問題 #32
The data center is conducting a needs analysis.
Which of the below is an activity of the needs analysis?
答案:B
解題說明:
Needs Analysis determineswhat the customer or business requiresfrom a service.
This includes:
* Required service hours / operating hours
* Availability expectations
* Business functional requirements
* Legal and compliance requirements
* Physical infrastructure needs (power, cooling, space)
* Performance and capacity needs
Identifying operating hoursis a core part of defining service requirements.
Why other options are incorrect:
* B: Current resource usage is part of infrastructure assessment, not needs analysis.
* C: Staffing is part of capability assessment.
* D: Monitoring requirements come after service definition and design.
Thus,Ais correct.
EPI DCFOM-Aligned Reference Concepts (Paraphrased)
* Needs analysis determines service operation hours, business needs, and requirements.
* It precedes capability assessment and service design.
問題 #33
What is defined by the Recovery Time Objective (RTO)?
答案:D
解題說明:
In organizational resilience and business continuity planning, theRecovery Time Objective (RTO)is a core metric used to determine the acceptable downtime for each business function.
EPI defines RTO as the:
"Targeted duration within which disrupted services or processes must be restored to a minimum acceptable operational level after a disaster." Key points:
* Timeframe for RecoveryThe RTO identifieshow quicklya facility, system, or service must be restored before the outage causes unacceptable consequences.
* Minimum Service CapacityThe RTO refers to restoring operationsat a minimum acceptable level, not full normal operations.
* Business Impact Analysis (BIA) OutputRTO is derived during BIA where criticality and dependencies of business processes are assessed and prioritized.
* Prioritization of ResourcesRTO informs disaster recovery planning, resource allocation, and restoration sequencing.
Therefore, the correct definition matches:
D - "The prioritized timeframes for resuming disrupted activities at a specified minimum acceptable capacity." Why the other options are incorrect:
* Adescribes the MTPD (Maximum Tolerable Period of Disruption).
* Bdescribes elements of the Minimum Business Continuity Objective (MBCO).
* Cdescribes the Recovery Point Objective (RPO).
EPI DCFOM-Aligned Reference Concepts
* RTO defines the permitted downtime for a service.
* RTO is linked to minimum acceptable capability after recovery.
* RTO is determined through BIA.
問題 #34
According to the World Economic Forum, which of the below is the largest global risk of the next decade?
答案:D
解題說明:
While not strictly internal to EPI's core domain (which deals with data centre operations), this question refers to the external risk landscape, as identified by the World Economic Forum (WEF). The WEF'sGlobal Risks Report 2025shows thatenvironmental risks dominate the 10-year horizon, with extreme weather, ecosystem collapse, and climate-related disruption ranking highest.
Specifically,global climate change(or extreme weather/climate-related events) is rated as the most severe risk over the next decade. While water scarcity and air quality are significant, the WEF ranks climate change / extreme weather as the top long-term threat. Therefore, optionAis the most correct.
EPI DCFOM-Aligned Reference Concepts (Paraphrased)
* Environmental sustainability forms a major component of data centre operations risk and resilience planning.
* External macro-risks such as climate change must be integrated into facility resilience, power planning, cooling design, and business continuity strategies.
問題 #35
Welding works need to be conducted.
Is a Permit to Work (PTW) required and if so, what type of PTW?
答案:D
解題說明:
EPI's Permit to Work (PTW) system categorizes work activities based on risk levels to ensure safe execution and hazard control within the data center.
Welding operations involveopen flame, sparks, high heat, molten metal, and ignition sources, making them a high-risk activity.
In EPI safety doctrine,welding is explicitly classified under "Hot Work." Hot Work includes activities such as:
* Welding
* Cutting
* Grinding
* Brazing
* Soldering
* Flame use or spark-producing tools
Because of the fire ignition potential, aHot Work Permitis mandatory before welding can begin.
The Hot Work PTW ensures:
* Fire watch personnel are assigned
* Fire suppression systems are prepared or temporarily disabled with compensating controls
* Surrounding area is inspected for combustible material
* Correct PPE is used
* Hot-work zoning, barriers, and extinguishers are in place
* Post-work monitoring is performed
Therefore,Option D (A PTW is required for hot work)is the correct and EPI-aligned answer.
EPI DCFOM-Aligned Reference Concepts (Paraphrased, Not Verbatim)
* The PTW system ensures hazardous activities are controlled.
* Welding is classified as Hot Work.
* Hot Work requires a dedicated PTW with fire-risk mitigation and supervisory approval.
問題 #36
What is the formula to calculate the PUE of a Data Center?
答案:C
解題說明:
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.
