CNPE case studies

The Certified Network Professional Engineer (CNPE) is a vendor-neutral credential aimed at engineers who design, build, secure, and operate production networks rather than simply administer individual devices. It suits mid-career network engineers, senior administrators moving into design roles, and consultants who need to demonstrate breadth across routing and switching, security, operations, WAN and cloud connectivity, automation, and wireless. The exam is delivered as multiple choice and is organised into eight weighted domains: Network Architecture and Design (15%), Routing and Switching (20%), Network Security (15%), Network Operations and Troubleshooting (15%), WAN and Cloud Connectivity (10%), Network Automation and Programmability (10%), Wireless and Mobility (5%), and Network Governance and Professional Practice (10%). Routing and switching carries the largest single share, but the smaller domains decide many results because candidates often skip governance, automation, and cloud topics. The CNPE case studies are 5 cases and about 3,476 words.
