Cisco DCAUTO 300-635 study plan

Cisco DCAUTO 300-635 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Data Center Automation and Programmability Fundamentals & Cisco ACI and NX-OS Automation with APIs and Scripting

  • Map the 300-635 blueprint into a personal checklist that tags every objective to a domain and a hands-on artifact

  • Explain the difference between imperative CLI automation, model-driven programmability (NETCONF/RESTCONF/gNMI), and controller-based intent to a colleague in under five minutes

  • Stand up a local lab with Nexus 9000v or ACI simulator plus a Python virtual environment and Postman

  • Write and run a first Python script that authenticates to an NX-OS device over REST and retrieves interface counters

Your checkpoint

A one-page blueprint checklist plus a working Python script and Postman collection that authenticate to the lab and pull interface state

Week 2

Data Center Automation and Programmability Fundamentals & Cisco ACI and NX-OS Automation with APIs and Scripting

  • Compare YANG models, OpenConfig versus native models, and identify which payloads a given NX-OS feature exposes

  • Perform NETCONF get-config and edit-config operations against the lab and capture the request/response pairs

  • Distinguish REST API authentication methods (basic, token, cookie) and implement token refresh in a script

  • Describe data center automation drivers and where Ansible, Terraform, and controllers each fit

Your checkpoint

A lab notebook with annotated NETCONF and REST request/response captures for at least three distinct NX-OS operations

Week 3

Cisco ACI and NX-OS Automation with APIs and Scripting & Cisco Nexus Dashboard and Data Center Network Management Automation

  • Automate VLAN and interface configuration on NX-OS using both the NX-API CLI and NX-API REST interfaces

  • Implement idempotent configuration logic that reads current state before pushing changes

  • Explore Cisco Nexus Dashboard APIs for site inventory and fabric health retrieval

  • Configure role-based access and least-privilege credentials for automation accounts in the lab

Your checkpoint

A Python module that idempotently provisions VLANs and access ports across two lab switches and logs before/after state

Week 4

Cisco Nexus Dashboard and Data Center Network Management Automation & Data Center Automation and Programmability Fundamentals

  • Enumerate the Nexus Dashboard services (Insights, Orchestrator, Fabric Controller) and state what each automates

  • Retrieve and interpret fabric health, anomalies, and assurance data through Nexus Dashboard APIs

  • Explain the role of the Nexus Dashboard in multi-site and NDFC-managed fabrics

  • Trace a configuration change from API call to device-level result

Your checkpoint

A written walkthrough of one end-to-end Nexus Dashboard API workflow with screenshots of returned JSON and an interpretation of each field

Week 5

Infrastructure as Code and Configuration Management (Ansible, Terraform, CI/CD) & Cisco ACI and NX-OS Automation with APIs and Scripting

  • Build an Ansible inventory and playbook that configures NX-OS devices using network-specific modules

  • Implement a Terraform workflow that provisions infrastructure and manages provider state safely

  • Use idempotency checks and dry-run modes to validate changes before applying them

  • Store secrets and credentials outside playbooks and repositories

Your checkpoint

A Git repository containing an Ansible role and a Terraform configuration that both target the lab, with a README documenting variables and secret handling

Week 6

Infrastructure as Code and Configuration Management (Ansible, Terraform, CI/CD) & Cisco Nexus Dashboard and Data Center Network Management Automation

  • Design a CI/CD pipeline that lints, validates, and deploys network configuration changes

  • Add automated tests and config diff gates that block non-compliant changes

  • Integrate a configuration source of truth with the pipeline

  • Define rollback and approval steps for failed deployments

Your checkpoint

A working CI pipeline (GitHub Actions or GitLab CI) that runs lint, validation, and a simulated deployment against the lab with a passing and a deliberately failing run captured

Week 7

Cisco ACI and NX-OS Automation with APIs and Scripting & Infrastructure as Code and Configuration Management (Ansible, Terraform, CI/CD)

  • Automate ACI tenant, AP, EPG, and contract creation through the ACI REST API

  • Use ACI object model conventions (DN, class, RN) to query and modify objects programmatically

  • Apply an Infrastructure-as-Code pattern to ACI policy so tenants are reproducible from a repository

  • Compare ACI and NX-OS automation approaches and choose appropriately for a scenario

Your checkpoint

A script or Terraform configuration that builds a complete tenant with EPGs and contracts from a declarative input file, verified in the ACI simulator

Week 8

Data Center Automation and Programmability Fundamentals & Cisco Nexus Dashboard and Data Center Network Management Automation & Infrastructure as Code and Configuration Management (Ansible, Terraform, CI/CD) & Cisco ACI and NX-OS Automation with APIs and Scripting

  • Re-run every blueprint checklist item and mark gaps with a remediation action

  • Complete timed practice questions across all four domains and analyze misses by domain

  • Rebuild one deliverable from scratch without notes to confirm retention

  • Write a final weak-area list with a post-exam learning plan

Your checkpoint

A scored practice exam log by domain plus a one-page gap analysis with remediation actions

Milestones

Week 2: Can independently authenticate to a lab device and perform a NETCONF edit-config and a REST API call without referring to notes

Week 4: Can explain Nexus Dashboard services and complete a Nexus Dashboard API workflow end to end, scoring 70 percent or higher on a self-made domain 1 and 2 quiz

Week 6: Has a CI pipeline in version control that lints, validates, and simulates deployment, with evidence of both a passing and a failing run

Week 8: Scores 80 percent or higher on a full timed practice set, with no domain below 70 percent, and has a documented gap list
