ISQI Big Data - Foundation Level (CDFL) — Questions Candidates Actually Ask
The CDFL exam, officially known as ISQI Big Data - Foundation Level, is the ISQI test that leads to the Big Data - Foundation Level certification at the Foundation level. Passing it validates the skills employers expect from a certified professional.
The CDFL exam contains 40 questions, and you have 60 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.
The passing score for the CDFL exam is 65%, and the official registration fee is Approx. $180–$250 USD / €160–€220 EUR (varies by region). If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.
