1. 1Under the TIA-942 certification scheme, what conformity does a licensed certification body verify for a data center?

   1. A.The ANSI/TIA-942 standardCorrect answer: A
   2. B.The ISO 9001 standard
   3. C.The ISO/IEC 27001 standard
   4. D.The ISO 14001 standard

   Explanation: TIA states: "The TIA-942 certification scheme establishes Licensed Certification Bodies (CBs) deemed competent to verify data center conformity with the standard." The body verifies conformity with the standard.

2. 2How does ISO 19011 define an audit programme?

   1. A.Arrangements for one or more audits over a time frame for a purposeCorrect answer: A
   2. B.Description of activities and arrangements for a specific audit
   3. C.Extent and boundaries of the activities covered by an audit
   4. D.Outcome of an audit after considering evidence and objectives

   Explanation: ISO 19011 defines an audit programme as "arrangements for a set of one or more audits (3.1) planned for a specific time frame and directed towards a specific purpose". It organizes one or more audits for a purpose and time frame.

   Reference: ISO 19011:2026 Guidelines for Auditing Management Systems — 3.5 Audit programme

3. 3What role do audit criteria play when evaluating a data center against its chosen TIA-942 rating?

   1. A.They provide the reference for determining conformityCorrect answer: A
   2. B.They replace objective evidence when determining conformity
   3. C.They are the evidence rather than the reference for comparison
   4. D.They are the conformity conclusion rather than its reference

   Explanation: ISO states: "Audit criteria are used as a reference against which conformity is determined." The auditor compares evidence with the applicable criteria to determine conformity.

4. 4In TIA's edge data center guidance, proximity to a river is specifically associated with increased exposure to which site hazard?

   1. A.FloodingCorrect answer: A
   2. B.Seismic shaking
   3. C.Lightning strikes
   4. D.High wind loads

   Explanation: TIA states: "The risk of flooding on EDC should be analyzed depending on the final location. Sites close to rivers, seacoasts, and lakes will be more likely to suffer from this risk." Proximity to a river is a location-dependent flooding exposure.

   Reference: Physical Security Considerations for Edge Data Centers — Environmental Risks, Flooding and Tsunami, p. 3

5. 5An edge data center has low exposure to fire from its surroundings. How should an auditor treat the facility's installed equipment when considering fire exposure?

   1. A.Consider it as a possible internal source of fireCorrect answer: A
   2. B.Exclude it because nearby external fire exposure is low
   3. C.Consider it only if an adjacent building is already burning
   4. D.Consider it only if a forest fire is threatening the site

   Explanation: TIA explains: "Risk of fire on EDC can come from several sources: forests, power lines, buildings, but also it can be generated from the equipment installed inside of EDC." The review should consider both external and internal sources.

   Reference: Physical Security Considerations for Edge Data Centers — Environmental Risks, Fire, p. 3

6. 6How does TIA's TIA-942-C summary treat a battery energy storage system used for standby power?

   1. A.It is one possible standby power technologyCorrect answer: A
   2. B.It is the only acceptable standby power technology
   3. C.It is excluded from the term standby power
   4. D.It replaces the need for a standby power source

   Explanation: TIA describes standby power as "any technology used as standby power, including battery energy storage systems (BESS), natural gas, and hydrogen fuel cells." Battery energy storage is one example.

7. 7Which class is identified in TIA's description of TIA-942-C temperature and humidity guidance for high-density air-cooled equipment?

   1. A.H1Correct answer: A
   2. B.A1
   3. C.A2
   4. D.A3

   Explanation: TIA says: "Temperature and humidity guidelines now align with the 5th addition of ASHRAE TC 9.9 Thermal Guidelines for Data Processing Environments, including the new H1 class for high-density air-cooled equipment." The cited high-density air-cooled class is H1.

8. 8At a closing meeting, how should the audit team present its findings according to EPA's audit guidance?

   1. A.Present findings together with their objective evidenceCorrect answer: A
   2. B.Present conclusions while withholding the supporting observations
   3. C.Present findings as verified without identifying supporting evidence
   4. D.Present a proposed correction in place of the evidence for a finding

   Explanation: EPA audit guidance states: "Audit findings and the objective evidence for them are the subject of the closing meeting." A closing meeting communicates findings along with the evidence supporting them.

   Reference: EPA Guidance on Technical Audits and Related Assessments — 3.2.8 Closing Meeting, p. 46

9. 9How should a written nonconformity statement relate to its audit evidence?

   1. A.It should state the nonconformity without replacing the evidenceCorrect answer: A
   2. B.It should replace the need to document audit evidence
   3. C.It should consist solely of the auditor's unsupported opinion
   4. D.It should be identical to the proposed corrective action

   Explanation: ISO guidance says a nonconformity statement should "not be a restatement of the audit evidence, or be used in lieu of audit evidence." The statement and evidence have distinct roles.

   Reference: ISO 9001 Auditing Practices Group: Documenting Nonconformities — Documenting nonconformities, p. 2

10. 10According to EPI, what is the planned surveillance timing during a three-year TIA-942 Site/Facilities Certification cycle?

    1. A.By the end of years one and twoCorrect answer: A
    2. B.By the end of years two and three
    3. C.By the end of year one alone
    4. D.By the end of year two alone

    Explanation: EPI states: "By the end of year-1 and year-2, the data center should undergo a surveillance audit." Surveillance is addressed in the first two years of the certification period.
