Arista ACE-S Automation (Foundations) study guide
Arista ACE-S Automation (Foundations) · Work through your exam, one topic at a time.
The Arista Certified Engineer – Specialist (Automation) credential, commonly abbreviated ACE-S, is positioned as a specialist-level certification focused on network automation within Arista environments. This study page is an independent preparation resource for candidates planning to sit the ACE-S Automation (Foundations) exam; it is not affiliated with, endorsed by, or sponsored by Arista, and it does not reproduce any official exam content. The profile organizes preparation around four equally weighted domains: EOS and CloudVision fundamentals, automation and programmability tooling, CloudVision automation and provisioning workflows, and network telemetry, monitoring, and observability. Each domain carries a 25 percent share of the blueprint, so candidates should expect broad coverage rather than deep specialization in any single area. Topics on this exam: Arista EOS and CloudVision Fundamentals, Automation and Programmability Tooling, CloudVision Automation and Provisioning Workflows, and Network Telemetry, Monitoring, and Observability. The Arista ACE-S Automation (Foundations) study guide has 4 sections and about 1,316 words.
01Arista EOS and CloudVision Fundamentals
Arista EOS is a single-binary, Linux-hosted network operating system. Because it runs on standard Linux, EOS exposes Sysdb (a state database that is the source of truth for running configuration and operational state), a full bash shell, and open APIs.
364 words, about 2 min02Automation and Programmability Tooling
Arista's programmability stack has several layers, and questions test whether you know which tool solves which problem. eAPI - JSON-RPC over HTTP(S) to EOS.
295 words, about 1 min03CloudVision Automation and Provisioning Workflows
CloudVision provisioning follows a consistent sequence that questions will test out of order: 1. Onboard the device - the device must be reachable and running TerminAttr, authenticated to the CloudVision cluster.
335 words, about 2 min04Network Telemetry, Monitoring, and Observability
Arista's observability model is push-based. TerminAttr runs on the switch and streams state to CloudVision (or to a gNMI collector).
