Question

For a rack in a data center, how many temperature sensors are recommended?

Options

AThree
BTwo
CFour
DOne

Explanation

It is recommended to have three temperature sensors for a rack in a data center (see ISC2 Study Guide, Chapter 4, Module 3). These sensors should be placed at the top, middle, and bottom of the rack to accurately monitor the temperature throughout the rack. This helps ensure that all equipment in the rack is operating within the recommended temperature range and can help identify potential problems before they lead to hardware failure. Having only one or two sensors would not provide a comprehensive view of the temperature throughout the rack. Having four sensors could provide additional data, but it is typically not necessary and could add unnecessary complexity and cost.
