Zorluk: KolayPhysical Security Controls and Environmental Measures

A network technician is configuring environmental controls for a server room housing sensitive equipment. To minimize the risk of electrostatic discharge (ESD) damaging internal hardware components, which environmental measure should be maintained within standard recommended thresholds?

  1. Ambient relative humidity levelsCevap
  2. B
    SNMPv3 cryptographic authentication settings
  3. C
    Access Control List (ACL) implicit deny rules
  4. D
    TACACS+ centralized authorization protocols

Cevap

Maintaining proper ambient relative humidity levels is the primary environmental control used to prevent electrostatic discharge (ESD) buildup in network equipment facilities.
Electrostatic discharge occurs when dry air allows static charges to accumulate on physical surfaces and personnel. Maintaining ambient relative humidity at recommended target levels (typically 40% to 55%) ensures sufficient air moisture to dissipate static charges safely before they reach network hardware.

Adım Adım Çözüm

1
Identify the physical security/environmental hazard described in the scenario.
The target threat is electrostatic discharge (ESD), which can destroy electronic micro-components.
Understanding the physical mechanics of ESD is necessary to select the appropriate environmental countermeasure.
2
Evaluate how environmental metrics control static electricity.
Low humidity creates dry air, causing static electricity to accumulate easily on objects and human bodies. Maintaining appropriate relative humidity keeps moisture levels sufficient to ground static charges harmlessly.
Environmental control of moisture (humidity) directly mitigates ESD risks in server rooms and wiring closets.
