質問 # 22
What function does Computer Room Air Conditioner (CRAC) perform in a data center?
正解：A
質問 # 23
Which redundancy benefit supports uptime during component failures?
正解：B
解説：
The principal availability benefit of redundancy is that a component can fail without immediately interrupting the supported service , making D correct. When sufficient redundant capacity remains online, the affected system continues carrying its required load while operators diagnose the condition, escalate the incident, replace equipment, or execute an approved recovery procedure.
Oracle's N+1 power documentation illustrates this directly: the additional power supply assumes the required load after another supply fails so that system uptime can be maintained. Oracle's current Dedicated Region facility requirements similarly state that electrical infrastructure should avoid single points of failure and remain tolerant during failure conditions.
A concerns incident management rather than redundancy. Incident ownership is important operationally, but redundancy itself does not assign personnel. B is incorrect because redundant systems normally add equipment and therefore do not inherently reduce maintenance requirements. C describes monitoring visibility; redundant components may produce additional telemetry, but monitoring accuracy is not the primary availability benefit.
Redundancy therefore creates an operational buffer . It turns some component failures from immediate service outages into controlled abnormal conditions, providing technicians valuable time to respond while critical loads continue operating.
質問 # 24
When communicating during an incident, which detail should be included to support fact-based escalation?
正解：C
解説：
C is correct because effective incident escalation should communicate verified observations rather than speculation . Reporting what changed, where the change occurred, and what the monitoring system currently shows gives the receiving operator or lead three critical pieces of information: the observed condition, its location, and objective supporting evidence.
Oracle's Data Center Operations Foundations curriculum explicitly includes monitoring, alarms, response procedures, technical documentation, and professional operating behavior. Oracle Enterprise Manager's incident framework similarly tracks concrete incident attributes including severity, status, priority, ownership, escalation level, and administrator comments used to communicate analysis and actions.
A is flawed because maintenance activity should not be reported as the presumed explanation before confirming the affected equipment and current condition. B introduces prediction rather than current fact. D is especially weak because it reports a possible cause before evidence has been reviewed, potentially anchoring subsequent responders on an incorrect diagnosis.
Reliable incident communication follows a simple discipline: observe, verify, identify, communicate, and then investigate causation . The escalation should clearly distinguish what is known from what remains a hypothesis. This reduces confusion and enables faster, safer operational decision-making.
質問 # 25
Which statement describes maintenance in a data center context?
正解：C
質問 # 26
Which two conditions are mechanical hazards?
正解：B、C
解説：
C and D are mechanical hazards because both involve physical energy capable of causing injury through movement, impact, entanglement, or an uncontrolled mechanical release. Rotating shafts, fan blades, couplings, belts, and similar machinery can catch clothing, strike personnel, or create pinch and entanglement hazards. Oracle hardware safety documentation explicitly warns that moving fan blades constitute hazardous moving parts and instructs personnel to remain clear of them.
Pressurized mechanical systems-including chilled-water, condenser-water, refrigerant, pneumatic, or hydraulic systems-can retain energy even when associated equipment appears stationary. An uncontrolled release can propel fluid, fittings, or components and therefore must be treated as a stored-energy hazard.
Options A and B are serious hazards, but both are primarily electrical rather than mechanical. Damaged insulation can expose energized conductors, while water near energized equipment can increase electric-shock and fault risk.
Oracle Data Center Operations Foundations explicitly places safety-first behavior alongside electrical and mechanical fundamentals as core entry-level competencies. Correct hazard classification matters because the applicable controls-PPE, isolation, lockout/tagout, restricted access, or escalation-depend on understanding the energy source involved.
