Question

Options

• AEMI
• BESD
• CBroadcast storm
• DSurge

• A
  77% (30)

  13% (5)
• C
  8% (3)
• D
  3% (1)

Explanation

If the power cable runs along with the computer network cable, radiation from the power cable, known as electromagnetic interference (EMI) , may be inducted into the computer network cable affecting the signals that pass through it. Answer option B is incorrect. ESD stands for Electrostatic discharge. The static electricity that we generate everyday creates ESD. If you walk across a carpet and touch someone, you experience a mild shock. Electrostatic discharge occurs when the electrostatic charge is transferred from one charged entity to another entity sensitive to that charge.To minimize Electrostatic discharge (ESD) problems, consider wearing a wrist strap when you are working with computer components. A wrist strap is a wire with a watchband-style strap at one end and a plug or clip on the other end. The wrist strap plug or clip is connected to the ground or to the piece of equipment being worked on. Answer option D is incorrect. Surge is a momentary voltage variation (+/- 170 volts) that lasts from one microsecond to a few milliseconds. Turning on and off large inductive electrical devices such as air conditioners and refrigerators can cause a surge. Answer option C is incorrect. Broadcast storm is a situation in which one or more network devices send jabber packets constantly, thereby increasing the traffic. A faulty network interface card (NIC) that sends jabber packets can be detected by the network monitor software. A faulty NIC can cause a broadcast storm on the network. Broadcast storms caused by a faulty network interface card can be resolved by disabling or replacing the card.
