As far I remind (not having used it for years) LILO can install itself the MBR of all disk of a software RAID just using the device name of the array itself as value of the boot parameter. So if the first disk of the array fails you can still boot from the second (if the BIOS is properly configured and allow you to start from the second one). What I was trying to tell (sorry, but my english knoweledge is quite limited) is that to have the same behaviour with GRUB you have to install it on the MBR of both disk. It can be done quite easily and it's documented by many howto. That's all. But this seem to exceed, at least on my opinion, the level of knoweldge required for an LPI 1 exam.
