The 350-901 exam is the official test behind the Cisco Certified DevNet Professional certification, a Professional-level credential from Cisco. Passing it validates the skills measured by the Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) objectives and proves to employers that you can apply those skills in real-world scenarios, not just recite theory. The credential also sits alongside related certifications such as Cisco Certified DevNet Associate (DEVASC 200-901), Cisco Certified DevNet Professional, making it a strong building block in a broader Cisco certification path. For candidates planning a longer-term career move, the 350-901 exam is often the step that turns study effort into a verifiable, resumé-ready qualification.

The Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) blueprint is divided into 4 exam domains. The first three are Cisco Platforms (50%), Application Deployment and Security (10%), and Understanding and Using APIs (20%). The weightings matter: they tell you where the bulk of your score comes from, so allocate study time in proportion rather than spreading it evenly. Scroll back to the exam topics section above for the complete domain-by-domain breakdown of the 350-901 exam.

The Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) exam gives you 120 minutes to work through 55-65 questions. Do the math before test day: divide the total time by the question count to set a steady per-question pace, and treat that number as a hard budget rather than a guideline. When a question eats more than its share, flag it and move on — a flagged question can be revisited, but lost minutes can't. Running two or three full timed mock exams in the Actual4Labs test engine before your exam date is the most reliable way to make that pacing automatic.

According to Cisco, the Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) exam uses the following question formats: Multiple choice, Multiple answer, Drag and drop, Simulation-based questions. Different formats reward different habits. For scenario-based items, read the final sentence of the question stem first so you know what's actually being asked before you dig into the details, and never change an answer unless you can point to the exact clue you missed. The Actual4Labs question bank lets you rehearse every format until each one feels routine.

The credential you earn by passing the Cisco Developing Applications using Cisco Core Platforms and APIs (DEVCOR) exam remains valid for 3 years.
