Some routers and switches in a wiring closet malfunctioned after an air conditioning unit failed. What type of threat does this situation describe?

  • configuration
  • environmental
  • electrical
  • maintenance
    Explanation:

    The four classes of threats are as follows:

    • Hardware threats – physical damage to servers, routers, switches, cabling plant, and workstations
    • Environmental threats – temperature extremes (too hot or too cold) or humidity extremes (too wet or too dry)
    • Electrical threats – voltage spikes, insufficient supply voltage (brownouts), unconditioned power (noise), and total power loss
    • Maintenance threats – poor handling of key electrical components (electrostatic discharge), lack of critical spare parts, poor cabling, and poor labeling
