Question:
Which two benefits can you get by stacking Cisco switches?(choose two)
- Each switch in the stack handles the MAC table independently from the others
- You can add or remove switches without taking the stack down.
- Each switch in the stack can use a different IOS image
- The stack enables any active member to take over as the master switch if the existing master fails.
- You can license the entire stack with a single master license
Explanation: Each stack has only one configuration file, which is distributed to each member in the stack. This allows each switch in the stack to share the same network topology, MAC address, and routing information. In addition, it allows for any member to become the master, if the master ever fails -> Answer D is correct while answer A is not correct.
Switches can be added and deleted to a working stack without affecting stack 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. A working stack can accept new members or delete old ones without service interruption -> Answer B is correct.
