Question

An architect is responsible for the following customer considerations in a hardware refresh:

  • Capacity planning will ensure that the environment does not exceed 70% of peak-average

utilization on deployment.

  • CPU purchases will favor clock speed and last level cache over cores per socket.
  • Additional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70%

for 3 consecutive business days.

  • Path Selection policy will be set to round robin and set to switch paths with every SCSI

command.

  • vCPU to pCPU ratio may not exceed 5:1.

What are three considerations when designing for performance? (Choose three.)

Options

  • APath Selection policy will be set to round robin and set to switch paths with every SCSI command.
  • BvCPU to pCPU ratio may not exceed 5:1.
  • CCapacity planning will ensure that the environment does not exceed 70% of peak-average
  • DAll ESXi hosts must have four paths to the storage array.
  • ECPU purchases will favor clock speed and last level cache over cores per socket.
  • FAdditional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70%

Explanation

vCPU to pCPU ratio may not exceed 5:1. This ensures that the virtual CPU (vCPU) allocation is balanced with the physical CPU (pCPU) resources. A ratio that exceeds 5:1 can lead to CPU contention, negatively impacting performance. By maintaining this ratio, the architect ensures that the workloads have sufficient CPU resources for optimal performance. CPU purchases will favor clock speed and last level cache over cores per socket. This is an important performance consideration. Choosing CPUs with higher clock speed and larger last-level cache (LLC) ensures that workloads requiring higher single-threaded performance are optimized. This decision favors workloads that benefit from faster CPU processing and larger cache sizes, improving overall performance. Additional ESXi hosts will be added to the cluster when CPU or memory utilization exceeds 70% for 3 consecutive business days. This performance-related decision ensures that the environment remains responsive under load. Adding additional hosts when resource utilization exceeds thresholds helps prevent bottlenecks and ensures continued optimal performance by distributing workloads across more physical
