When migrating a machine with VMotion, what is the difference between
High Priority and Low Priority (Choose Two)?
A.
High priority reserves resources on the host and destination. High priority migrations
always succeed.
B.
High priority reserves resources on the host and destination. High priority migrations
will not proceed if the resources are unavailable.
C.
Low priority does not reserve resources on the host and destination. Low priority
migrations always succeed.
D.
Low priority does not reserve resources on the host and destination. Low priority
migrations will not proceed if the resources are unavailable.
Explanation:
See below.

Hi James : This question don’t have screenshot . I fixed this question. thanks
Actually, i still do not know the difference between high priority and standard priority ,anyone can illustrate?
“High Priority On hosts running ESX/ESXi version 4.1 or later,vCenter Server attempts to reserve resources on both the source and destination hosts to be shared among all concurrent migrations with vMotion. vCenter Server grants a larger share of host CPU resources to high priority migrations than to standard priority migrations. Migrations always proceed regardless of the
resources that have been reserved.
On hosts running ESX/ESXi version 4.0 or earlier, vCenter Server attempts to reserve a fixed amount of resources on both the source and destination hosts for each individual migration. High priority migrations do not proceed if resources are unavailable.
Standard Priority On hosts running ESX/ESXi version 4.1 or later, vCenter Server reserves resources on both the source and destination hosts to be shared among all concurrent migration with vMotion. vCenter Server grants a smaller share of host CPU resources to standard priority migrations than to high priority migrations. Migrations always proceed regardless of the resources that have
been reserved.
On hosts running ESX/ESXi version 4.0 or earlier, vCenter Server attempts to reserve a fixed amount resources on the source and destination hosts for each migration. Standard priority migrations always proceed. However, the migration might proceed more slowly or fail to complete if sufficient resources are not available.”

Is there any reference confirming “low priority migrations always succeed?” I see always proceed but not always succeed.
So why is this question not specifying whether its pre 4.0 or post 4.0. ???
