EPI’s financial management guidance distinguishes between several internal cost transparency models.Chargebackoccurs when costs are formally billed to internal departments or customers. However, in this scenario, management wants visibility of cost distributionwithoutmaking business units financially responsible. This aligns directly with theShow Backmodel.

Show Back is a non-billing mechanism that reports how much each business unit would hypothetically be charged if costs were allocated proportionally. It improves cost awareness, encourages responsible consumption, and helps management understand operational cost drivers without generating friction associated with real billing. Show Back is commonly used in organizations where financial culture, policy constraints, or strategic choices prevent the use of formal chargeback.

Options A (Chargeback) does not meet the requirement because it transfers costs. Options C and D are not recognized cost transparency models within EPI or general IT financial management practices.

Therefore, the most suitable model for cost transparencywithout financial transferisB – Show Back.

Within EPI’s Environmental Sustainability framework, theRenewable Energy Factor (REF)is the recommended metric for determining and reporting how much of a data center’s consumed power originates from renewable energy sources. REF provides a standardized, transparent, and repeatable method for calculating the renewable component of the total energy supply. This is essential because power grids draw energy from mixed sources, and data centers must demonstrate sustainability performance accurately and consistently, especially when customers demand visibility into carbon-related metrics.

Implementing REF allows the data center to quantify renewable contributions from sources such as solar, wind, hydro, geothermal, or certified renewable energy certificates. It also enables customers to compare sustainability performance across providers, improving trust and supporting corporate environmental objectives. REF becomes part of the data center’s transparency strategy, demonstrating commitment to responsible energy usage and aligning with global sustainability expectations.

Options A and B are insufficient and unprofessional; energy providers may give general data, but these are not standardized for reporting purposes. Option C is inappropriate because sustainability transparency is increasingly demanded even if not in the SLA. Therefore, implementing REF is the correct and industry-aligned response.

EPI defines several maintenance contract models, each offering different levels of service and support. In the scenario described, long repair time caused unacceptable downtime. To reduce risk, the organization needs a contract that provides:

Faster response

Faster repair time

Better availability of spare parts

Preventive and corrective coverage

Minimum downtime guarantees

Acomprehensive maintenance contractprovides:

Full service coverage

Labor + parts

Priority response levels

Faster restoration times

Predictable maintenance costs

Better uptime assurance

Increased provider accountability

Why the other options are incorrect:

A (Time & Material): Slowest and most unpredictable; not suitable for critical cooling systems.

B (Basic contract): Limited coverage; still leaves long repair times.

D (Exclusive contract): Typically refers to dedicated on-site or embedded teams, but not the standard EPI contract step-up for improved uptime.

Thus,C – Comprehensive contractis the best option.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

Comprehensive contracts provide enhanced support, faster repairs, and full coverage.

Suitable for critical infrastructure like cooling systems.
