Arista ACE Specialist - Data Center study guide
Arista ACE Specialist - Data Center · Work through your exam, one topic at a time.
The Arista ACE Specialist - Data Center is a vendor credential for network engineers who design, build, and operate Arista-based data center fabrics. It is aimed at practitioners with hands-on exposure to leaf-spine architectures, Arista's Extensible Operating System (EOS), and the CloudVision management platform, rather than at candidates seeking a general networking certification. The exam is organized into four equally weighted domains: Data Center Networking Fundamentals; Arista EOS Configuration and Operations; CloudVision and Network Automation; and Data Center Design, Routing, and Troubleshooting. Each domain carries roughly a quarter of the content, so no single topic can be skipped without risking the overall result. Topics on this exam: Data Center Networking Fundamentals, Arista EOS Configuration and Operations, CloudVision and Network Automation, and Data Center Design, Routing, and Troubleshooting. The Arista ACE Specialist - Data Center study guide has 4 sections and about 1,057 words.
01Data Center Networking Fundamentals
A data center fabric is judged by predictable latency, high bisection bandwidth, and fast failure convergence. Understand the two dominant architectures: the classic three-tier (core/aggregation/access with STP) and the spine-leaf Clos fabric, where every leaf connects to every spine and no leaf-to-leaf links exist.
265 words, about 1 min02Arista EOS Configuration and Operations
EOS is a single-image, Linux-based network OS with a SysDB architecture and a consistent CLI across platforms. Know the operational modes: enable, configure, and interface/config submodes.
279 words, about 1 min03CloudVision and Network Automation
CloudVision is Arista's management and telemetry platform. Understand its components: the CloudVision portal (CVP) for configuration management and change control, and CloudVision as a telemetry/analytics layer using gNMI/gRPC streaming.
233 words, about 1 min04Data Center Design, Routing, and Troubleshooting
Design starts with requirements: bandwidth, oversubscription, failure domains, and scale. Know how to size a spine-leaf fabric (spine count for bandwidth, leaf count for ports, ECMP paths = number of spines).
