EXIN EPI Certified TIA-942 Internal Auditor study plan

Map the structure of the TIA-942 standard (sections, annexes, normative vs informative content) into a one-page outline you can redraw from memory

Define in your own words the core terminology: data centre, entrance room, main distribution area, horizontal distribution area, equipment distribution area, zone distribution area, backbone and horizontal cabling

Distinguish the four rated levels (Rated-1 through Rated-4) by their redundancy and fault-tolerance characteristics and write a comparison table

Identify which clauses of the standard address topology, cabling, redundancy and environmental separation so you can locate them quickly

Explain each topology element (entrance room, MDA, HDA, EDA, ZDA) and the cabling path that connects them

Classify redundancy concepts (N, N+1, 2N, 2(N+1)) and map each to the corresponding Rated level

Describe the architectural implications of electrical, mechanical and telecommunications redundancy for a given data centre scenario

Compare the four Rated levels on availability, concurrent maintainability and fault tolerance in a written summary

Explain the internal audit function, its independence, objectivity and its place in a governance framework such as the three lines model

Apply the audit programme lifecycle: establishing objectives, scoping, resourcing, risk assessment and annual planning

Draft audit objectives and a scope statement for a TIA-942 internal audit engagement

Identify the risk-based factors that determine audit frequency and priority for data centre audits

Write audit criteria that reference specific TIA-942 requirements rather than vague good practice

Design an audit checklist and sampling approach for a data centre audit, covering both design documentation and physical inspection

Plan audit activities: opening meeting, document review, site walkthrough, interviews and closing meeting

Identify the competencies and independence requirements for an audit team performing a TIA-942 internal audit

Classify evidence types (documentary, physical observation, interview, measurement) and assess their reliability and sufficiency

Apply interview and observation techniques that avoid leading questions and capture verifiable facts

Evaluate evidence against TIA-942 criteria and determine conformity, nonconformity, observation or opportunity for improvement

Structure audit findings using condition, criteria, cause, effect and recommendation

Draft an audit report with executive summary, scope, methodology, findings, conclusions and opinions

Apply quality review and factual accuracy checks to a draft report before issue

Distinguish audit report categories (conformity, nonconformity, observation, opportunity) and choose the right one for each finding

Present findings to management in a closing meeting, handling disagreement constructively

Design a corrective action process with root cause analysis, action owner, target date and verification of effectiveness

Define follow-up criteria and timelines for verifying that corrective actions have been implemented and are effective

Explain how audit results feed into management review and continual improvement cycles

Produce a follow-up tracker and escalation path for overdue corrective actions

Synthesise the standard, topology and audit process knowledge into a consolidated revision map covering all five domains

Complete timed practice questions across all domains and analyse errors by domain and topic

Rehearse explaining Rated levels, audit evidence sufficiency and corrective action verification in short spoken or written answers

Review weak areas identified in practice and close gaps in terminology and criteria
