Selected Answer: A
Power feeds to rack come from the external power grid or utility provider, making them an external redundancy. They provide primary power to the data center but are not controlled internally. If external power fails, the data center must rely on internal redundancy (e.g., generators, UPS systems). B. Generators → Internal redundancy → Located inside the data center and provide backup power. C. Power Distribution Units (PDUs) → Internal redundancy → Distributes power within the data center but does not generate or supply it. D. Storage Systems → Internal redundancy → Ensures data availability within the data center, but is not an external backup mechanism.
