+ t# M5 ]* \( B% ~8 n6 ]Answer: B 10. You have a dual-processor virtual machine (VM) that has affinity set so that the virtual CPUs are pinned to CPU 3 and 4 in VirtualCenter.The VM also has a reservation setting resources for those two CPUs. Performance is poor in this VM.however performance for all other VMs on this host is acceptable
