• Question 157:

  Which of the following statements about stack split is false?

  A. After a stack splits, the MAC addresses of the two stacks change immediately.
  B. If the master and standby switches are still in the same stack after the stack splits, the slave switches separated from the original master and standby switches re-elect the master and standby switches due to protocol packet timeout.
  C. If the master and standby switches are in two stacks after the split, the stack where the original master switch resides updates the topology and selects a new standby switch. The original standby switch becomes the master switch in the new stack and a new standby switch is elected.
