Avirtual machine performance graph shows the swap In value to be at 95%, and the Balloon value to be at 0%. Users of the VM are complaining that performance is slow. Which of the following actions can be done to increase performance of the VM (Choose Two)?
A.
Migrate the virtual machine to another datastore using Storage VMotion
B.
Change the CPU Share value for this virtual machine to High
C.
Install VMware Tools into this virtual machine
D.
Change the Memory Share value for this virtual machine to High
This answer seems incorrect.
Swap file usage is high which indicates VM is short of memory.
Inspite of memory shortage ballooning is 0 % which indicates Vmware tools is not installed.
Hence correct answers should be C and D.
Anyways what has storage Vmotion to do with memory????

In Answer A, the virtual machine will be improved performance.
“Storage vMotion has a number of uses in administering virtual infrastructure, including the following examples of use:
+ Upgrading datastores without virtual machine downtime. You can migrate running virtual machines from a VMFS2 datastore to a VMFS3 datastore, and upgrade the VMFS2 datastore using a two step process. You can then use Storage vMotion to migrate virtual machines back to the original datastore without any virtual machine downtime. For information on upgrading VmFS2 to VmFS5, see the vSphere Storage documentation.
+ Storage maintenance and reconfiguration. You can use Storage vMotion to move virtual machines off of a storage device to allow maintenance or reconfiguration of the storage device without virtual machine downtime.
+ Redistributing storage load. You can use Storage vMotion to manually redistribute virtual machines or virtual disks to different storage volumes to balance capacity or improve performance.”

problem related to swap and ballooning points to memmory issue.
Moving it to another datastore wont fix this issue.
I agree with gaurav. Answer should be C and D.
VMware tools contains the balooning driver.
