SG0-001 · Question #230

Which of the following will MOST likely remove a single point of failure in the storage network architecture?

The correct answer is C. Multiple power circuits available in each rack. To eliminate a single point of failure in a storage network architecture, providing multiple, redundant power circuits to each rack ensures continuous operation even if one power source fails.

Why each option

To eliminate a single point of failure in a storage network architecture, providing multiple, redundant power circuits to each rack ensures continuous operation even if one power source fails.

AAdequate heating and ventilation to each rack

Adequate heating and ventilation prevents hardware damage but does not remove a single point of failure related to the active components or their connectivity.

BFloor and rack loading within acceptable weight limits

Floor and rack loading pertains to physical infrastructure integrity and safety, not the removal of an operational single point of failure in the network architecture.

CMultiple power circuits available in each rackCorrect

Power is a critical dependency for all IT equipment, including storage network components. If a single power circuit fails, all equipment connected to it will lose power, creating a single point of failure. Providing multiple, independent power circuits ensures that if one circuit becomes unavailable, the equipment can draw power from another, thereby maintaining uptime and removing power as a single point of failure.

DMaintained and tested fire suppression equipment

Maintained and tested fire suppression equipment is for disaster mitigation, not for preventing an operational single point of failure in the storage network architecture itself.
