- A.Comparing the rack's full-load draw with the PDU and branch circuit capacity after derating

Correct answer:
- A.Comparing the rack's full-load draw with the PDU and branch circuit capacity after derating
Explanation
Capacity planning compares the sustained load of the rack with the PDU and circuit ratings after derating for continuous operation. Cable ties and floor height matter for installation, but they do not confirm that the power supply can carry the load. - A.
- Question 2What is the key difference between AC-powered and DC-powered racks?
- A.DC racks need no grounding at all because direct current has no return path, while AC racks must always be bonded to the building ground through the PDU
- B.AC racks take alternating-current feeds through PDUs, while DC racks receive direct current from a rectifier or power shelf
- C.AC racks cannot use liquid cooling, while DC racks cannot use air cooling
- D.DC racks are always smaller than AC racks in every dimension
Show answerHide answer
Correct answer:
- B.AC racks take alternating-current feeds through PDUs, while DC racks receive direct current from a rectifier or power shelf
Explanation
AC racks receive alternating current through rack PDUs and convert it inside each power supply, while DC racks take direct current from a rectifier or power shelf in the facility. Grounding and cooling are required in both types, which makes the first option the only accurate distinction. - A.
