Air mounted systems are compact, easy to install and maintain, and can be a cost-effective solution for small spaces.
NEW QUESTION # 20
The distance that a signal's energy can travel in the time it takes for one cycle to occur is called the signal's:
- A. wavelength
- B. frequency
- C. amplitude
- D. period
Answer: A
Explanation:
Explanation
Wavelength is a measure of the distance that a signal's energy can travel in the time it takes for one cycle of the signal to occur. It is calculated by dividing the speed of light by the frequency of the signal. Wavelength is generally expressed in meters (m).

NEW QUESTION # 23
Which one of the following describes the amount of resistance electricity encounters?
- A. Ampere
- B. Volts
- C. Watts
- D. Ohm
Answer: D
Explanation:
Explanation
Ohm () describes the amount of resistance electricity encounters. It is one of the base units of the International System of Units (SI), and is defined as the amount of resistance that a conductor has when a force of one volt is applied across it. Ohms are used to measure the electrical resistance of a circuit, and can be used to determine the power of a circuit or the amount of current flowing through it.
NEW QUESTION # 24
Which one of the following is an overall consideration for physical security?
- A. Apply the technology
- B. Apply the solution
- C. Identify the problem
- D. Define the problem
Answer: D
Explanation:
Explanation
Defining the problem is an important overall consideration for physical security. This process involves identifying and analyzing the threats and vulnerabilities that could potentially affect the security of the system, as well as determining what steps need to be taken to mitigate these risks. This process should be done before any other steps are taken to ensure physical security, as it helps to ensure that the security measures are tailored to the specific needs of the system.
NEW QUESTION # 25
Which system in Air Distribution System takes the hot exhaust air from the IT equipment to the CRAC
- A. Maintenance system
- B. Regulation system
- C. Supply system
- D. Return system
Answer: D
Explanation:
Explanation
The return system in an air distribution system takes the hot exhaust air from the IT equipment and returns it to the Computer Room Air Conditioner (CRAC) unit. The CRAC unit cools the hot exhaust air and recirculates it back into the data center. The return system typically includes ducts, grills, and other components that allow the hot air to be efficiently and effectively returned to the CRAC unit.
Supply system is responsible for bringing in the cooled and filtered air from the CRAC unit to the data center.
Maintenance system and regulation system are not related to air distribution system in the data center.
