When migrating a machine with vMotion, what are two differences between high priority and standard priority? (Choose two.)
A.
High priority reserves resources on the host and destination. High priority migrations will not proceed if the resources are unavailable.
B.
Standard priority does not reserve resources on the host and destination. Standard priority migrations always proceed.
C.
Standard priority does not reserve resources on the host and destination. Standard priority migrations will not proceed if the resources are unavailable.
D.
High priority reserves resources on the host and destination. High priority migrations always proceed.
This question is outdated, be careful on an exam if they present this question and word it with regards to vSphere/ESXi 5. See below.
From http://pubs.vmware.com/vsphere-50/index.jsp?topic=%2Fcom.vmware.vsphere.vm_admin.doc_50%2FGUID-0542FCAA-209A-4296-8AA4-0A51C13A6233.html
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.
Thanks for your info . If u have any tips . Plz share it
so correct answer should be B and D could you please fix
D is correct but B no. In Standard Priority and ESX/ESXi 4.1 and 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.
Then there isn’t a correct second option.
Yes, there can be only one correct answer i.e. D because both priorities reserves the resource, only difference is in sizes.
