Difficulty: EasyPhysical Security Controls and Environmental Measures

A network technician needs to safeguard a remote equipment room against electrostatic discharge (ESD) and prevent unauthorized physical tampering with individual server hardware inside shared enclosures. Which TWO of the following controls should be deployed to meet these specific requirements? (Select TWO)

  1. Maintain relative humidity levels between 40% and 55% within the equipment roomAnswer
  2. Install smart card locking door handles and secure side panels on server racksAnswer
  3. C
    Lower relative humidity below 20% to eliminate moisture accumulation on circuit boards
  4. D
    Deploy a wet-pipe sprinkler system directly above the server rack cabinets
  5. E
    Replace standard copper cabling with plenum-rated patch cables to absorb electrostatic charges

Answer

Maintaining relative humidity between 40% and 55%, and installing smart card locks with secure side panels on server racks.
Maintaining humidity levels between 40% and 55% dissipates static charges in the air to protect sensitive components from ESD. Rack-level smart card locks and secure side panels provide physical containment and access logging specifically for equipment cabinets.

Step-by-Step Solution

1
Identify the environmental control needed to prevent electrostatic discharge (ESD).
Relative humidity kept between 40% and 55% prevents static electricity from accumulating in dry air while avoiding condensation.
Air that is too dry generates static electricity, whereas proper humidity management dissipates ESD potential.
2
Identify the physical security control needed to prevent tampering at the rack cabinet level.
Smart card locking handles combined with solid or locked side panels secure individual server equipment inside enclosures.
Limiting access to the server rack ensures unauthorized individuals cannot open cabinet doors or access exposed server hardware.
