The correct answer is A. After a stack splits, the MAC addresses of the two stacks change immediately. See the full explanation below for the reasoning.
Question
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 original master/standby switches fail or the entire stack fails after a 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 the same stack after the stack splits, where the original master switch isolates 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.
D. After a stack splits, two or multiple switches have the same original MAC address. To prevent network faults, the stacks perform MAD detection. The stack that fails the MAD detection shuts down all physical ports except reserved ports.

- BIf the original master/standby switches fail or the entire stack fails after a 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.
- CIf the master and standby switches are in the same stack after the stack splits, where the original master switch isolates 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.
