This intensive, hands-on course prepares senior network and cloud engineers to design, implement, secure, operate, and troubleshoot large-scale hybrid network environments. The curriculum is tightly mapped to the CloudNetX (V1) objectives and balances architecture theory, practical CLI/cloud lab work, automation/IaC exercises, observability, and scenario-driven troubleshooting. Learners complete realistic labs (multi-cloud + on-prem emulations), assessed performance tasks, and a capstone network-design plus incident-response project that demonstrates mastery of architecture, zero-trust security, automation, monitoring, and remediation.

Who this course is for (target audience)

Senior network engineers, cloud-network architects, and site/network reliability engineers preparing for advanced hybrid network responsibilities or the CloudNetX (V1) exam. Recommended: multi-year enterprise networking experience and prior exposure to cloud networking and basic automation.

Prerequisite Titles (three)

Professional Experience & Lab Readiness
Senior network/cloud engineering experience, recommended prior certifications, and access to lab/cloud accounts and simulators.

Core Networking & Security Fundamentals
Solid TCP/IP & OSI knowledge; routing & switching (OSPF/BGP/VLANs); hybrid connectivity (VPN/SD-WAN/MPLS); network security and Zero-Trust basics; IAM concepts.

Automation, Observability & Operations
Basic scripting/automation (Bash/Python), Infrastructure as Code (Terraform/CloudFormation), monitoring/observability familiarity, network diagramming, and troubleshooting methodology.

Learning Objectives / Outcomes

After completing this course, learners will be able to:

Design robust hybrid network architectures — produce diagrams and written justifications that satisfy availability, scalability, and security requirements for multi-cloud + on-prem environments.

Configure and validate core routing, switching, and hybrid interconnects — implement and verify OSPF/BGP peering, VLAN segmentation, NAT, VPN/SD-WAN, and cloud interconnect solutions and demonstrate reachability and convergence.

Implement modern network security and Zero-Trust controls — deploy and validate firewalls, microsegmentation, ZTNA/SASE patterns, IAM controls (SSO/MFA/PKI), and wireless security measures.

Automate provisioning and manage IaC safely — author and execute reproducible IaC templates and automation scripts, manage state and idempotency, and implement change/rollback procedures.

Instrument and operate networks with observability — build telemetry pipelines, dashboards and alerts; interpret metrics/logs to identify bottlenecks and meet SLAs.

Troubleshoot and remediate complex hybrid incidents — apply structured troubleshooting, use packet/flow analysis and cloud diagnostics, contain and remediate incidents, and produce an RCA with preventive recommendations.
