Which two memory settings optimize a PowerEdge 16G server to support VMware ESXi?

Question

Options

• ANear Balanced Configuration and Dell Fault Resilient Mode
• BBalanced Memory Configuration and Dell Fault Resilient Mode
• CBalanced Memory Configuration and Optimizer Mode
• DNear Balanced Configuration and Optimizer Mode

• A
  17% (7)
• B
  5% (2)
• C
  71% (30)
• D
  7% (3)

Explanation

Balanced Memory Configuration ensures DIMMs are populated symmetrically across all available memory channels, maximizing bandwidth - critical for VMware ESXi, which needs high-throughput memory access to support multiple concurrent VMs. Optimizer Mode (the default performance mode) maximizes total usable memory capacity and bandwidth without sacrificing memory to redundancy schemes, making it the ideal pairing for virtualization workloads.

Why the distractors fail:

• Near Balanced Configuration (options A and D) is a suboptimal DIMM placement where channels are not fully or evenly populated, reducing memory bandwidth - a known performance penalty for ESXi.
• Dell Fault Resilient Mode (options A and B) reserves a portion of memory to create a protected region for fault tolerance, which reduces the total memory available to VM guests - the opposite of what ESXi optimization requires.

Memory tip: Think "B.O. for Best Operations" - Balanced + Optimizer = the two settings that give VMware ESXi the most memory bandwidth and capacity without sacrificing resources to redundancy.
