2 FLASH contains the standard IOS image

2a. TFTP (optional) contains ios image

3 NVRAM contains the startup config

Yea, this is what i think. but according to the answer explanation i got, the question is asking about the order to locate an usable IOS file. Then it should be: flash, tftp, ROM. but i am not sure about NVRAM, cuz it is usually too small to store an IOS. maybe the answer is wrong.

The IOS should load as you mentioned, Flash, TFTP, ROM.

Default boot sequence for Cisco IOS software:


2. Flash (sequential)

3. TFTP server (network boot)

4. ROM (partial IOS)

How could a NVRAM holds an IOS? It is usually only 32K, but an IOS needs at least few megabytes.
