DCSW case studies

DCSW stands for Data Center Subject Matter Expert Written, a credential aimed at professionals who design, build, operate, or audit mission-critical facilities and need to demonstrate broad, cross-discipline competence rather than narrow vendor or product knowledge. Candidates typically come from electrical or mechanical engineering, facilities operations, ICT infrastructure, commissioning, security, or risk and compliance roles, and are often moving into lead, consultant, or sign-off responsibilities where they must reason about trade-offs across the whole facility. The exam spans eight domains: design and standards, electrical systems and power distribution, mechanical systems and cooling, ICT and network infrastructure, fire protection and life safety, physical security and access control, operations and commissioning, and business continuity, risk and compliance. Expect questions that test judgment, not recall alone: interpreting a scenario, spotting a single-point-of-failure, choosing between redundancy topologies, or explaining why a commissioning sequence exists. The DCSW case studies are 5 cases and about 3,223 words.
