QUESTION 6
ACME Junkmail Incorporated has been utilizing templates in their environment. They are running a 10-node ESXi 5.x Cluster and DRS has not been configured. Several virtual machines have been deployed from this template and successfully powered on, but a newly deployed virtual machine will not power on. There appear to be adequate CPU and Memory resources available on the host.

Which three things can be done to allow more virtual machines to be deployed into the cluster from this template? (Choose three.)

A.        Select a different datastore for the virtual machine
B.        Move the swap file to a different location
C.        Deploy the virtual machine to a different host using the same datastore
D.        Enable DRS on the cluster to balance the virtual machine load
out across hosts
E.        Increase the virtual machine memory reservation

Answer: ABE

E选项说增加内存，题上给出的信息是不缺内存，造成的错误，有高手知道为啥要选E不？

E答案是说增加预留内存，而不是增加内存
增加预留内存，可以减少交换文件占用空间，和B的做法效果差不多
