Which of the following types of environmental equipment will MOST likely be deployed below the...

Water sensors are devices that can detect the presence of water or moisture in a given area. They are often deployed below the floor tiles of a data center to monitor for any water leaks that may damage the equipment or cause electrical hazards. Water sensors can alert the data center staff or trigger an automatic response to prevent or mitigate the water leakage.

The other options are not likely to be deployed below the floor tiles of a data center. Temperature sensors and humidity sensors are usually deployed above the floor tiles to measure the ambient conditions of the data center and ensure optimal cooling and ventilation. Air pressure sensors are typically deployed at the air vents or ducts to monitor the airflow and pressure distribution in the data center.
