question 20

Multiple Choice

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.
