Question:
Before installing a new, upgraded version of the IOS, what should be checked on the router, and Which command should be used to gather this information? (Choose two.)

the amount of available ROM
the amount of available flash and RAM memory
the version of the bootstrap software presents on the router
show version
show processes
show running-config

Explanation: When upgrading new version of the IOS we need to copy the IOS to the Flash so first we have to check if the Flash has enough memory or not. Also running the new IOS may require more RAM than the older one so we should check the available RAM too. We can check both with the “show version” command.
