質問 # 29
Which statement describes maintenance in a data center context?
正解：A
質問 # 30
Which two features does a one-line diagram show?
正解：C、D
解説：
An electrical one-line diagram , also called a single-line diagram, represents the major components and connectivity of an electrical distribution system using standardized simplified symbols. It allows technicians to understand how power moves from sources through transformers, switchgear, UPS systems, distribution equipment, and ultimately electrical loads.
Consequently, UPS and generator connections supporting backup distribution loads (A) and utility sources feeding the main electrical distribution equipment and loads (D) are appropriate information for a one-line diagram. Oracle's current data-center design requirements explicitly identify electrical one-line diagrams as part of the electrical design package and associate them with load calculations, breaker coordination, failure matrices, PDU information, panel information, and rack-to-breaker mapping. Oracle also specifies separate power paths backed by independent UPS systems and emergency generation for critical loads.
Option B describes dynamic operational response or switching alignment associated with alarms rather than the fundamental topology represented by the drawing. Option C concerns maintenance scheduling, which belongs in operational planning, change records, or maintenance-management documentation. The Study Guide emphasis is therefore on interpreting one-line diagrams as technical representations of electrical sources, components, distribution paths, and loads .
質問 # 31
Which two practices support clear status reporting during shift handover?
正解：A、B
解説：
Effective shift handover depends on objective, unambiguous, reproducible information . Reporting observations and measured values when available provides the incoming operator with factual evidence instead of interpretation. Using consistent equipment and location identifiers ensures that everyone is discussing the same asset, panel, rack, room, cooling component, or alarm source. Therefore, A and D are the appropriate practices.
Oracle's data-center curriculum emphasizes procedures-based operations, monitoring and alarm response, technical documentation, and professional operational behavior. Its more advanced technician curriculum also emphasizes incident ownership and operating within a 24/7 environment using structured workflows. These principles require continuity between outgoing and incoming shifts.
Option B is weak because a "most likely" root cause based solely on experience introduces assumption and can anchor subsequent troubleshooting incorrectly. Option C contains current status, which is useful, but "best related time estimates" can introduce unsupported or speculative information. Reliable handover communication should clearly distinguish measured facts from hypotheses and estimates. The incoming shift must be able to determine exactly what was observed, where it occurred, what remains abnormal, and what actions are pending without having to reinterpret undocumented assumptions.
質問 # 32
Which statement describes maintenance in a data center context?
正解：A
解説：
Data-center maintenance encompasses planned preventive work and corrective work performed to preserve or restore safe, reliable equipment operation . This makes B the technically correct definition.
Planned maintenance addresses inspection, servicing, testing, adjustment, replacement, and other activities performed before failure. Corrective maintenance responds to identified degradation or failure and restores the affected system to an acceptable operating condition.
Oracle Data Center Operations Foundations emphasizes procedures-based critical-facilities operation, including mechanical and electrical fundamentals, response procedures, standard operating procedures, technical documentation, and safe professional behavior. Those disciplines depend on maintaining critical infrastructure in a controlled condition rather than treating maintenance as ordinary shift monitoring or emergency response.
Option A describes routine operational monitoring and shift turnover rather than maintenance itself. Option C represents emergency operations following an abnormal event such as utility failure; emergency response can involve equipment manipulation but is not the definition of maintenance. Option D describes a narrow controls-engineering activity and therefore cannot represent maintenance broadly. In reliability-centered data- center operations, the purpose of maintenance is to preserve equipment availability, safety, predictable performance, and infrastructure resilience.
質問 # 33
Which three sensor readings can support environmental monitoring in a data center?
正解：A、C、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 .
