Answer 2

1) You could argue that all are critical to backup, but I'd go with "a"

/var - contains logs which are important for security audits.



** If you had said /home or /export/home, I'd have gone with that choice. The other directories change infrequently (except /tmp, but that's temporary usage)





2) b



3) d or some other apps structure. I've always left /opt to OS vendor apps while putting third party in an /apps structure



4) c (unless you had a typo on e where "," should be ";")



5) a



6) b



7) b



8) a (although depends which "ps" command you use on some UNIX systems)



9) a & c



Extra: As far as I recall, each one can be on it's own filesystem.
