   A PowerEdge server is configured for memory sparing. The administrator wants to add more memory without changing the operating mode. The server has 12 DIMMs installed, and the administrator adds 4 more DIMMs of the same type. After boot, the system reports less usable memory than expected. What is the most likely cause?

   • AThe new DIMMs are slower than the existing DIMMs, causing the system to run at a lower speed.
   • BMemory sparing reserves a spare rank per channel, reducing usable capacity.
   • CThe server is configured for memory mirroring, which halves usable memory.
   • DThe new DIMMs are not seated properly, so they are not detected.

   An administrator is installing a new PCIe NVMe SSD adapter into a PowerEdge server. The adapter is a x8 Gen4 card. The server has the following slots: Slot 1 (x16 Gen4), Slot 2 (x8 Gen4), Slot 3 (x16 Gen3), Slot 4 (x8 Gen3). Which slot should the administrator use for optimal performance?

   • ASlot 4
   • BSlot 3
   • CSlot 2
   • DSlot 1

   What is the primary purpose of Advanced ECC (Error Correction Code) memory mode in Dell PowerEdge servers?

   • ATo detect and correct multi-bit memory errors
   • BTo provide a spare memory module for automatic failover
   • CTo increase memory speed beyond the rated speed

   What is a key characteristic of DDR4 memory compared to DDR3?

   • ADDR4 uses a 240-pin DIMM, same as DDR3.
   • BDDR4 operates at a lower voltage (1.2V) and supports higher module densities.
   • CDDR4 has the same data rate as DDR3 but with lower latency.
   • DDDR4 is backward compatible with DDR3 slots.
