  1. cp_from_log_full
  2. cp_from_busy
  3. cp_from_cp
  4. cp_from_timer
Correct answer: AC
Explanation:
http://backdrift.org/man/netapp/man1/na_sysstat.1.html http://redhunter.com/blog/2010/02/11/netapp-consistency-points-in-cacti/ cp_from_log_full (log full) - the current NVRAM bank is full and the system switches to the other one and starts writing this to disk. Very heavy write activity. cp_from_cp (aka Back to Back) - filer is overloaded. The write traffic is coming in faster than it can be written and the filer is running out of NVRAM capacity in one bank before the data in the other bank can be written. cp_from_busy is not a real cp type cp_from_timer - 10 seconds since the last CP – it means the system is pretty idle write-wise.
