CCNA question about boot files

Unanswered Question
Oct 23rd, 2007

As a Certkiller.com instructor you are required to place the following items to the correct order they are used when Cisco IOS based hardware is booted.

Flash, NVRAM, TFTP, ROM.

What should be the correct order? Thanks.

I have this problem too.

1 ROM contains the bootstrap image

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.

I believe the NVRAM only holds the

startup-config

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

I am new to this so I could be mistaken.

Default boot sequence for Cisco IOS software:

1. NVRAM

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.
