CNPLE case studies

The Certified Network Professional Engineer (CNPE, sometimes written CNPLE) is a vendor-neutral credential intended for network engineers who design, operate, secure, and troubleshoot production networks rather than only configure single devices. It suits candidates with a few years of hands-on experience who are moving from task execution toward architecture ownership, or who need a structured way to demonstrate breadth across routing, security, operations, services, and automation. The exam blueprint spans seven domains: network architecture and design, routing and switching, network security, network operations and troubleshooting, network services and applications, network automation and programmability, and governance, compliance, and professional practice. Expect scenario-based multiple-choice and multiple-response items that test judgment, not recall of trivia: given a topology description, a symptom set, or a constraint list, you choose the defensible design or the next diagnostic step. The CNPLE case studies are 5 cases and about 3,084 words.
