   A company is designing a high-availability data center. They have two independent power feeds, each with its own UPS. They plan to use dual-corded PowerEdge servers. The IT architect is considering two designs: (A) each server's two power supplies are connected to two different PDUs, each fed from a different UPS; (B) each server's two power supplies are connected to the same PDU, but the PDU is fed from both UPSs. Which design provides better availability?

   • ABoth designs provide the same availability
   • BDesign A
   • CDesign B
   • DNeither design provides redundancy

   A data center is deploying 12 PowerEdge servers, each with a 1600W power supply. The facility has 208V three-phase power. Each rack has a 30A three-phase PDU. The IT manager wants to ensure that if one phase fails, the servers on that phase can be supported by the remaining phases. What is the maximum number of servers that can be safely connected to the PDU, assuming each server is connected to a single phase and the 80% rule?

   • A12 servers
   • B9 servers
   • C4 servers
   • D6 servers
