Q3. You have a switch in a stack that needs to be replaced. You are concerned that the configuration will be lost for the switch but anyway you go for the replacement , then what will happen when it is replaced?

The replacement switch will automatically download the configuration for the switch member number it’s configured for from the master
The replacement switch will need manual configuration since the interfaces will be renumbered
The replacement switch will need to have its configuration transferred from the existing switch to be replaced
The replacement switch will need to have the configuration TFTP transferred after replacement manually by the network admin

Q6. You want to upgrade the stack’s IOS.What is all that needs to be done . Assumption : model of all switches in the stack is same.

Each switch needs to be upgraded independently
The IOS image cannot be changed once a stack is configured
Each switch in the stack needs to be configured with a TFTP location to boot from, and then they all must be reloaded
Only the master switch needs to be upgraded
