Arista ACE-S Campus study guide

Arista ACE-S Campus · Work through your exam, one topic at a time.

The Arista Certified Engineer – Campus (ACE-S Campus) is a professional credential for network engineers who design, deploy, and operate Arista-based campus networks. It suits engineers moving from legacy campus architectures to modern, automated, data-driven campus designs, as well as administrators responsible for wired and wireless campus infrastructure built on Arista platforms. The exam is organized into five equally weighted domains of 20 percent each: Campus Networking Fundamentals; the Arista Extensible Operating System (EOS); CloudVision and Automation; Cognitive Campus Switching Platforms; and Campus Security, Segmentation, and Observability. That balance means candidates cannot pass on switching knowledge alone - EOS operations, CloudVision workflows, campus hardware families, and security and telemetry topics each carry the same weight as fundamentals. The Arista ACE-S Campus study guide has 5 sections and about 1,496 words.

01

Campus Networking Fundamentals

Campus design questions test whether you can reason from traffic flow and failure domains rather than from memorized topologies. Know the classic three-tier model (access, distribution, core) and the collapsed two-tier spine-leaf variant used in modern campuses.

02

Arista Extensible Operating System (EOS)

EOS questions reward knowledge of its architecture and operational model. EOS is a single-image, Linux-based network OS with a modular, state-driven design: protocol agents (Sysdb clients) publish state to the System Database (Sysdb), and other processes subscribe to it rather than talking directly to each other.

03

CloudVision and Automation

CloudVision (CV) is the management and telemetry platform for EOS fleets. Understand its layers: CloudVision Portal (CVP) for configuration management, change control, and compliance; CloudVision as a telemetry and analytics collector; and the CloudVision APIs for programmatic access.

04

Cognitive Campus Switching Platforms

This domain covers Arista's campus switch families and the platform features that distinguish them. Know the positioning: fixed-form access switches for wiring closets, higher-density aggregation switches, and PoE-capable models for endpoints like phones, cameras, and APs.

05

Campus Security, Segmentation, and Observability

This domain ties together access control, traffic isolation, and visibility. Segmentation concepts: VLANs for L2 isolation, VRFs for L3 isolation, and ACLs for policy enforcement at the edge.
