Which three requirements must be met in order to use Storage I/O Control? (Choose three.)
A. The datastore must contain multiple VMFS extents.
B. The datastore must contain a single NFS volume.
C. The datastore must not include virtual machines with snapshots.
D. The datastore must be managed by a single vCenter Server.
E. Array-based automated storage tiering must be explicitly certified.
What number of IOPS should be used with Storage I/O Control to limit disk throughput to roughly 10 MBps if the guest application writes 64KB blocks?
It appears that a single vCPU virtual machine in a resource pool called Production is having performance problems because it does not have enough CPU resources available. Which two methods can be used to improve performance and reduce CPU contention of this virtual machine while maintaining compatibility with DRS? (Choose two.)
A. Configure a CPU reservation for this virtual machine.
B. Increase the CPU shares for the resource pool.
C. Increase the CPU shares for the virtual machine.
D. Increase the share priority setting for the Production resource pool.
An administrator is performing maintenance on a storage array used by an ESXi 5.x host. The administrator wants to disable alarm actions for the host while the maintenance is taking place. What procedure will accomplish this task?
A. Go to the Alarms tab for each ESXi host in the DRS cluster. Locate storage-related alarms. Right-click and disable each alarm.
B. Right-click the DRS cluster and select Alarm and Disable Alarm Actions.
C. Right-click the ESXi host and select Alarm and Disable Alarm Actions.
D. Go to the Alarms tab for the Datacenter containing the DRS cluster. Locate the storage-related alarms. Right-click and disable each alarm.
An administrator would like to have vCenter take action any time a virtual machine is using over 90% of its available resources for five minutes or longer. Which three actions can be taken by vCenter Server in response to the trigger without running a script? (Choose three.)
A. Power on a VM
B. Reboot Guest on VM
C. Increase Virtual Machine Memory
D. Migrate a VM
E. Increase Virtual Machine CPU Shares

B. Virtual Machine
D. Resource Pool
An administrator has purchased a new 10GB Converged Network Adapter (CNA) for installation in a system that is running ESXi 5.x. The administrator has downloaded the latest driver from the hardware vendor and wants to include the driver in an image. The image profile acceptance level is set to VMwareSupported. The acceptance level of the driver is VMwareSupported. Which two statements are true about the inclusion of this driver in the image? (Choose two.)
A. Support calls for the driver will be directed to the partner.
B. The image can be built, but the driver will not be included in the image.
C. The image can be built and the driver will be included.
D. Support calls for the driver will be handled by VMware.
