Huawei H12-461_V1.0-ENU 問題集 練習問題・模擬試験｜日本語版＆英語版対応

サンプル問題 1： Regarding the working logic of the low-voltage bus tie switch, which of the following descriptions is correct?

• A: When the two mains power inputs of the data center come from different substations, a bus tie switch cannot be installed at the low voltage level. A bus tie switch can only be installed at the low voltage level when the two mains power inputs of the data center come from the same substation.
• B: Assuming the data center has two mains power inputs, A and B, and a tie switch is installed at its low-voltage bus, then during normal operation, only any two of the following switches will be closed: the mains power input circuit breaker for line A, the mains power input circuit breaker for line B, and the bus tie switch.
• C: Assuming the data center has two mains power inputs, A and B, and a tie switch is installed at its low-voltage bus, then during normal operation, only one of the following switches will be closed: the mains power input circuit breaker for A, the mains power input circuit breaker for B, and the bus tie switch.
• D: Assuming the data center has two mains power inputs, A and B, and a tie switch is installed at its low-voltage bus, then during normal system operation, three switches can be closed: the mains power input circuit breaker for A, the mains power input circuit breaker for B, and the bus tie switch.

サンプル問題 2： A data center's power supply architecture is as follows: dual mains power input from the same substation, 2N transformer configuration, no generators, 2N UPS configuration, dual-circuit power supply to the load, and one primary and one backup power supply link. Which of the following descriptions of this data center's power supply scheme is correct?

• A: This power supply solution meets the requirements of Uptime Tier II data centers.
• B: This power supply solution meets the requirements of Uptime Tier I data centers.
• C: This power supply solution meets the requirements of Uptime Tier III data centers.
• D: According to Uptime requirements, this computer room has no classification.
