Question 1

What are the two main applications for ac (alternate current)?



Answer : C

The two main applications for AC (alternate current) are power and information. AC is used to generate and transfer power to electrical devices, and is also used to carry information signals in telecommunications.


Question 2

___________ protects electrical equipment from damage caused by overload or short circuit.



Answer : A

A circuit breaker is a device that protects electrical equipment from damage caused by overload or short circuit. It does this by automatically disconnecting the power supply when it detects a surge or drop in voltage, preventing the equipment from being damaged.


Question 3

Which mounted system is used to cool small IT environments?



Answer : A

An air mounted system is often used to cool small IT environments. This type of cooling system is typically mounted on the wall or ceiling and works by blowing cool air into the room to lower the temperature. Air mounted systems are compact, easy to install and maintain, and can be a cost-effective solution for small spaces.


Question 4

Which type of power can be a source available to the data center that takes over the function of supplying when utility power is unavailable?



Answer : A

Standby power, also known as backup power, is a type of power that can be a source available to the data center that takes over the function of supplying when utility power is unavailable. Standby power systems are designed to provide power to critical loads in the event of a power outage, and can include generators, uninterruptible power supplies (UPS), and batteries. Standby power systems can be used to provide power to the data center for a short period of time, such as a few hours or days, until utility power is restored.

Passive, Active and Alternate are not specific type of power sources used in data center. They are terms used in different context and have different meaning.


Question 5

A __________ generator system is a combination of an electrical generator and a mechanical engine mounted together to form a single piece of equipment.



Answer : B

A Standby Generator System is a combination of an electrical generator and a mechanical engine mounted together to form a single piece of equipment. The generator provides power to essential appliances and equipment in the event of a power outage. Standby Generator Systems are usually powered by gasoline, diesel, natural gas, or propane, and they are designed to be able to be activated quickly in the event of an emergency.


Question 6

If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?



Answer : A

Frequency is the inverse of period, so to calculate the frequency of a signal with a period of 10 microseconds, you would divide 1 by the period, which is equal to 100 kHz.


Question 7

Data Center Precision Cooling Systems maintain temperature within _____________ degree(s) of their design set point.



Answer : A
