Explanation

Power Distribution Units (PDUs) are equipment located inside the data center that distribute electrical power from a source to servers and other IT equipment. Redundant PDUs are a classic example of internal redundancy - they exist within the data center facility itself. Network circuits (B) are external connections linking the data center to the internet or other networks. Power substations (C) are external utility infrastructure that supply power to the building. Generators (D) are typically located outside the building as an external backup power source. The key distinction is that PDUs are inside the data center, making them internal, while the others are external to the facility.
