CCDE practice questions - frequently asked questions

Plain answers about how CCDE Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real CCDE exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The CCDE exam spans 5 domains: Business Strategy Design (15% of the exam); Control, Data, Management Plane, and Operational Design (25% of the exam); Network Design (30% of the exam); Service Design (15% of the exam); Security Design (15% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Network Design 30%; Control, Data, Management Plane, and Operational Design 25%; Business Strategy Design 15%; Service Design 15%; Security Design 15%.

The CCDE exam has 110 questions and is completed in 2 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
