A customer wants to virtualize an Oracle database with vSphere 6.5, but is concerned about its performance.
Which three design elements will ensure optimum performance? (Choose three.)
A. Share as much memory as possible with the balloon driver.
B. Use VMXNET3 for the network adapter.
C. Create affinity rules for the virtual machine to a single physical socket.
D. Use VMware Paravirtual SCSI adapters for data and log vDisk.
E. Enable Hyper-Threading.
A) No – ballooning means memory exhaustion and therefore worse performance
B) Yes – VMXNET3 provides the best network performance
C) No – Although this might improve performance when NUMA is involved, this is not the case (see also point 5.3 of the pdf below)
D) Yes – Paravirtual SCSI provides the best adapter performance
E) Yes – Hyper-Threading enables two threads to run simultaneously
B, D, E
