Arista Foundations study plan

Describe how EOS separates control-plane, data-plane, and management-plane functions

Diagram the boot process from power-on through full EOS startup and identify where configuration is applied

List the major EOS daemons and state the role each plays in forwarding and management

Configure basic management access (user accounts, SSH, management interface addressing) on a simulated EOS device

Compare underlay and overlay networking concepts and explain why each exists in a cloud data center

Explain VXLAN encapsulation and the role of the tunnel endpoint in extending Layer 2 over Layer 3

Differentiate EVPN control-plane learning from flood-and-learn VXLAN behavior

Configure a basic VXLAN tunnel between two simulated switches and verify the tunnel comes up

Draw a two-tier leaf-spine topology and label spine, leaf, and host attachment points

Explain equal-cost multipathing and why leaf-spine topologies provide predictable east-west latency

Compare Layer 2 versus Layer 3 leaf-spine designs and state a tradeoff for each

Configure an underlay routing protocol across a simulated leaf-spine fabric and confirm full reachability

Describe how MLAG provides redundant dual-homed host connectivity and identify its failure modes

Explain multi-homing options for hosts and servers in a leaf-spine fabric

Configure MLAG between a pair of simulated leaf switches and verify the peer link and active member state

Test a single-link failure in the simulated fabric and record the observed convergence behavior

Describe the CloudVision architecture and the roles of its major components

Explain the difference between configuration management and telemetry-driven visibility in CloudVision

Outline the workflow for onboarding a device into CloudVision and pushing a change

Map a sample configuration change to the CloudVision change-control and rollback process

Identify the telemetry streams CloudVision collects and what each reveals about fabric health

Interpret a sample alert or anomaly and trace it back to a probable root cause

Describe the role of streaming telemetry versus polling for observability at scale

Draft a monitoring plan that states which signals you would watch and what threshold triggers action

Compare static routing, OSPF, and BGP and state when each is appropriate in a data center fabric

Explain BGP route selection criteria and apply them to a sample multi-path scenario

Describe common data center security controls and where they are enforced in a leaf-spine fabric

Configure route filtering or an access control policy on a simulated device and verify the intended traffic is blocked

Re-derive the key facts from each domain without notes and flag any gaps

Re-run the two most complex labs from earlier weeks end to end

Answer a timed set of practice questions across all four domains and review every miss

Write a personal weak-area list with a remediation action for each item
