In configuring a VMware HA Cluster the System Administrator can configure Admission Control. There are two options: Prevent VMs from being powered on if they violate availability constraints, or Allow VMs to be powered on even if they violate availability constraints. If the System Administrator chooses the option Prevent VMs from being powered on if they violate availability constraints then which of the following apply in the event of an ESX Host failure (Choose Two)?
A.
VMware HA enforces the failover capacity defined for the cluster
B.
Only Virtual Machines with a high restart priority will be restarted on surviving ESX Hosts
C.
Virtual Machines running on failed ESX Hosts will not be restarted on surviving ESX Hosts
D.
VMware HA restarts Virtual Machines on surviving hosts with the most unreserved capacity
Explanation:
vSphere Availability Guide ESX 4.0 ESXi 4.0 vCenter Server 4.0, page 12 and 13.You can configure VMware HA to tolerate a specified number of host failures. With the Host Failures Cluster Tolerates admission control policy, VMware HA ensures that a specified number of hosts can fail and sufficient resources remain in the cluster to fail over all the virtual machines from those hosts.
In the event of a host failure, the virtual machines running on that host are failed over, that is, restarted on the alternate hosts with the most available unreserved capacity (CPU and memory.)
