CDFOM Exam Dumps - Exin EPI Data Centre Questions and Answers

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.

EPI describes threecommonly offered maintenance service levelsin the data center industry:

Time & Material (T&M)

Pay per visit, per hour, and per part

No guaranteed response time

Lowest cost, lowest priority

Basic Contract

Includes scheduled preventive maintenance

Limited support for corrective issues

Faster response than T&M but still limited

Comprehensive Contract

Includes preventive + corrective maintenance

Parts + labor included

Priority response times

Best uptime protection

These are the standard, industry-recognized tiers reflected in EPI’s training.

Why the other options are incorrect:

AandBare marketing labels used in some industries but not standard for data center facility maintenance.

Cis not an EPI-recognized offering.

Thus,Dis correct.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

Standard vendor offerings include T&M, Basic, and Comprehensive contracts.

Used widely for UPS, generators, cooling systems, and electrical infrastructure.

In the context of defining services (after needs analysis) in the EPI framework, a good service definition should beSMART— Specific, Measurable, Achievable, Relevant, Time-bound. This ensures that the service can be consistently delivered, measured, controlled, and improved.

Specific: clearly defined service features and scope

Measurable: metrics and KPIs are defined

Achievable: realistic given resources and capabilities

Relevant: aligns with business/customer needs

Time-bound: has defined timelines for delivery and review

While following PDCA (Plan-Do-Check-Act) (option A) is good practice for continuous improvement, it is not what characterises aservice definition. Meeting ROI (option C) is business-case oriented, not a service definition criterion. Having an underlying SLA (option D) is related but not the core characteristic of a well-defined service itself.

Thus, the correct answer isB.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

Service definitions should be clear, measurable, and aligned with business/customer needs.

A SMART definition supports service design, delivery, monitoring, and improvement.

Customer satisfaction surveys must be concise, relevant, and easy to complete. EPI’s service improvement guidance emphasizes that survey fatigue occurs when surveys are overly long or contain too many detailed questions, causing customers to abandon them. The most common reason for low participation isexcessive number of questions, making the survey time-consuming or overwhelming. In modern service environments, customers expect short, focused surveys that can be completed quickly. Surveys with more than a handful of core questions often have dramatically reduced response rates.

Option A (not enough questions) would not reduce participation; shorter surveys typically perform better. Option B (not sent by the data center manager) may influence perception but does not typically impact participation significantly. Option D (postal mail) is outdated but still not as strong a factor as excessive survey length—especially because the question does not indicate this method was used.

Therefore, the most likely root cause for poor participation is thatthe survey had too many questions.

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.

When operators receive excessivenon-alarm notifications, this indicates that:

Thresholds are not well-configured

Events are misclassified

Alarm definitions are incorrect

Monitoring profiles require tuning

EPI’s monitoring best practices state that the correct response is to:

Review alarm information and adjust definitions, thresholds, and filtering.

This ensures that:

Only relevant alarms reach operators

Noise is minimized

Operators maintain focus on true issues

SLA-related metrics are accurately monitored

Why other options are incorrect:

A: Training is secondary and will not fix incorrect alarm settings.

C: Ignoring notifications is dangerous and violates operational control.

D: Upgrading software may not resolve the underlying configuration problem.

Thus,Bis correct.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

Monitoring systems must generate actionable alarms, not noise.

Alarm thresholds and event filters must be reviewed and optimized regularly.

In EPI’s project management framework, responsibility and accountability are clearly defined. While theproject manageris responsible for planning, coordinating, executing, monitoring, and controlling the project,accountability for the outcome rests with the business—the entity that sponsors the project. The business initiates the project, approves its objectives, allocates resources, provides governance, and ultimately benefits from or is impacted by the results. Therefore, success or failure of the project ties directly back to the business rather than the project manager or any other stakeholder.

The project manager has operational responsibility, but the business owns the strategic outcomes, investment risks, and long-term impact. The user/customer contributes requirements and feedback but is not accountable for overall delivery. The supplier delivers contracted components or services but does not own the full project lifecycle or outcome.

EPI emphasizes that accountability must reside with the sponsoring business to avoid gaps in ownership, unclear decision-making, and governance failures. This structure ensures that the project aligns fully with organizational objectives and that decisions support long-term value.

Thus, the correct answer isC – The business.

Power Usage Effectiveness (PUE) is the most widely recognized and adopted energy efficiency indicator for data centers globally and is emphasized heavily within the EPI sustainability framework. PUE measures how effectively a data center uses power and is calculated by dividing theTotal Facility Powerby theIT Equipment Power. The purpose of this indicator is to show how much of the energy consumed by the facility actually reaches IT equipment (servers, storage, network gear) versus how much is consumed by support infrastructure such as cooling, UPS losses, lighting, and building systems.

A lower PUE indicates a more efficient data center, with values approaching 1.0 representing ideal efficiency—where nearly all consumed power is being used for IT load. PUE is essential for benchmarking, energy-saving initiatives, identifying efficiency improvement opportunities, and measuring the success of infrastructure optimization projects. The other options listed—nil, w; CPU; and uw—are irrelevant to facility energy efficiency metrics. CPU relates to computing processors, not facility efficiency; the others are incorrect units or meaningless terms in this context.

Thus,PUEis the correct and industry-standard power efficiency indicator.
