BICSI DCDC · Work through your exam, one topic at a time.
The BICSI Data Center Design Consultant (DCDC) credential appears in this profile as a data center design qualification administered by BICSI, the industry association behind the Registered Communications Designer (RCDD) and other certifications. Candidates should treat the six-domain structure shown here as a provisional working outline rather than confirmed exam content, because the official DCDC credential and exam pages returned HTTP 404 errors when retrieved on 2026-11-02. The BICSI DCDC study guide has 6 sections and about 1,783 words.
01Data Center Design and Project Requirements
Every defensible design begins with a requirements document that captures availability target, IT load forecast, growth horizon, redundancy philosophy, and budget. Candidates must know the four classic availability tiers (often mapped to Tier I–IV) and what each adds: non-redundant capacity, redundant components, concurrently maintainable paths, and fault-tolerant paths.
319 words, about 2 min02Data Center Site and Space Planning
Site planning balances natural hazard exposure, utility availability, connectivity options, latency to users, physical security, and expansion potential. Candidates should understand floodplain and seismic risk, proximity to fuel and power infrastructure, and fiber route diversity.
329 words, about 2 min03Data Center Power and Electrical Systems
Trace the full electrical chain: utility service, transformers, switchgear, automatic transfer switches (ATS), uninterruptible power supplies (UPS), power distribution units (PDU), remote power panels, and rack PDUs. Understand where redundancy is applied and how a failure propagates.
307 words, about 2 min04Data Center Cooling and Mechanical Systems
Cooling design starts with heat load: IT equipment, lighting, people, and envelope gains. Understand sensible vs.
292 words, about 1 min05Data Center Cabling and Telecommunications Infrastructure
Understand the hierarchical cabling model: entrance facility, main distribution area (MDA), horizontal distribution area (HDA), zone distribution area (ZDA), and equipment distribution area (EDA). Know how these map to cross-connects and how redundancy (diverse paths, dual homing) is achieved.
253 words, about 1 min06Data Center Operations, Security, and Commissioning
Operations covers change management, capacity management, preventive maintenance, and incident response. Candidates should understand the difference between planned and unplanned work, the role of a change advisory process, and how maintenance windows preserve availability.
