In the CAP Theorem, what is Consistency?

A customer wants to ensure that their critical application can fail over to another physical host
within the cluster without disruption.
Which feature should be utilized?

An administrator has implemented a hypervisor cluster with high availability enabled. They are
expecting that if any of the physical servers fail, the virtual servers will be transparently migrated to
other hypervisors in the cluster.
When the first hypervisor failure occurs, all of the hosted virtual servers appear offline to users as
they are moved to another host.
What feature should the administrator have implemented to achieve his goal?

A company moved to a new building that contains a fully virtualized data center. They purchased a
building 10 km away and decide to build a second data center at that location. The new data
center will be identical to the first, and applications and services will be mobile between the
locations.
Which WAN connectivity option would provide both the best performance for virtual server mobility
across sites?

A small law firm that does not currently have any virtualization technologies implemented has
recently merged with another firm of approximately the same size.

They are planning to consolidate into a single location. They have decided to virtualize their
servers, and they would like to consolidate storage. The current storage utilization is below 60%.
The budget will not allow them to purchase an array that matches the capacity of the current
storage. However, they cannot justify the application disruption associated with growing storage
over time to meet forecasted capacity requirements.
Which array feature would meet their requirements?
