EXIN EPI Certified Data Centre Specialist 認定 CDCS 試験問題 (Q11-Q16):質問 # 11
What is the effect of having a damper (in open position) construction in a raised-floor tile?
  • A. Dampers reduce the air volume by approximately 10%
  • B. Dampers allow for a higher supply air temperature
  • C. Dampers can be used when there is a high rate of temperature change in the computer room
  • D. Dampers increase the air volume by approximately 10%
正解：A
解説：
Perforated tiles with integrated dampers are common in raised-floor data centers because they allow airflow regulation at the rack level. However, even when the damper is fully open, the mechanism inside the tile restricts airflow. This typically reduces the delivered airflow by around 10% compared to a non-dampered tile of the same type.
* Option A is incorrect because dampers do not affect supply temperature; they only throttle volume.
* Option B is wrong since dampers cannot increase volume-they only add resistance.
* Option D is partially true that dampers help with temperature balancing, but the main effect (in open position) is volume reduction.
Thus, the technical impact of dampers in open position is a slight airflow reduction, usually quantified as
~10%.

質問 # 12
The UPS of a data center, with an ANSI/TIA-942 Rating-4, is installed with the rectifier connected to power feed A and the bypass/reserve line input connected to power feed B.
To which feed will the output of the UPS be synchronized?
  • A. Feed A
  • B. The UPS will not synchronize to any of the feeds but use an internal clock to set the output voltage and frequency
  • C. Depends on the setting of the UPS, as the UPS can normally be set to either feed
  • D. Feed B
正解：C
解説：
For a UPS system in a Rating-4 data center, the synchronization of output can indeed depend on the specific settings of the UPS. Generally, such systems allow for flexible configuration where the output can be synchronized to either power feed A or B, depending on which feed is preferred for stability or redundancy purposes.
Detailed Explanation:
In dual-feed setups, such as those in high-redundancy data centers, the UPS can be set to synchronize with either feed. This ensures that the UPS maintains continuity in case one feed becomes unstable or fails. The flexibility to choose synchronization to either feed enhances the resiliency and reliability of power supply, which is critical in Tier IV (Rating-4) facilities where uptime is paramount.
EPI Data Center Specialist References:
The EPI Data Center Specialist course underscores the importance of configurable UPS systems in Rating-4 data centers, where redundancy and continuous power are critical. By allowing synchronization to either feed, the UPS can maintain the highest level of reliability, which aligns with the rigorous standards expected in such environments.

質問 # 13
What is the minimum requirement for power feeds to a Rated-4 data center (ANSI/TIA-942)?
  • A. Two feeds from one substation
  • B. Two feeds from two different substations, one power company acceptable
  • C. One feed split into two distribution boards
  • D. Two feeds from two different substations, one power company not acceptable
正解：B
解説：
A Rated-4 facility requires dual active utility feeds, each from an independent substation, but they may come from the same utility provider if substations are geographically separate and independent.
* Option A is too strict; ANSI/TIA-942 does not mandate two different companies.
* Options C and D do not provide true independence and would fail Rated-4 requirements.
Thus, the minimum is two substations, possibly same provider.
References: ANSI/TIA-942-B §6.2 (Utility Service Requirements).

質問 # 14
When shielding material reaches its saturation point, what will be the impact?
  • A. The shielding material will reach its optimal shielding performance state.
  • B. The shielding material will reach its maximum electrically charged state.
  • C. The shielding material will no longer be able to attenuate (reduce) additional EMF.
  • D. The shielding material will increase its permeability factor.
正解：C
解説：
When shielding material reaches its saturation point, it can no longer effectively attenuate additional EMF. At saturation, the material's ability to absorb or redirect magnetic fields is exhausted, meaning it cannot provide further shielding beyond this point. Additional EMF exposure would pass through the material without significant reduction.
Detailed Explanation:
Saturation occurs when the material's magnetic domains are fully aligned with the magnetic field, leaving no capacity to absorb or deflect further EMF. This can happen with high EMF levels, beyond the material's design limits, resulting in a breakdown of shielding effectiveness.
EPI Data Center Specialist References:
EPI guidelines on EMF management indicate that selecting appropriate shielding materials with sufficient capacity is essential to prevent saturation and ensure continuous protection. Saturation limits should be considered during design to avoid compromised shielding performance.

質問 # 15
What is the minimum requirement for the power feeds to the building for a Rated-3 data center based on the ANSI/TIA-942 standard?
  • A. Two feeds coming from two different substations, one power company is acceptable
  • B. Two feeds coming from two different substations, one power company is not acceptable
  • C. One feed from one substation split over two separated distribution boards in separate rooms
  • D. Two feeds entering the data center building from one substation
正解：A
解説：
The minimum requirement for power feeds to a Rated-3 data center according to ANSI/TIA-942 is to have two independent power feeds, which can come from two different substations provided by the same power company. This ensures redundancy and concurrent maintainability, as each feed can support the load independently during maintenance or failure of the other.
Detailed Explanation:
The separation by two substations ensures resilience in case of a localized outage or substation maintenance, aligning with Rated-3 requirements for uninterrupted operation. ANSI/TIA-942 permits these feeds from a single utility provider as long as they are supplied from distinct substations.
EPI Data Center Specialist References:
EPI underscores the importance of dual power feeds from separate substations for Rated-3 facilities, highlighting that the ability to draw from different substations aligns with redundancy requirements for high availability.
