Answers Every CDCS Candidate Should Read First
The EXIN EPI Certified Data Centre Specialist exam is the official EXIN test registered under exam code CDCS. Passing it earns you the EXIN EPI Certified Data Centre Specialist certification, a credential at the Advanced / Specialist level. It is also linked to the related certifications: EXIN EPI Certified Data Centre Professional (CDCP), EXIN EPI Certified Data Centre Expert (CDCE). EXIN exams are valued because they test job-ready skills, so a passing score here carries real weight on a resume.
The EXIN EPI Certified Data Centre Specialist exam includes 60 questions to be completed within 90 minutes. Do the pacing math before exam day: with that many items on the clock, you need a steady rhythm and the discipline to flag a hard question and move on instead of stalling. Two or three full timed sessions with the ActualCollection test engine will show you exactly what that pace feels like, so time pressure stops being a factor on the real day.
To pass the EXIN EPI Certified Data Centre Specialist exam you need 75% (45 out of 60), and the official registration fee is USD 320 - 450 (varies by region). A retake is not discounted: a failed attempt means paying the full USD 320 - 450 (varies by region) again, so treat your first sitting as the expensive one. A sensible rule is to book your seat only after you are scoring comfortably above the passing mark on the ActualCollection practice tests, not just squeaking past it once.
