質問 # 17
Which documentation entry would make follow-up difficult for the next shift?
正解：C
解説：
C would make follow-up difficult because it is vague and lacks the specific information required for operational continuity. "All cooling equipment was checked during rounds" does not identify which equipment was inspected, when each check occurred, what readings or conditions were observed, whether abnormalities existed, or whether further action is required.
Oracle Data Center Operations Foundations identifies technical documentation and procedures-based operation as foundational competencies. Oracle Maintenance documentation further states that work-order and operation notes are valuable as general or turnover notes during planning and technician execution, and that repair-summary information can provide an overview of work history.
A identifies CRAH-4, the work performed, its restoration to service, and the observed post-maintenance trend.
B provides a specific equipment identifier, timestamp, and abnormal observation. D identifies UPS-2, provides a timestamp, describes the alarm action, and states the verified condition.
Effective handover records should therefore contain enough specificity for another technician to reconstruct the operational event: equipment identifier, time, observed condition, action performed, resulting state, and any remaining follow-up . Generic statements such as C provide insufficient traceability.
質問 # 18
What is the purpose of a baseline in monitoring?
正解：A
解説：
A monitoring baseline establishes what normal operation looks like so that meaningful deviations can be identified, making A correct. A baseline may characterize normal temperatures, pressures, electrical loads, utilization levels, equipment behavior, or other recurring operating measurements over an appropriate period.
Operators and monitoring platforms can then compare current conditions with that reference to recognize abnormal trends.
Oracle's high-availability monitoring guidance explicitly discusses evaluating metrics against an established baseline and explains that threshold selection should take normal operating values and normal variability into account. Oracle states that understanding system performance data during normal operations is essential before selecting warning and critical thresholds.
B describes a response or escalation procedure, not a baseline. C describes a current or most recently recorded measurement. D confuses a baseline with a threshold . A threshold is a defined value at which a warning, critical alert, or other action may occur; it can be derived partly from baseline behavior, but the two concepts are not interchangeable.
The distinction is important for the exam: baseline = reference pattern of normal behavior; threshold = boundary that triggers attention; trend = change over time; alarm = notification that a defined condition has been met .
質問 # 19
Which two statements describe N+1 redundancy?
正解：B、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 # 20
Which statement describes maintenance in a data center context?
正解：B
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 # 21
Which three conditions indicate a cooling failure?
正解：B、C、F
解説：
B, C, and D represent genuine failure or degradation conditions. A sensor fault can impair detection and control response even if the mechanical equipment itself remains available. A cooling unit that stops while supply temperature rises is a direct equipment/cooling-capacity failure. Poor airflow producing localized hot spots is also a cooling-system performance failure because cooling effectiveness depends not merely on operating equipment but on delivering conditioned air to the IT intake and preventing exhaust recirculation.
Oracle requires adequate front-to-back airflow and warns that gaps, obstructions, and inadequate cold airflow can adversely affect cooling. Oracle also states that environmental conditions are not uniform across a data room and recommends monitoring at multiple points. Excessive rack temperature can decrease hardware reliability and ultimately lead to partial or complete shutdown.
A, E, and F describe expected or stable operation: supply temperature is near setpoint, system status and temperature are stable, or airflow and rack inlet temperatures remain within range. The key operational concept is that cooling failure can arise from equipment loss, control/sensor degradation, or airflow- distribution failure , not only from complete chiller or cooling-unit shutdown.
