In EPI’s organizational framework, ajob descriptionis a core document used to clearly define:

Responsibilities

Tasks

Required skills

Reporting relationships

Expected deliverables

Operational boundaries

The primary purpose is to ensureclarity of job scope, which enables:

Alignment of responsibilities

Prevention of role ambiguity

Proper expectation setting

Performance evaluation transparency

Workforce planning

While job descriptions may indirectly influence salary, promotions, or career paths, these arenottheir primary purpose.

Thus, the correct answer isB.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

Job descriptions define job scope, tasks, and responsibilities.

They support clarity and alignment within the organizational structure.

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’s safety and statutory requirements training emphasizes thatsafety is a shared responsibilityacross the entire data center organization. While roles such as the safety manager and facilities manager provide leadership, guidance, oversight, audits, and enforcement of safety procedures, they alone cannot ensure a safe workplace. Every individual working in or around the data center—whether employees, contractors, vendors, or visitors—has the responsibility to follow safety procedures, report hazards, use required protective equipment, and stop unsafe activities.

This collective responsibility approach ensures that risks are recognized early, unsafe conditions are not ignored, and safety culture is embedded throughout daily operations. The safety manager establishes policies, training, audits, and compliance frameworks; the facilities manager ensures operational processes support safety; the managing director endorses governance and resources. However,frontline workers are the most exposed to hazards, making their behavior critical.

Option C is correct because EPI emphasizes that safety cannot be delegated solely to one role; it must be embraced byall staff, ensuring a consistent, safe working environment. Data centers operate high-voltage systems, heavy equipment, and complex mechanical infrastructure, making shared vigilance essential for preventing incidents and ensuring regulatory compliance.

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 a co-location environment, the data center operator manages the facility infrastructure—power, cooling, space, security—but does not directly control how customers operate their IT equipment. However, sustainability programs aim to reduce total energy consumption, which includes IT loads. Since the operator cannot mandate hardware usage or impose arbitrary power reductions, the appropriate method ispromoting awareness and issuing recommendationsthat help customers optimize their systems.

These recommendations may include best practices such as consolidating workloads, improving server utilization, removing unused equipment (“zombie servers”), adopting more efficient storage architectures, using virtualization, and refreshing legacy hardware. This aligns with EPI’s sustainability principles, where collaboration and customer education play a key role in reducing energy consumption in shared environments.

Option A is incorrect because, although customers control IT loads, the operatorcaninfluence them through guidance and programs. Option B is unsafe and violates contractual power allocations. Option D imposes limitations not covered by typical co-location contracts and could disrupt customer operations.

Thus,providing optimization recommendationsis the best and most realistic approach.

EPI defines several facility options for Business Continuity:

Company-owned facility→ highest cost

Co-location→ moderate to high cost

Government-owned facility→ typically not a commercially viable or general-purpose BC option

Disaster Recovery (DR) provider→lowest-costsolution for BC

ADR provideroffers:

Shared or subscription-based DR facilities

Lower capital investment

Pay-as-you-use or retainer-based access

Rapid availability without owning infrastructure

Minimal financial burden for standby capacity

This aligns with management’s goal:cheapest possible alternative facility.

Thus,D – DR provideris correct.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

DR provider facilities are the most economical BC facility option.

They provide shared resources and reduce capital expenditure.

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.

Equipment Life Cycle Management (ELCM) in the EPI framework refers toa structured process ensuring that all physical infrastructure and supporting equipment remain continuously fit for their intended operational purposethroughout their lifespan.

This involves:

Planning

Commissioning

Operation

Maintenance

Upgrades / Refurbishment

Replacement

Decommissioning

The objective iscontinuous serviceability, not simply determining life expectancy or cost.

Why the other options are incorrect:

A: Technical lifetime assessment ispart oflife cycle management, not the entire scope.

B: Budgeting is only one output of ELCM, not its purpose.

C: Economic lifetime is anothercomponent, but not the definition of full life cycle management.

Thus, the only correct comprehensive definition isD.

EPI DCFOM-Aligned Reference Concepts (Paraphrased)

Equipment life cycle management ensures ongoing fitness-for-purpose of all facility systems.

Covers concept-to-retirement management of assets.
