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. After a stack splits, multiple stacks have the same IP address and 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.
- 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.
- D. 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.
Correct Answer: A 🗳️
