Difficulty: MediumPhysical Security Controls and Environmental Measures

A network engineer is establishing physical and environmental controls for a newly constructed remote edge data facility. To prevent hardware failure from static accumulation, moisture buildup, and inefficient thermal distribution, which TWO of the following environmental deployment strategies should be implemented? (Select TWO.)

  1. Maintain relative humidity levels within the room between 40% and 55%.Answer
  2. Arrange equipment chassis into alternating hot-aisle and cold-aisle containment rows.Answer
  3. C
    Reduce ambient humidity below 20% to eliminate condensation hazards.
  4. D
    Install a wet-pipe sprinkler system directly above the server racks for rapid cooling.
  5. E
    Position intake fans to blow warm air directly onto cabinet front bezels.

Answer

The correct physical and environmental measures are maintaining relative humidity between 40% and 55% and arranging equipment into alternating hot-aisle and cold-aisle containment rows.
Maintaining relative humidity between 40% and 55% prevents both static electricity accumulation (ESD) and water condensation. Additionally, implementing hot-aisle/cold-aisle containment optimizes airflow by separating cold intake air from hot exhaust air, preventing thermal recirculation.

Step-by-Step Solution

1
Analyze environmental humidity requirements.
Relative humidity must be kept in a moderate range (40%–55%). Too low causes electrostatic discharge (ESD); too high causes condensation.
Protecting network components against both ESD buildup and corrosion requires controlled humidity.
2
Analyze airflow and cooling containment measures.
Organizing server racks in alternating hot-aisle and cold-aisle configurations ensures cool intake air isn't mixed with hot exhaust air.
Separating air streams improves HVAC efficiency and reduces thermal stress on network hardware.
