You have added a new switch to a Cisco StackWise stack. If the previous master switch remains the master switch after the master election, which action does the master take?
A. It clears the MAC table of the stack and relearns the attached devices.
B. It removes any Layer 3 configuration on the new switch to maintain normal Layer 2 functionality on the stack.
C. It checks the IOS and running configuration of the new switch and updates them if necessary to match the other switches in the stack.
D. It suspends traffic forwarding until the new switch is updated with the current running configuration of the stack.

Online Stack Adds and Removals
Switches can be added and deleted to a working stack without affecting the backplane performance. When a new
switch is added, the master switch automatically configures the unit with the currently running Cisco IOS® software
image and configuration of the stack. The stack will gather information such as switching table information and
update the MAC tables as new addresses are learned. The network manager does not have to do anything to bring
up the switch before it is ready to operate. Similarly, switches can be removed from a working stack without any
operational effect on the remaining switches. When the stack discovers that a series of ports is no longer present, it
will update this information without affecting forwarding or routing.
