Which caused this issue?

A number of virtual machines in a vSphere 5.5 DRS cluster are connected to the same
virtual switch port group. After several of these VMs are migrated to another host, an
administrator notices that they have lost network connectivity. The Events tab in vCenter
Server shows this error message: Failed to initialize ethernet0. The vmkernel log file on the
host running the affected VMs contains this message: Can’t connect device:’port group
name’: Out of resources. Which caused this issue?

Which configuration option should the VMware administrator use to resolve this issue?

A VMware administrator determines that a low priority virtual machine is negatively affecting
the disk I/O performance of a higher priority virtual machine. The virtual machines are
hosted on the same datastore presented to the same ESXi host. Which configuration option
should the VMware administrator use to resolve this issue?

What impact on the virtual machines’ performance will be observed?

An administrator decreases the CPU share value for two virtual machines in a DRS cluster
from 1000 to 100 shares. The DRS cluster contains more resources than both virtual

machines can consume. The characteristics of the virtual machines are listed below: • The
second virtual machine is a clone of the first virtual machine. • Both virtual machines are
identical in every way. • Both virtual machines are not attached to the IP network. • Both
virtual machines are powered on. What impact on the virtual machines’ performance will be
observed?
