CCT Exam Question. Router will not boot without, what type of memory?

Hello, I was asked this question once and I know that the Router must have both RAM and Flash to boot. But, it only asks for one type of memory. I would say it would be RAM.

Any thoughts?

You can boot router from tftp instead from flash so flash isn't mandatory to boot a router.
So RAM is the right choise.

Power on self test is a test done by processor for processor.

After poser on self test it will move to ROM in which bootstrap program will reside which consists of booting process.

This bootstrap program will have the configure registration value.

ROM ( checks for  boot strap program )

Flash  (if ios is there in flash it will load if no it will check for ftp server and loads in to ram, if ios is not there it will go to rommon mode)

NVRAM (if ios is loaded then it will go Check startup config if it is unavailable in NVRAM it will check for TFTP server

RAM If you are loaded in all then you can edit and read the files in RAM mode
