   A VCF administrator is optimizing a VM that runs a critical application. The VM has a memory reservation of 8 GB and a memory limit of 16 GB. The VM is configured with 16 GB of memory. The host is under memory contention. The administrator wants to ensure the VM's performance is not degraded by memory reclamation. What should the administrator do?

   • ADisable memory ballooning for the VM.
   • BIncrease the memory reservation to 16 GB.
   • CIncrease the memory shares for the VM.
   • DIncrease the memory limit to 32 GB.

   A VCF administrator is troubleshooting network performance for a VM that runs a latency-sensitive application. The VM is configured with a virtual e1000e network adapter. The host has a 10 GbE physical NIC that supports SR-IOV. The VM's traffic is primarily east-west between VMs on the same host. Which configuration change is most likely to improve network performance?

   • AEnable traffic shaping on the virtual switch to prioritize the VM's traffic.
   • BChange the VM's network adapter to VMXNET3.
   • CEnable SR-IOV on the VM's network adapter.
   • DIncrease the number of RX/TX queues on the VM's network adapter.
