Difficulty: EasyPhysical Security Controls and Environmental Measures

Match each physical security or environmental control mechanism to its primary function in a network facility.

  • MantrapUses two interlocking doors to control entry and prevent tailgating into sensitive areas.
  • Clean Agent SystemExtinguishes fires using a non-conductive gas that leaves no residue and does not damage electrical hardware.
  • Faraday CageBlocks external electromagnetic fields and radio frequency signals from entering or escaping an area.
  • Environmental SensorMonitors ambient conditions such as relative humidity, temperature, and water leakage in server rooms.

Answer

Mantrap pairs with interlocking doors; Clean Agent System pairs with non-conductive gas fire suppression; Faraday Cage pairs with blocking electromagnetic fields; Environmental Sensor pairs with monitoring relative humidity and temperature.
Each control mechanism aligns directly with its primary defensive role: a mantrap prevents unauthorized access via interlocking doors, clean agent systems suppress fires without damaging electrical hardware, Faraday cages block electromagnetic interference, and environmental sensors alert administrators to climate shifts.

Step-by-Step Solution

1
Identify the physical access control mechanism designed specifically to stop tailgating.
Mantrap corresponds to the interlocking door system.
Mantraps enforce single-person access control by locking one door until the adjacent door is secured.
2
Determine the appropriate fire suppression method for server equipment sensitive to liquid damage.
Clean Agent System corresponds to non-conductive gaseous fire suppression.
Standard water sprinklers cause severe electrical damage, whereas clean gaseous agents extinguish fires safely.
3
Identify the protective shielding designed to block RF signals and EMI.
Faraday Cage corresponds to blocking external electromagnetic fields.
Solid or mesh conductive enclosures isolate sensitive equipment from external wireless signals and interference.
4
Select the component responsible for measuring room climate conditions.
Environmental Sensor corresponds to monitoring ambient humidity and temperature.
Sensors provide continuous alerts for thermal or moisture anomalies in server environments.
