質問 # 16
Which two statements describe N+1 redundancy?
正解：A、C
解説：
N+1 redundancy means that the infrastructure contains the number of components required to support the design load- N -plus one additional component capable of maintaining required capacity when one necessary component becomes unavailable. Consequently, A and B are correct.
Oracle documentation provides a direct example for power supplies: N represents the number of supplies required to power the fully configured system, while the additional "1" handles the load if one supply fails.
This allows the system to continue operating after a single component failure. Oracle's current data-center facility guidance likewise expects resilient electrical architectures such as N+1 or 2N where appropriate.
C describes an N configuration , because only the capacity necessary for normal operation is present. Such a configuration has no spare unit to absorb a component failure.
D instead describes architecture closer to 2N , where two independent capacity sets can each support the complete required load. That provides a different and generally stronger level of redundancy.
The examination distinction is therefore: N = required capacity only; N+1 = required capacity plus one redundant unit; 2N = two independent full-capacity systems .
質問 # 17
Which measurement does a multimeter check?
正解：B
解説：
A multimeter is an electrical test instrument capable of measuring quantities such as voltage, resistance, and-depending on configuration-current and continuity . In this question, B is therefore correct:
voltage measurement confirms electrical potential or potential difference at the selected test points.
Oracle documentation provides a direct example of configuring a multimeter to read DC voltage , connecting its test leads between a GPIO output and ground, and observing voltage changes between approximately 0 V and 3.3 V. This illustrates the fundamental use represented by the answer.
Humidity requires an environmental humidity sensor or hygrometer. Airflow is measured using instruments such as an anemometer or airflow meter. Differential pressure requires an appropriate pressure-measurement instrument or sensor, not an ordinary electrical multimeter by itself.
Oracle Data Center Operations Foundations requires learners to understand key electrical concepts and to use technical documentation and basic tools appropriately. Tool literacy also includes understanding limitations: selecting the correct meter function, range, rated leads, test category, and approved procedure is essential around energized systems.
For the examination, associate the multimeter with fundamental electrical measurements-particularly voltage, resistance, continuity, and current where appropriately configured .
質問 # 18
Which three sensor readings can support environmental monitoring in a data center?
正解：A、D、F
解説：
The question specifically asks for sensor readings relevant to environmental monitoring. Differential pressure (B) is a measured physical parameter used to evaluate pressure relationships and airflow behavior across rooms, aisles, or containment boundaries. Rack inlet temperature (C) directly measures the thermal environment presented to IT equipment and can reveal localized cooling deterioration. Chilled-water flow (D) is another measured physical value that helps operators determine whether cooling coils are receiving adequate water flow.
Oracle's environmental guidance emphasizes controlled temperature, adequate airflow, and monitoring at multiple points because environmental conditions are not uniform throughout a computer room. Oracle also requires hot-aisle/cold-aisle containment and appropriate pressure relationships in its modern data-hall facility requirements.
Access-control logs in A are security records rather than environmental sensor measurements. Work-order status in E is maintenance documentation, and the calendar in F is a planning record. Although all may contribute to operating a facility, none of those three represents an environmental process measurement.
Consequently, the three applicable physical sensor readings are B, C, and D .
質問 # 19
Which statement correctly defines resistance?
正解：A
解説：
Electrical resistance is the opposition that a material or circuit presents to the flow of electrical current.
Therefore, D is correct. Resistance is measured in ohms (#) and is one of the fundamental variables expressed by Ohm's law: . For a given applied voltage, increasing resistance reduces current; reducing resistance allows more current to flow.
The other options describe different electrical quantities. A defines current , which is the rate of flow of electric charge and is measured in amperes. C defines voltage , or electrical potential difference, measured in volts. B does not correctly define a standard electrical quantity; the rate at which electrical energy is transferred or converted is power , normally measured in watts.
Oracle's Data Center Operations Foundations curriculum explicitly identifies understanding key electrical concepts as an expected foundational competency for critical-facilities personnel. Oracle's data-center electrical documentation also emphasizes distribution design, circuit protection, grounding, impedance, load planning, and stable power as fundamental facility considerations.
For exam purposes: voltage drives current, current is charge flow, resistance opposes current, and power represents the rate of energy transfer .
質問 # 20
What function does a transformer perform in electrical distribution?
正解：C
解説：
A transformer transfers electrical energy between circuits by electromagnetic induction and is principally used in power-distribution systems to change AC voltage levels . Therefore, C is correct. In a data center, transformers commonly step facility distribution voltage up or down to a level appropriate for downstream switchgear, distribution panels, PDUs, or IT-supporting infrastructure.
Oracle's Data Center Operations Foundations curriculum includes key electrical concepts as a core competency for entry-level critical-facilities personnel. Oracle's facility power documentation similarly requires operators and planners to understand supplied voltage, equipment operating voltage, branch circuits, distribution systems, grounding, PDUs, and appropriate circuit protection.
Option A more closely describes the arrangement and control functions associated with switchgear or distribution assemblies. Option B confuses a transformer with bonding and grounding , whose purpose is to establish safe conductive paths and electrical potential relationships. Option D describes overcurrent protection performed by devices such as circuit breakers or protective relays acting with breakers.
For certification purposes, associate the major electrical functions distinctly: transformer = voltage transformation; breaker = overcurrent interruption/protection; switchgear = switching, protection, control, and isolation; UPS = short-duration uninterrupted conditioned power .
