• A.Only usable in rooms with sufficient air changes
• B.Only usable with positive pressure rooms
• C.Only usable in non-occupied areas
• D.Gas containers must be close to hazard

Given: A = attenuation in dB, R = real measured value, M = maximum acceptable value. Which formula should be used to calculate the required attenuation factor of EMF shielding material?

• A.A = 20 log (M/R)
• B.A = 10 log (R/M)
• C.A = 20 log (R/M)
• D.A = 10 log (M/R)

When shielding material reaches its saturation point, what will be the impact?

• A.The shielding material will no longer be able to attenuate (reduce) additional EMF.
• B.The shielding material will increase its permeability factor.
• C.The shielding material will reach its maximum electrically charged state.
• D.The shielding material will reach its optimal shielding performance state.

What is a potential disadvantage of using a hypoxic-based fire suppression system as a fire extinguishing system?

• A.It can only be used in computer rooms which have sufficient air changes per hour.
• B.It can only be used in computer rooms where you have sufficient positive pressure.
• C.It can only be used in non-continuous occupied areas.
• D.The gas containers need to be close to the hazard area.
