A storage area network (SAN) was inadvertently powered off while power maintenance was being performed in a datacenter. None of the systems should have lost all power during the maintenance. Upon review, it is discovered that a SAN administrator moved a power plug when testing the SAN’s fault notification features.
Which of the following should be done to prevent this issue from reoccurring?
A. Ensure both power supplies on the SAN are serviced by separate circuits, so that if one circuit goes down, the other remains powered.
B. Install additional batteries in the SAN power supplies with enough capacity to keep the system powered on during maintenance operations.
C. Ensure power configuration is covered in the datacenter change management policy and have the SAN administrator review this policy.
D. Install a third power supply in the SAN so loss of any power intuit does not result in the SAN completely powering off.

While CompTIA and does harp on change management procedures a lot, and that would HELP in preventing this type of thing from happening…. Having the SAN plugged into a separate power source(circuit) will totally prevent the SAN from completely powering off when one of the power supplies are unplugged 100% of the time.
Both A and C can be right, but I believe A is more correct simply because C relies on there being no human error. Where A provides some redundancy.
the correct answer is really C
