Hi Experts,

I saw a question that said:

What are the things that i should take care before upgrading my IOS with a new version and what the IOS commands should i use to gather the information ?

A)The Rom memory.

b)Flash & Ram memory.

c)Show version.

d)show interfaces.

the answer is very simple it's B and C , but why they said Ram memory in option B answer ..

As i know that Ram not necessary to check it just we should check Flash Memory..

Is it correct ?

Flash is the file system, in other words, it will hold the file you download from Cisco - just like your hard drive.

RAM is what drives the IOS while the system is operating.

Those 2 components are vital when installing a new IOS. When downloading the IOS, those are the values presented to you to make a final decision if you are getting the correct IOS.

Hi Ibrahim,

You should check both RAM (where the IOS would run) and Flash (where the IOS would be saved) (actually when downloading an IOS both are required to be checked) and both can be checked with the "show version" command:
