The Advanced network adapter is the third generation version of this adapter and was introduced with vSphere.LSI Logic SCSI adapterExplanation: LSI Logic and BusLogic SCSI adapters have been available in ESX for quite some time. The Paravirtualized SCSI (PVSCSI) adapter was created by VMware and introduced with vSphere.Note: This response is either incorrect, or additional responses may be required to receive a 100% score for this question. Question: Which of the following has no effect on the amount of physical memory resources used for virtualization overhead (Choose Two)?Incorrect response(s):Increasing the amount of RAM in the virtual machine.Explanation: Larger amounts of virtual machine memory will increase the amount of overhead to the virtual machine. Adjusting memory share values affects priority access to resources when contention exists, but does not increase or decrease a virtual machine's overhead. Operating System architecture affected memory overhead in earlier generations of ESX, but does not impact overhead in vSphere 4.xIncreasing the number of virtual CPUs in the virtual machine.Explanation: Increasing the number of virtual CPUs in the virtual machine will increase the overhead for the virtual machine.

Question: What two things are controlled by the DRS automation level (Choose Two)?Incorrect response(s):VM restart priorityExplanation: VM restart priority is a VMware HA setting that determines the order in which virtual machines will be restarted if an ESX Host fails. DRS automation controls where a virtual machine is placed within the cluster and balances virtual machine workloads using VMotion migration.Initial placement of VMsNote: This response is either incorrect, or additional responses may be required to receive a 100% score for this question.
