In configuing 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 opition Allow VMs to be powered on even if they violate availability constraints then which of the following apply in the even of an ESX Host failure (Choose Two)?
A.
Virhal machines can be powered on until the percentage of cluster resources reaches 25%
B.
Only Virhal machines with a high restart priority will be restarted on surviving ESX Hosts
C.
VMware HA restarts Virtual machines on surviving hosts with the most unreserved capacity
D.
VMware HA cannot guarantee that all VMs from a failed host will be restarted
E.
VMware HA enforces the failover capacity defined for the cluster.
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.)
