EPI Data Centre CDFOM Dumps PDF

Power Usage Effectiveness (PUE) is the most widely recognized efficiency metric in the data center industry and is strongly emphasized within EPI's environmental sustainability and energy management teachings. PUE is designed to show how efficiently a data center uses energy, focusing specifically on how much of the total facility energy actually reaches the IT equipment. The correct formula is:

PUE = Total Facility Power ÷ Total IT Equipment Power

“Total Facility Power” includes all supporting infrastructure: cooling systems, UPS losses, power distribution losses, lighting, security, fire systems, and all auxiliary loads required to operate the data center. “Total IT Equipment Power” refers only to the active IT load such as servers, storage, and network devices.

A PUE value close to1.0indicates optimum energy efficiency, meaning nearly all facility energy is being consumed directly by IT operations. Higher PUE values indicate less efficient facilities where substantial energy is being consumed by overhead systems. This metric is essential for sustainability strategies, capacity planning, and continuous improvement. It allows benchmarking across facilities and helps operators set improvement targets by analyzing where energy losses occur. Because of its simplicity and clarity, PUE remains an industry-standard metric recognized globally.

Training must be aligned with actual operational needs and competency gaps.

Theskills matrixis the tool that provides:

Current skill levels of staff

Required skill levels per role

Identified gaps

Training needs based on operational requirements

Therefore, the first step is toreview the skills matrixto determine what training is actually needed.

Why other options are incorrect:

A: Service catalog inventory is part of SLM, not training selection.

B: Contacting vendors is premature without knowing training needs.

D: Price comparison should occur later, after training needs are defined.

Thus,Cis correct.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

Skills matrix is the foundation for determining training needs.

Training selection must be based on capability gaps, not brochures or pricing.

Among maintenance contract models, theLowest-Riskoption is the:

Comprehensive Contract

A comprehensive maintenance contract includes:

Preventive maintenance

Corrective maintenance

Replacement parts

Labor costs

Priority response times

Faster repair and recovery

Predictable costs

Strong service guarantees

Higher reliability and lower operational risk

Why other options are incorrect:

A – Basic: Limited coverage; higher risk of delays.

B – Time & Material: Highest financial and operational risk.

D – Exclusive: Typically an enhanced premium model but not the primary “lowest risk” category in EPI’s standard contract structure.

Thus,Cis correct.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

A comprehensive contract provides the lowest operational risk for critical infrastructure.

Offers full-service coverage and fastest response times.

Operational Expenditure (OPEX) includes all ongoing costs required to operate and maintain the data center on a day-to-day basis. These costs are recurring and necessary to keep the facility functioning effectively. Examples of OPEX include staffing costs, service contracts, maintenance materials, consumables, utilities, and recurring software licensing fees. Within EPI’s Facilities Management guidance, maintenance activities—such as replacing fans, belts, filters, and other wear-and-tear components—are classic OPEX items because they occur during normal operational cycles, contribute to sustaining facility uptime, and repeat regularly over the equipment lifetime.

However,acquisition of real estateis a capital-intensive investment made once during facility development and falls underCapital Expenditure (CAPEX), not OPEX. CAPEX involves large, long-term investments such as land purchase, building construction, major equipment procurement, or infrastructure upgrades. These expenditures are depreciated over years and do not represent operational overhead.

Therefore, the only option not belonging to OPEX isC – Acquisition of real estate. Staffing, maintenance material replacement, and annual software licenses are standard OPEX items essential for continuous operation, service delivery, and compliance with operational practices.
