyond entry-level configuration: engineers moving into design roles, consultants scoping cloud and campus migrations, and operators responsible for routing scale, automation, and telemetry-driven visibility. This independent study page organizes preparation around four equally weighted domains: Cloud Networking, Cloud-Grade Routing, Cognitive Campus Workspaces, and Network Observability and Telemetry, each contributing 25 percent of the blueprint. That balance signals what the exam rewards: breadth across data center fabrics, routing architecture, campus and wireless workspaces, and streaming telemetry rather than specialization in a single product family. Preparation should start with the official Arista documentation and solution pages for each domain, especially the Extensible Operating System (EOS) and CloudVision materials, since EOS is described by Arista as the core of its cloud networking solutions and CloudVision as a platform for cloud automation and visibility. Build lab familiarity with fabric design, routing policy, campus segmentation, and telemetry collection, then practice explaining trade-offs aloud. Confirm exam logistics such as question count, duration, passing score, fee, retake rules, and validity directly with Arista or an authorized training partner before scheduling; this page does not state those values and is not affiliated with or endorsed by Arista.
What you'll study
About ACE Professional preparation
How is the ACE Professional exam structured?
The blueprint published here lists four domains at 25 percent each: Cloud Networking, Cloud-Grade Routing, Cognitive Campus Workspaces, and Network Observability and Telemetry. Question count, item types, and time limit are not stated in the available source, so verify the current format with Arista or an authorized training partner before you book a seat.
How difficult is the exam compared with associate-level certifications?
Expect professional-level depth. The even domain weighting means you cannot compensate for weak routing knowledge with strong campus skills. Questions tend to probe design reasoning and operational trade-offs rather than single-command recall, so candidates who only memorize CLI syntax often find the scenario-style items harder than expected.
What should my study order be?
Start with Cloud Networking to anchor leaf-spine and overlay fundamentals, then Cloud-Grade Routing for scale and policy, then Cognitive Campus Workspaces, and finish with Network Observability and Telemetry, which draws on concepts from the other three. Lab each domain before moving on rather than reading all four consecutively.
Which Arista products should I study first?
Begin with the Extensible Operating System (EOS), which Arista describes as the core of its cloud networking solutions for next-generation data centers and cloud networks, and CloudVision, described as a platform for cloud automation and visibility. Then branch into routing platforms such as the 7800R and 7280R series and campus switches such as the 720XP family.
What are common failure modes on this exam?
Three recur often: neglecting telemetry because it feels less central than routing, treating campus wireless as a purely separate topic from fabric design, and studying products in isolation without understanding how EOS, CloudVision, and the underlying hardware interact. Candidates who skip hands-on labs struggle to reason about failure scenarios and scaling limits under time pressure.
How much lab time should I plan for?
Plan for substantial hands-on practice in each of the four domains, not just reading. Build at least one fabric topology, one routing policy exercise, one campus segmentation scenario, and one telemetry collection workflow. The source does not specify a recommended number of hours, so calibrate against your existing experience and weak domains.
What happens if I fail - can I retake it?
Retake policy is not stated in the available source, so it needs verification with Arista or the testing provider. Before retaking, request your score report and identify which of the four domains fell below the passing threshold, then rebuild study time around those domains rather than repeating your entire original plan.
How long is the certification valid?
Validity period is not stated in the available source, so confirm it directly with Arista. Treat recertification as a planning item: track the expiration date as soon as you pass, and note that Arista periodically revises both products and exam blueprints, so recertifying usually means studying current documentation rather than your original notes.
Is this study page officially affiliated with Arista?
No. This is independent study material produced by a third-party platform and is not affiliated with, endorsed by, or sponsored by Arista. Always treat Arista's official documentation, training, and certification pages as authoritative, particularly for exam logistics, pricing, and any blueprint changes announced after this page was published.
