質問 # 18
Which arrangement describes a colocation data center?
正解：D
解説：
A colocation data center is a facility operated by a third-party provider in which multiple customers can place their own IT and networking equipment while using shared physical infrastructure such as floor space, power, cooling, security, and connectivity. Therefore, D correctly describes the model.
Oracle's OCI networking documentation explicitly discusses customers that have purchased colocation space from a data center provider and then connect network equipment located in that colocation facility to OCI through FastConnect. This directly reflects the defining characteristic of colocation: the customer maintains equipment presence inside infrastructure operated by another facility provider.
A describes an enterprise/private data center , where an organization operates infrastructure primarily for its own workloads. B describes a hybrid architectural arrangement rather than a data-center facility type. C is closer to a cloud or hyperscale provider operating its own infrastructure.
Oracle Data Center Operations Foundations requires understanding fundamental data-center concepts and critical-facility roles. For certification purposes, the critical distinction is ownership and tenancy : enterprise facilities support one organization's internal environment, while colocation facilities provide shared physical infrastructure in which independent customers deploy their own equipment.
質問 # 19
Which three actions align with following a procedure as written?
正解：A、D、F
解説：
Following a procedure as written means executing required controls without independently modifying, reordering, or omitting procedural steps. Therefore, B, D, and E are correct.
If the procedure requires a peer check, that verification must occur before proceeding. Required steps must be completed in the specified sequence because procedure order can be essential to equipment state, personnel safety, redundancy, and reliability. Actions and observations should also be documented so there is an accurate operating record and sufficient information for subsequent verification, handover, troubleshooting, or incident review.
Oracle explicitly characterizes Data Center Operations Foundations as a safety-first, procedures-based learning environment and requires learners to follow standard operating and emergency procedures. Oracle's production change-management practices similarly emphasize controlled implementation, validation, approval, and the ability to recover safely from operational problems.
A, C, and F all introduce unauthorized procedural deviation. Even an experienced operator should not improvise by reordering steps, inserting an alternate method, or eliminating required verification simply because conditions appear normal. If the approved procedure no longer matches actual conditions, the correct reliability behavior is to stop, escalate, and obtain appropriate direction or an approved procedural change , rather than modifying the procedure during execution.
質問 # 20
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 # 21
If a new alarm appears after earlier service work, what should be reviewed first to reduce guesswork during escalation?
正解：A
解説：
The most useful first review is the work-order history and maintenance log for the affected equipment , making D correct. If an alarm occurs after prior service activity, the technician needs to determine exactly what work was performed, when it occurred, what components were affected, what status changes were recorded, and whether any relevant observations or follow-up items were documented.
Oracle Maintenance provides chronological maintenance-transaction history associated with assets and work orders, enabling users to review recent activity and verify maintenance actions. Oracle's technician-oriented maintenance interface also allows technicians to review service history for the asset , research prior information, and create handover notes during execution.
A creates new documentation before first understanding the existing history. B contains useful information, but an equipment list is less diagnostically relevant than the specific work-order and maintenance record for the affected asset. C may help when the alarm is thermal, but room-average temperature is too narrow and may not be related to the event.
Reviewing the specific equipment's documented maintenance history reduces speculation and allows escalation to include verified recent interventions and observed outcomes , rather than assumptions about whether earlier work contributed to the new alarm.
質問 # 22
Before beginning a maintenance task, how should PPE be selected?
正解：D
解説：
PPE must be selected after assessing the hazards associated with the specific task and determining which parts of the body may be exposed , making B correct. PPE is a hazard-control measure, so its selection must correspond to the actual energy sources and exposures present-such as electrical, mechanical, chemical, thermal, impact, or other physical hazards.
Oracle Data Center Operations Foundations explicitly places safety-first and professional behavior at the center of critical-facilities preparation. Oracle's Workforce Health and Safety documentation also distinguishes unsafe conditions by hazard category and identifies both incorrect use of PPE and failure to follow Job Safety Analysis as unsafe acts. This reinforces the required sequence: identify the hazard, determine exposure, and then apply the prescribed protection.
A is unsafe because previous similar work does not prove that present conditions or hazards are identical, and availability does not determine suitability. C delays PPE selection until exposure has already begun. D substitutes preference for hazard-based requirements.
For examination purposes, PPE selection should be viewed as part of pre-job hazard assessment , not as an optional personal choice or reactive measure after work has started.
