While building a VMware View environment one of the design requirements is keeping vCenter
and View Composer always available.
Which solution can be utilized to achieve this?

A vSphere environment is created with two virtual machines, VM23 and VM43. Each virtual
machine has an instance of the front-end web application for the company’s manufacturing

Which type of DRS rule should be implemented for VM23 and VM43?

An administrator is configuring a stretched HA cluster. The administrator wishes to restrict the
failover of VMs to certain hosts within a given site.
Which additional vSphere feature satisfies this requirement?

An administrator is configuring a vSphere HA cluster for three ESXi hosts and their resident virtual
machines. The cluster will be configured to support a single host failure. Resource reservations
must be enforced during a failover event.
Assuming default settings, how does HA determine the current failover capacity?

A network administrator has discovered a failure that has affected connectivity on the
management network cutting the cluster in half. As a result, each half of the ESXi 5.x hosts in a
vSphere HA cluster is able to communicate with each other but not the other half. The cluster was
configured with default settings.
What happens as a result of the failure?

In a vSphere HA cluster, what is the maximum number of point-to-point communication links to the
slaves does each master maintain?

An administrator wants to configure a DRS Migration Threshold that allows automated migration
only when a host is placed into maintenance or to satisfy cluster contraints.
