The 350-901 exam is Cisco's official assessment for the Cisco Certified DevNet Professional certification, positioned at the Professional level. It measures whether you can apply the Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) skills in practical, job-like situations — which is why rote memorization alone rarely gets candidates across the line. The credential fits into a wider Cisco certification path that includes Cisco Certified DevNet Professional, Cisco Certified DevNet Specialist - Core, so passing it opens more than one door. Think of the 350-901 exam as the point where your preparation becomes a qualification employers can verify.

The Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) syllabus is organized into 5 domains, beginning with Software Development and Design (20%), Using APIs (20%), and Application Deployment and Security (20%). Those percentages are your study budget: a domain carrying a larger share of the score deserves a matching share of your hours. The full domain-by-domain breakdown is in the exam topics section above — work from that, not from habit.

You'll have 120 minutes to complete 90-110 questions on the Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) exam. Before test day, convert those numbers into a per-question time budget — then defend it. When a single question starts eating double its share, mark it, move on, and return with whatever time remains. Two or three full timed runs in the Lead1Pass test engine will make that discipline automatic; its built-in timer records every attempt so you can watch your pace improve session by session.

Cisco sets the passing bar at Variable (750-850 / 1000), and a seat at the 350-901 exam costs $400 USD. There is no reduced fee for a second try — a miss means paying the full amount again — so the cheapest retake is the one you never need. A sensible approach: run timed self-assessments with Lead1Pass practice tests until your scores sit comfortably above the passing mark with margin to spare, then book your exam date. That cushion absorbs nerves and the inevitable oddball question.

Cisco lists the Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) question formats as: Multiple-choice, Multiple-response, Drag-and-drop, Simulation. Each format has its own trap. With scenario items, the actual question hides at the end of a long stem — read the last sentence first, then work back through the details. With elimination-friendly formats, cross out what you can disprove before committing. The Lead1Pass question bank lets you rehearse every format until the mechanics feel boring, which is exactly where you want to be on exam day.
