Questions and Answers

Which of the following is true about the advantage of a higher priority member over a lower priority member in a network system?

  • The advantage depends on the corrected bandwidth difference.
  • The advantage depends on the link-cost-threshold value. (correct)
  • The advantage depends on the available bandwidth difference.
  • The advantage depends on the physical speed of the interfaces.

When is a lower priority member placed on top of a higher priority member in a network system?

  • When the corrected bandwidth difference is higher than the available bandwidth difference.
  • When the available bandwidth difference is higher than the corrected bandwidth difference. (correct)
  • When the available bandwidth difference is equal to or lower than the corrected bandwidth difference.
  • When the available bandwidth difference is equal to or lower than the available bandwidth difference.

When is a lower priority member placed below a higher priority member in a network system?

  • When the corrected bandwidth difference is higher than the available bandwidth difference.
  • When the available bandwidth difference is higher than the corrected bandwidth difference.
  • When the available bandwidth difference is equal to or lower than the corrected bandwidth difference. (correct)
  • When the available bandwidth difference is equal to or lower than the available bandwidth difference.
