True or False:

> Data may be recovered after a drive failure in a RAID 0 configuration.

  • True
  • False

Which video cable can send both digital and analog signals?

  • DVI-D
  • DVI-I
  • HDMI

  • Thermal paste has no benefits in modern processors
  • Acts as a cooling gel to reduce CPU temperature

You are helping a friend build a new gaming PC. To save on costs they have opted to buy a new motherboard but keep their existing DDR2 memory from their previous PC. After having some trouble getting the memory to fit into the motherboard you check the motherboard manufacturer's documentation and find they recommend their own DDR3 memory. How should you proceed?

  • Purchase a DDR2 to DDR3 slot adapter
  • Buy the recommended memory from the same manufacturer as the motherboard
  • Purchase DDR3 memory from any manufacturer
  • Enable the DDR downgrade feature using a jumper on the motherboard's pins

What cooling mechanism provides the lowest temperatures for internal PC components?

  • Heat Sinks
  • Thermal Paste
  • Liquid Cooling
  • Fans
