Question 1

The following inlet temperature range is advised by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE):

Accepted Answer

68° to 77°

Answer

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) provides industry standards for data center environments. Their recommended inlet temperature range for IT equipment is 68° to 77°F (20° to 25°C). This range ensures optimal equipment performance and reliability while allowing for energy efficiency in cooling.

Question 2

Which percentage of a big (25,000–50,000 sq ft data center) accounts for the majority of its annual running costs, according to a recent study by The Ponemon Institute?

Accepted Answer

41%

Answer

According to studies by The Ponemon Institute, power and cooling expenses constitute the largest portion of a data center's operational budget. For large data centers, these energy-related costs can account for approximately 41% of the total annual running costs, making energy efficiency a critical focus.

Question 3

For every 1°F rise in server inlet temperature, how much may energy expenses be reduced in data centers, according to Energy Star?

Accepted Answer

Up to 4%

Answer

Energy Star, a program by the U.S. Environmental Protection Agency, highlights energy-saving opportunities in data centers. They indicate that for every 1°F increase in server inlet temperature, within the recommended operating range, data centers can reduce energy expenses by up to 4% due to decreased cooling demands.

Question 4

What component of the following DOES NOT belong in a data center?

Accepted Answer

None of the above

Answer

A data center is fundamentally built to house and operate IT infrastructure. Networking components are essential for communication, memory is crucial for processing, and storage systems are vital for data retention. Therefore, all listed options are integral and necessary components within a data center environment.

Question 5

Which of the following businesses rent or lease their data center capabilities to other businesses?

Accepted Answer

Both a and b

Answer

Companies like Dell and IBM are prominent technology providers that offer extensive data center services.
