Network Architecture

Which type of hypervisor is installed directly on top of the server's firmware?

Type 1

How does a vNIC get a MAC address without manual intervention?

Upon creation, each vNIC is automatically assigned a MAC address.

What virtual, logically defined device operates primarily at the data link layer to pass frames between nodes?

Virtual switch

Which of the following features of a network connection between a switch and server is not improved by link aggregation?

Bandwidth

How is licensing an important concern when using virtualization?

Because every instance of commercial software requires its own license, every VM that uses such software comes with added cost.

Which virtual network connection type assigns a VM its IP address from the physical network?

What software allows you to define VMs and manage resource allocation and sharing among VMs on a host computer?

Hypervisor

When you set private IP address ranges for servers in your cloud, what service model are you using?

What are two use cases for a VIP (virtual IP address)?

In some cases, you might have a set of IP addresses to share among multiple hosts. Another scenario is when pooling servers that host VMs.
