• Question 43:

  Which statement is true regarding STP?

  A. When the spanning-tree topology is calculated based on default parameters, the path between the source and destination end stations in a switched network might not be ideal.
  B. The path between the source and the destination end stations is always ideal with the default spanning-tree parameter.
  C. The path between the source and the destination end stations is determined by the speed of the link; the slowest link speed will become the root port during the election.
  D. The path between the source and the destination end stations is determined by the lowest MAC address; the lowest MAC address will become the root port during the election.
  A. When the spanning-tree topology is calculated based on default parameters, the path between the source and destination end stations in a switched network might not be ideal.
