EXIN CDCE study plan

Map the four exam domains to your current knowledge and record a baseline confidence score (1-5) for each of the 25% weightings

Define the data centre design vocabulary you must command: availability, redundancy, concurrent maintainability, fault tolerance, and Tier/Class distinctions

Sketch the standard functional areas of a data centre (white space, grey space, entrance room, telecom room, electrical room, UPS room, generator yard) from memory and label the boundaries between them

Explain to a colleague, in under five minutes, why N+1 and 2N differ in both cost and maintainability outcome

Compare four topologies (single path, N+1, 2N, 2(N+1)) on component count, single points of failure, and concurrent maintainability

Calculate the electrical capacity chain from utility feed through transformer, UPS, PDU, and rack, identifying where derating factors apply

Size a cooling approach for a given room by matching kW of IT load to air-cooled, chilled-water, or in-row options

Identify the fire detection and suppression choices appropriate to an occupied white space and justify each

Draw the power and cooling paths for one topology and mark every point where a single failure would take down the IT load

Convert the week 2 design into an operational commissioning checklist covering electrical, mechanical, and security systems

Sequence the handover activities from construction completion through integrated systems testing to operational acceptance

List the routine maintenance tasks for UPS batteries, generators, chillers, and CRAC/CRAH units with typical intervals

Draft a change management procedure for a live white space that protects availability during maintenance windows

Build a monitoring dashboard specification listing the metrics that matter: temperature at rack inlet, humidity, power load per phase, PUE, and UPS battery health

Define incident severity levels and the escalation path from a first alert to facilities and IT stakeholders

Write the procedure for a planned generator load test and the rollback steps if the test fails

Explain how capacity records (space, power, cooling, network ports) are kept current and who owns each record

Distinguish the roles of standards bodies and frameworks relevant to data centres (ISO/IEC, TIA, Uptime Institute, EN 50600, BICSI) without conflating certification with design guidance

Map each compliance requirement you have studied to the design or operational control that satisfies it

Interpret an SLA and an availability target, and state how measurement windows and exclusions change the reported figure

Identify the audit evidence a data centre would need to produce for power, environmental, and access control records

Draft a risk register for a mid-size facility with likelihood, impact, owner, and mitigation for each entry

Compare build, lease, and colocation options on total cost of ownership, control, and time to market

Construct a simple business case for a resilience upgrade that quantifies downtime cost against capital spend

Explain how sustainability reporting (PUE, WUE, renewable sourcing) feeds into management decisions

Draft a staffing model for 24x7 coverage that accounts for shift patterns, on-call rotation, and required competencies

Design a training and competence-assessment plan for facilities technicians and shift leads

Define vendor management controls: SLA review cadence, performance scorecards, and escalation triggers

Prepare a one-page executive summary of a data centre strategy that a non-technical board member could act on

Re-score your confidence per domain and target the two weakest areas with focused review

Answer timed practice questions across all four domains and log every miss by domain and root cause

Re-derive the four topologies and the compliance cross-reference from memory without notes

Write a personal exam-day plan covering time allocation per domain and a strategy for ambiguous scenario questions
