EPI CDCS Study Guide — Certified Data Centre Specialist

Preparing for the EPI CDCS exam (Certified Data Centre Specialist)? This is the complete study guide — six chapters covering all eleven official syllabus modules, written in plain language for working data centre engineers, managers, and consultants who are ready to step up from CDCP.

The real exam: 60 questions in 1.5 hours, multiple-choice, closed-book, with a passing mark of 45 out of 60. It is accredited by EXIN and is the second course in EPI's Design/Build track (CDCP → CDCS → CDCE). You must hold a valid CDCP certificate to register for the CDCS class. The certificate is valid for 3 years, after which recertification is required.

What's inside:

- Chapter 1 — Design Life Cycle and Standards: the data centre design life cycle, and the rating-level landscape — TIA-942, ISO/IEC 22237, EN 50600 and Uptime Tier compared, redundancy options (N, N+1, 2N, 2(N+1)), concurrent maintainability

- Chapter 2 — Building and Raised Floor: location risk, floor and hanging loads with worked examples, fire ratings, blast, ballistic and forced-entry protection, raised-floor installation technique and the mistakes that ruin it, seismic constructions, suspended ceilings

- Chapter 3 — Advanced Power: the formulas you must know, reading single line diagrams, over-current and earth-leakage protection devices and where each belongs, lightning and surge protection, generators and fuel calculations, UPS selection and parallel configurations, battery bank design and testing

- Chapter 4 — EMF and Advanced Cooling: electro magnetic field sources, measurement and shielding calculations, then the full cooling syllabus — psychrometrics and ASHRAE, Delta-T, CFM/CMH and capacity calculations with worked examples, economisers, immersion cooling, CFD, commissioning

- Chapter 5 — Fire Protection and Networking: detection in detail (VESDA, VIEW), why most water-based systems fail data centres, inert and halocarbon gas systems with gas-content calculation, verification of installations — plus TIA-942 cabling topology, ToR vs EoR, fibre loss budgets, labelling

- Chapter 6 — Contamination and Efficiency: noise, contamination classes and control, zinc whiskers — and data centre efficiency: PUE done properly, OCP, cooling and lighting savings

One honest note: EPI does NOT publish percentage weights for the syllabus modules, so no part of this guide claims one module matters more than another. Treat every module as testable, because it is.
