Before installing a new upgraded version of the IOS, what should be checked on the router, and which command would be used to gather this information? (Choose two.)
A. show processes
B. The version of the bootstrap software present on the router
C. The amount of available flash and RAM memory
D. The amount of available ROM
E. show running-config
F. show version
The correct answer is C and F.
The show version command will display the current version of IOS, the bootstrap version and physical characteristics of the device, including flash and RAM memory. Each version of IOS has a minimum required amount of flash and RAM needed to be able to operate, therefore you need to confirm that the IOS will fit into its new device.
