Question 6

What causes most fires in data centres?

  1. Equipment overheating, loose connections, dead shorts
  2. Air conditioner temperature settings, fuel spills, packing material
  3. Lightning strikes, harmonic distortion air conditioner temperature settings
  4. Low relative humidity, lightning strikes air conditioner temperature settings

Question 7

Does shielded twisted pair network cabling provide protection against EMF from power cables?

  1. Yes, but only if the power cable is placed in a tre-foil cable arrangement.
  2. Yes, as the shielding for twisted pair network cabling is specifically design for low frequency EMF protection.
  3. No, the shielding is designed for alien cross-talk between network cables, it provides no or little protection against low frequency EMF.
  4. No, the shielding for twisted pair network cabling is for physical protection against vandalism and accidental cutting of the cable.

Question 8

What is the absolute minimum required space between the slab (building floor) and the raised floor (i.e. raised floor height) when it is used for cold air distribution in the data centre?

  1. 40 cm
  2. 60 cm
  3. 80 cm
  4. 100 cm

Question 9

What is the primary reason to install a monitoring system in the data centre?

  1. To notice abnormalities early so that actions can be taken to avoid disasters
  2. To create a proper asset database
  3. To implement automated change management
  4. To be able to collect data for capacity planning

Question 10

What is the best practice for cutting holes in the raised floor tile?

  1. Anywhere as data centre tiles are designed to allow cut-outs anywhere.
  2. Draw a cross on the tile and when making a cut-out do not touch a line and avoid the corners.
  3. Draw a line in the middle of the tile and never touch the line when making the cut.
  4. Cut the tiles at the corner so the pedestals can be used as a vertical cable manager.
